7. Register Transfer Language (RTL) Description Consider the One-bus organization of the MIPS processor. For each of the MIPS assembly language instruction given below . Specify the micro-operations needed to implement the instruction. Complete a table with the following header for each instruction: Clock cycle RTL (micro-operation) Identify the control signals that must be asserted for each micro-operation. Control signals Use a minimum number of clock cycles Assume that each instruction has been fetched from program memory and is in the IR (a) subtract (b) add immediate (c) store word
