Problems with Superscalar approach

Problems with Superscalar approach. Limits to conventional exploitation of ILP: 1) Pipelined clock rate : Each increase in clock rate has corresponding CPI increase (branches, other hazards). (pipeline latency)

Problems with Superscalar approach

Problems with Superscalar approach. Limits to conventional exploitation of ILP: 1) Pipelined clock rate : Increasing clock rate requires deeper pipelines with longer pipeline latency which increases the CPI increase (longer branch penalty , other hazards).
