Consider the following MIPS assembly language instructions: addi $1, $2, 100 swr $1, 0($2): addi $rt, $rs, immediate # add immediate swr $rt, immedi ate ($rs) # store word write register These instructions are I-format instructions similar to the load word and store word instructions. The addi and swr instructions store a computed value to the destina- tion register $rt. The instructions do not require any physical hardware changes to the datapath. The effect of each instruction is given below....

6. Memory Access Time [15 points] Consider a MIPS processor that includes a cache, a main memory, and a hard drive. Access times of cache memory, main memory, and hard drive are 5 ns, 200 ns, and 1000 ns, respectively. Assume that cache memory is divided into instruction cache and data cache. Assume that data cache has a 90% hit rate. Assume that main memory has a 98% hit rate and hard drive is perfect (it has a 100% hit...

HELP ME WITH TRUE / FALSE and Multiple choices. Fixed-width instructions make it difficult to decode because the number of bytes each instruction is using can change. True False A register is incremented by either a byte or a word to advance to the next element in an array with Indexed Addressing. True False The "la" instruction is an example of a pseudo-instruction. True False PC-relative addressing uses the program counter as the base address. True False PC-relative addressing uses...

Exercise 8.16 You are building a computer with a hierarchical memory systenm that consists of separate instruction and data caches followed by main memory. You are using the ARM multicycle processor from Figure 7.30 running at 1 GHz (a) Suppose the instruction cache is perfect (i.e., always hits) but the data cache has a 5% miss rate. On a cache miss, the processor stalls for 60 ns to access main memory, then resumes normal operation. Taking cache misses into account,...

FIRST ACTIVITY (100/100) RANDOM MEMORY ACCESS (RAM) EMULATOR: The following dircuit is a memory with 8 addresses, each address holding a 4-bit data. The memory positions are implemented by 4-bit registers. The resetn (active low) and clock signals are shared by all the registers. Data is written onto (or read from) one of the registers. wE rd 0 2 Memory Write (wr-rd = 1): The 4-bit input Din is written into one register. The address [2..0 signal selects...

Questions1. The function L is defined as L(1) = 2,L(2) = 1,L(3) = 3,L(4) = 4 and for n ≥ 4,L(n + 1) = L(n) + L(n − 1) + L(n − 2)L(n − 3)i.e., the (n + 1)-th value is given by the sum of the n-th, n − 1-th and n − 2-th values divided by the n − 3-th value.(a) Write an assembly program for computing the k-th value L(k), where k is an integer bigger than...
