Abstract

An approach of the present disclosure includes an algorithm to encode an instruction set of a domain-specific processor automatically in an optimal way, and which yields area-effective hardware. Instruction operands and opcodes can be encoded separately or at the same time. Instructions are not encoded one by one but can be encoded in groups, and instructions are grouped automatically. The decoding logic of control signals for each group of instructions, such as register read enable and write enable, is fed to a logic minimizer to obtain an encoding constraint matrix, and the encoding of each instruction in each instruction group is done using an optimal state assignment method.
