VLSI PROJECTS ABSTRACT 2016-2017 A SINGLE-ENDED WITH DYNAMIC FEEDBACK CONTROL 8T SUBTHRESHOLD SRAM CELL ABSTRACT: A novel 8-transistor (8T) static random access memory cell with improved data stability in subthreshold operation is designed. The proposed single-ended with dynamic feedback control 8T static RAM (SRAM) cell enhances the static noise margin (SNM) for ultralow power supply. It achieves write SNM of 1.4× and 1.28× as that of isoarea 6T and read-decoupled 8T (RD-8T), respectively, at 300 mV. The standard deviation of write SNM for 8T cell is reduced to 0.4× and 0.56× as that for 6T and RD-8T, respectively. It also possesses another striking feature of high read SNM ∼2.33×, 1.23×, and 0.89× as that of 5T, 6T, and RD-8T, respectively. The cell has hold SNM of 1.43×, 1.23×, and 1.05× as that of 5T, 6T, and RD-8T, respectively. The write time is 71% lesser than that of single-ended asymmetrical 8T cell. The proposed 8T consumes less write power 0.72×, 0.6×, and 0.85× as that of 5T, 6T, and isoarea RD-8T, respectively. The read power is 0.49× of 5T, 0.48× of 6T, and 0.64× of RD-8T. The power/energy consumption of 1-kb 8T SRAM array during read and write operations is 0.43× and 0.34×, respectively, of 1-kb 6T array. These features enable ultralow power applications of 8T. The proposed architecture of this paper area and power consumption analysis using tanner tool.Existing System: The portable microprocessor controlled devices contain embedded memory, which represents a large portion of the system-on-chip (SoC). These portable systems need ultralow power consuming circuits to utilize battery for longer duration. The power consumption can be minimized using nonconventional device structures, new circuit topologies, and optimizing the architecture. Although, voltage scaling has led to circuit operation in subthreshold regime with minimum power consumption, but there is a disadvantage of exponential reduction in performance. The circuit operation in the subthreshold regime has paved path toward ultralow power embedded memories, mainly static RAMs (SRAMs). However, in subthreshold regime, the data stability of SRAM cell is a severe problem and worsens with the scaling of MOSFET to subnanometer technology. Due to these limitations it becomes difficult to operate the conventional 6-transistor (6T) cell at ultralow voltage (ULV) power supply. In addition, 6T has a severe problem of read disturb. The basic and an effective way to eliminate this problem is the decoupling of true storing node from the bit lines during the read operation. This read decoupling approach is utilized by conventional 8-transistor [read decoupled 8-transistor (RD-8T)] cell which offers read static noise margin (RSNM) comparable with hold static noise margin (HSNM). However, RD-8T suffers from leakage introduced in read path. This leakage current increases with the scaling thereby, increasing the probability of failed read/write operations. Similar cells that maintain the cell current without disturbing the storage node are also proposed.Proposed System: To make a cell stable in all operations, single-ended with dynamic feedback control (SE-DFC) cell is presented in Fig. 1(a). The single-ended design is used to reduce the differential switching power during read–write operation. The power consumed during switching/ toggling of data on single bit line is lesser than that on differential bit-line pair. The SE-DFC enables writing through single nMOS in 8T. It also separates the read and write path and exhibits read decoupling. The structural change of cell is considered to enhance the immunity against the process–voltage–temperature (PVT) variations. It improves the static noise margin (SNM) of 8T cell in subthreshold/near-threshold region. The proposed 8T has one cross coupled inverter pair, in which each inverter is made up of three cascaded transistors. These two stacked cross-coupled inverters: M1–M2–M4 and M8–M6–M5 retain the data during hold mode. The write word line (WWL) controls only one nMOS transistor M7, used to transfer the data from single write bit line (WBL). A separate read bit line (RBL) is used to transfer the data from cell to the output when read word line (RWL) is activated. Two columns biased feedback control signals: FCS1 and FCS2 lines are used to control the feedback cutting transistors: M6 and M2, respectively.ADVANTAGES:• higher power saving capability during read/write operations• higher Static Noise MarginDISADVANTAGES:• Low SNM• High power consumption SOFTWARE IMPLEMENTATION:• Tanner tools

VLSI PROJECTS ABSTRACT 2016-2017 THE VLSI ARCHITECTURE OF A HIGHLY EFFICIENT DEBLOCKING FILTER FOR HEVC SYSTEMS ABSTRACT:This paper presents the VLSI architecture and hardware implementation of a highly efficient Deblocking Filter for High Efficiency Video Coding (HEVC) systems. In order to reduce the number of data accesses and thus to enhance the timing efficiency, novel data structures and memory access schemes for image pixels are proposed. Furthermore, a novel edge-fetching order is presented to strike a balance between the processing throughput and complexity. Based on the proposed structure and access pattern, a six-stage pipelined, two-line Deblocking Filter engine with low-latency data access sequence is designed, aiming to achieve high processing throughput while at the same time maintaining low complexity. The detailed storage structure and data access scheme are illustrated and VLSI architecture for the Deblocking Filter engine is depicted in this paper. In addition, the proposed Deblocking Filter is implemented using TSMC 90nm standard cell library. Experimental results based on post-layout estimations show that the proposed design can achieve 60 frames per second for frame resolution of 4096×2048 pixels (Ultra HD resolution) assuming an operating frequency of 100MHz. Moreover, this