Webinstruction set supporting just the following operations. Today we’ll build a single-cycle implementation of this instruction set. — All instructions will execute in the same amount of time; this will determine the clock cycle time for our performance equations. — We’ll explain the datapath first, and then make the control unit. Web-cycle time limited by longest instruction (lw)-two adders/ALUs and two memories Multi-cycle microarchitecture: + higher clock speed + simpler instructions run faster + reuse expensive hardware on multiple cycles-sequencing overhead paid many times Same design steps: datapath & control

WebWith a single-cycle datapath, each instruction would require 8ns. But if we could execute instructions as fast as possible, the average time per instruction for gcc would be: (48% x 6ns) + (22% x 8ns) + (11% x 7ns) + (19% x 5ns) = 6.36ns The single-cycle datapath is about 1.26 times slower!

WebDatapath and Control . Datapath: Memory, registers, adders, ALU, and communication buses. Each step (fetch, decode, execute, save result) requires communication (data transfer) paths between memory, registers and ALU. Control: Datapath for each step is set up by control signals that set up dataflow directions on communication buses and Webper instruction, which fixes some shortcomings of the 1-cycle implementation. • Faster instructions (R-type) are not held back by the slower instructions (lw, sw) • The clock cycle time can be decreased, i.e. faster clock can be used • Eventually simplifies the implementation of pipelining, the universal speed-up technique.
