a. (1 pt) Define the stored program concept.

Consider a proposed instruction inc. This instruction treats a word in memory as an integer and adds 1 to it. For example, inc 8(t1) would add 1 to the value at the address t1+8. (You could think of this as adding one to the third element of the array starting at t1.) b. (1 pt) If inc were to be added to the RISC-V instruction set, what is the most appropriate instruction format? Explain in one sentence.

c. (2 pts) What is the shortest sequence of RISC-V instructions that performs the same operation as inc 8(t1)?

d. (1 pt) inc should almost certainly not be added to the instruction set. In one sentence, why not?