design occupies area complexity of 466.5 kGE with power consumption of 26.26 mW. In comparison with prior arts targeting on similar system specification and throughput, the proposed design results in a significantly reduced area complexity.The proposed architecture of this paper analysis the logic size, area and power consumption using Xilinx 14.2. EXISTING SYSTEM: Over the past decades, one of the prominent trends for digital video system lies in the greatly increased resolution such as the High Definition (HD ; 1920×1080) and Ultra HD (409×2048 or 7680×4320) formats. Furthermore, there has been huge demands for accessing digital video contents through wireless signals and/or high-speed transmission interfaces. Therefore, it is paramount to have an efficient video coding (compression) methodology that can significantly reduce the amount of data while at the same time largely maintaining the visual quality. Moreover, this methodology needs to be practically realized so that real-time processing can be achieved with manageable hardware complexity. Recently, the latest video coding standard, High Efficiency Video Coding (HEVC), has been established. It is claimed that the HEVC can reach the same visual quality as its predecessor, H.264/AVC, with halved bit rate. This improvement in coding efficiency of HEVC is mainly due to the introduction of more adaptive and flexible basic coding units. Unlike H.264 standard where each frame is divided into 16×16 Macro Blocks (MB), the basic processing unit in HEVC is the Coding Unit (CU) and its size could be from 8×8 to 64×64.PROPOSED SYSTEM: This paper presents the VLSI architecture and the hardware implement of a highly efficient Deblocking Filter for HEVC systems. In particular, Inspired by the concept of the “Unified Cross Unit” mentioned, the proposed Deblocking filtering operation is based on novel memory structures and data access patterns so that the number of required memory accesses is reduced and the timing efficiency for data accesses is enhanced. Furthermore, a novel edge-fetching order is presented to strike a balance between the processing throughput and complexity. In order to achieve high throughput with low complexity, based on the proposed structure and access pattern, a six-stage pipelined, two-line Deblocking Filter engine with low-latency data access sequence is designed. Instead of using four-line filter, this design can still process the resolution of 4096×2048 at 60 fps with a much simplified two-line filter, mainly due to the proposed efficient data access scheme. The circuit implementation of the proposed design is clearly illustrated and the experimental results based on post layout estimations are presented. Specifically, four sets of video sequences were sent to the post-layout netlist for verifying the functionality. Moreover, detailed performance analyses and comparisons with prior arts are given in order to shed more lights on the trade-offs between different design considerations. We show that, compared to the prior arts targeting on similar system specification and throughput, the proposed design results in a significantly reduced area complexity. In short, main contributions of this paper can be summarized as follows.ADVANTAGES:• low-latency data access• very high processing throughputSOFTWARE IMPLEMENTATION• Modelsim• Xilinx ISE DISADVANTAGES• high-latency data access• low processing throughput

VLSI PROJECTS ABSTRACT 2016-2017 A HIGH-PERFORMANCE FIR FILTER ARCHITECTURE FOR FIXED AND RE CONFIGURABLE APPLICATIONS ABSTRACT: Transpose form finite-impulse response (FIR) filters are inherently pipelined and support multiple constant multiplications (MCM) technique that results in significant saving of computation. However, transpose form configuration does not directly support the block processing unlike direct-form configuration. In this paper, we explore the possibility of realization of block FIR filter in transpose form configuration for area-delay efficient realization of large order FIR filters for both fixed and reconfigurable applications. Based on a detailed computational analysis of transpose form configuration of FIR filter, we have derived a flow graph for transpose form block FIR filter with optimized register complexity. A generalized block formulation is presented for transpose form FIR filter. We have derived a general multiplier-based architecture for the proposed transpose form block filter for reconfigurable applications. A low-complexity design using the MCM scheme is also presented for the block implementation of fixed FIR filters. The proposed structure involves significantly less area delay product (ADP) and less energy per sample (EPS) than the existing block implementation of direct-form structure for medium or large filter lengths, while for the short-length filters, the block implementation of direct-form FIR structure has less ADP and less EPS than the proposed structure. Application specific integrated circuit synthesis result shows that the proposed structure for block size 4 and filter length 64 involves 42% less ADP and 40% less EPS than the best available FIR filter structure proposed for reconfigurable applications. For the same filter length and the same block size, the proposed structure involves 13% less ADP and 12.8% less EPS than those of the existing direct-form block FIR structure. The proposed architecture of this paper analysis the logic size, area and power consumption using Xilinx 14.2. PROPOSED SYSTEM: In phase 1 to discussed about 16 tap FIR filter for Low pass, High pass, Band pass, and band stop filter and to analysis the performance, efficiency, speed, and power consumption for the respective filter types. Fig.6 shows the block diagram of the proposed system. The NCO used for signal generation with required frequency range. NCO is used in the modulation block.
