Methods for executing a computer instruction and apparatuses using the same
The invention introduces a method for executing a computer instruction, which contains at least the following steps: decoding the computer instruction to generate a micro-instruction at least containing an opcode (operation code) and a packed operand, where the packed operand contains all n input parameters corresponding to the computer instruction; generating n addresses of the n input parameters according to the opcode and the packed operand; and reading n approximations corresponding to the n addresses from a lookup table.
