Problem 24
A microprogrammed processor has the following parameters. Generating the starting address of the microroutine of an instruction takes \(2.1 \mathrm{~ns}\), and reading a microinstruction from the control store takes \(1.5 \mathrm{~ns}\). Performing an operation in the ALU requires a maximum of \(2.2 \mathrm{~ns}\), and access to the cache memory requires \(1.7 \mathrm{~ns}\). Assume that all instructions and data are in the cache. (a) Determine the minimum time needed for each of the steps in Figure \(5.26 .\) (b) Ignoring all other delays, what is the minimum clock cycle that can be used for this processor?
