ENGR 325 HOMEWORK 7 KEY FALL 2020. In this exercise we look at memory locality properties of matrix computation. The following code is written in C, where elements within the same row are stored contiguously. Assume each word is a 32-bit integer. (P&H 5.1, §5.1) for (I=0; I<8; I++) for (J=0; J<8000; J++) A[I][J]=B[I][0]+A[J][I]; a. How many 32-bit integers can be stored in a 16-byte cache block? b. References to which variables exhibit temporal locality? c. References to which...

1. (5) Consider the following instruction (P&H 4.1, §4.1): Instruction: AND Rd, Rs, Rt Interpretation: Reg[Rd] = Reg[Rs] AND Reg[Rt] a. What are the values of the control signals generated by the control in Figure 4.2 in the text for the above instruction? b. Which resources (blocks) perform a useful function for this instruction? c. Which resources (blocks) produce outputs, but their outputs are not used for this instruction? Which resources produce no outputs for this instruction? SOL...
