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! InstructionFrequency Branches 19% Stores 11% Loads 22% 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.
