Question

Which of the following is true about register windowing?

(a) chips expose 32 registers to programmer

(b) puts demands on multiplexers

(c) puts enormous demands on register ports

(d) all of the mentioned

I got this question by my college director while I was bunking the class.

My doubt is from Hybrid Architecture -RISC and CISC Convergence, Advantages of RISC, Design Issues of RISC Processors -2 in chapter RISC Architecture of Microprocessor

Answer 1

Right answer is (d) all of the mentioned

Best explanation: The register windowing involves a mechanism where the chips expose 32 registers to the programmer at any one time. It puts enormous demands on multiplexers and register ports to make any physical register appear to be any logical register.
