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...

(5) What is 5ED4 – 07A4 when these values represent unsigned 16-bit hexadecimal numbers? The result should be written in hexadecimal. Show your work. (P&H 3.1, §3.2) SOLUTION: 5ED4 - 07A4 0x5730 2. (5) What is 5ED4 – 07A4 when these values represent signed 16-bit hexadecimal numbers stored in sign-magnitude format? The result should be written in hexadecimal. Show your work. (P&H 3.2, §3.2) SOLUTION: If both are signed hex numbers in sign-magnitude format (MSB = sign), the resul...
