A RISC processor has 8 global registers and 10 register windows. Each window has 4 input registers, 8 local registers, and 4 output registers. How many total registers are in this CPU? (Hint: Remember, due to the circular nature of the windows, the output registers of the last window are shared as the input registers of the first window.).

2. Indicate whether each of the following applies to CISC or RISC by placing either a C (for CISC) or an R (for RISC) in the blank. _____ Simple instructions averaging one clock cycle to execute. _____ Single register set. _____ Complexity is in the compiler. _____ Highly pipelined. _____ Any instruction can reference memory. _____ Instructions are interpreted by the microprogram. _____ Fixed length, easily decoded instruction format. _____ Highly specialized, infrequently used instructions. _____ Use of overlapping register windows. _____ Relatively few addressing modes.
