Quantifying Instruction Criticality

WebLast lecture, we saw encodings of MIPS instructions as 32-bit values. Register-to-register arithmetic instructions use the R-type format. —op is the instruction opcode, and func specifies a particular arithmetic operation (see textbook). —rs, rt and rd are source and destination registers.

Critical path of load instruction

WebThe critical path for a D-Format Load instruction consists of the following components: PC: The instruction starts by reading the PC register with a latency of 20ps. Register File: The instruction needs to read one register from the register file to get the memory address. This operation takes one cycle to complete. WebThis portion takes place for all instructions. The instruction is then decoded into control signals, as above, and executed by perfoming the associated register transfers on the data path. In addition, each …
