A design of high performance 64 bit Multiplier-and-Accumulator (MAC) is implemented in this paper. MAC unit performs important operation in many of the digital signal processing (DSP) applications. The multiplier is designed using modified Wallace multiplier and the adder is done with carry save adder. The total design is coded with verilog-HDL and the synthesis is done using Cadence RTL complier...
The clock distribution is important in all synchronous VLSI Design. The clock skew impacts the performance of synchronous logic circuits. As the scaling moves to nanometer technology, innovative clocking techniques are required to optimize the skew. This is done in backend process of design flow, (i.e.) skew is optimized in Pre and Post CTS. Here tunable clock buffers and tunable clock inverters is...
Sub threshold leakage current has increased dramatically with technology scaling and it consumes a significant portion of the total power. In order to reduce the leakage current, one of the efficient method is power gating. The main challenge in power gating is, to design switching fabric and power controller. In this paper the main aim is to implement power gating in semicustom design. For this we...
