A novel argument to use 8-bit media processor for low power VLSI design

A novel idea pertaining to the selection of a processor size for low power IC applications has been proposed. 8-bit processors were introduced in the beginning by Intel. Later, technology has rapidly advanced forcing the designers to go for 32-bit and 64-bit processors for edge cutting, high performance technologies. In this paper, it has been proposed that an 8 bit media processor can perform the same applications that the others do, at reduced power consumption and hence is more advantageous than other processor sizes. The main concept of the paper is that, once a VHDL or a Verilog code is designed for any media processing application, its Xilinx synthesis report is converted to transistor level net list by careful observation. This transistor level net list is implemented in Tanner Tools EDA and the power can be easily calculated. By this method, the experimental results have proved that 8-bit processor consumes less power than others and hence can be used in place of 16-bit and 32-bit processor chips.
