WebApr 3, 2024 · And so finally I have four ALU slices in the architecture of the project but I can't compile because I can't seem to figure out a way of updating the opcode logic vector in the alu slice component such that it is replicated across all of the separate slices performing the appropriate operation between each of the four bits. WebNot all the 39 bits need to be part of the opcode. In general the bits of the opcode fields are calculated from the number of opcodes, which has not been given. Those 39 bits can be used or reserved for future use. For example, 3 bits could be used to specify a byte in each word (thereby extending the address bits).
