Question

What does the RISC processor use to hold the data?

(a) flag register

(b) accumulator

(c) internal register

(d) stack register

I got this question in semester exam.

Question is taken from The mechanism of Interrupts in section Interrupts and Exceptions of Embedded Systems

Answer 1

Right answer is (c) internal register

To explain: The RISC processors uses special internal registers to hold data whereas the 80×86 and MC68000 family uses stack register to hold the data.
