64-bit Multi-match Priority Encoder (MPE64) for High Performance VLSI Architectures

Encoders are crucial for digital storage, memory technologies. There exist many approaches to increase the performance of encoders. In this paper, we considered 8-bit and 64-bit prioritized encoders, where LSB bit in the input is given higher priority and prioritization is carried out prior to encoder process. Thereby, latency in 64-bit is at least 8 times that of latency in 8-bit. Further using multi-match priority in which input 64 bit is split into 8 sections and prioritization is done prior to encoder which improves the performance. Simulation is carried out in Xilinx.
