Description
TotalCPU is RISC core with 12-bit instruction width and variable data width (from 12 to 64 bits). It is completely realized on Verilog-2001 and has two variants of implementation - with program counter placed in register block or defined as a standalone register. The first variant requires less hardware resources but it is almost 2 times slower then the second variant. It has its own instruction set that doesn’t depend upon data path width.
