In this work, an ascendable low power 64-bit priority encoder is designed using a two-directional array to three-directional array conversion, and Split-logic technique and 6-bit is obtained as the output. By using this method, the high performance priority encoder can be achieved. In the conventional priority encoder, a single bit is set as an input, but for a priority encoder with 3-Darray, every input are specified in the matrix form. The I-bit input file is split hooked on M × N bits, similar to 2-D Matrix. In priority encoder with 3-Darray, three directional output comes out, unlike traditional priority encoder, where the output is received from one direction. The development can be achieved by implementing the two-directional array to three-directional array technique. Simulation results show that the proposed 2-D and 3-D priority encoder consumes 0.087039mW and 0.184014mW which is less when compared with the conventional priority encoder. The priority encoders are simulated and synthesized using VHDL in Xilinx Vivado version 2019.2 and the Oasys synthesis tool.
