WebJun 26, 2012 · What is expanding opcode? A code that leaves a spare bit to indicate that if that bit is set, consider this byte and the next byte to be defining the entire code. WebExpanding opcodes represent a compromise between the need for a rich set of opcodes and the desire to have short opcodes, and thus short instructions. black toe

When the opcode is short, a lot of bits are left to … WebApr 27, 2024 · That leaves 6 bits left over for the opcode. That means that we should have 2^6 = 64 opcodes which means we have 64 - 8 = 56 R-type opcodes. Another way to look at this problem is to say that an R-type instruction needs 12 bits for two register specifications. This leaves 4 bits for the opcode. Hence, there are 16 R-type opcodes. foxeer hs1177
