Fundamentals of memory

A collection of connected storage devices form the memory unit. It is a space to store data and instructions required for processing. Information is stored in a memory unit in the form of bits. There are two types of memory namely:

A processor uses a serial link to communicate with a keyboard for word processing. A typist using this keyboard can type at rates peaking at 120 words per minute, where a word is 6 characters (including spaces and punctuation). The characters will be transmitted from the keyboard in 8-bit ASCII with one stop bit and no parity. Only consider these and no special characters. The programmer writes setup and polling service routines based on a minimum baud rate, but then finds that the keyboard will only interface at 19.2 Kbaud. Will the polling service routine have to change? Why or why not? Baud Rates 300 600 1200 2400 4800 9600 19200

PROBLEM 1 For sorting a set of items, we can employ one of these famous algorithms, merge- sort, heapsort, quicksort, and shell-sort. We can program in both Java and Python, and we have the choice of using three different computers with different instruction set architectures: x86, ARM, and MIPS. Regarding microarchitecture, for x86 we have two choices, and for ARM and MIPS we have three choices for each of them. How many choices we have to run a sort algorithm? (Draw diagram).
Determine the effective CPI, MIPS rate, and execution time for this program. Consider two different machines, with two different instruction sets, both of which have a clock rate of 200 MHz. The following measurements are recorded on the two machines running a given set of benchmark programs: Instruction Count (millions) Instruction Type Machine A Arithmetic and logic Load and store Branch Others Machine A Arithmetic and logic Load and store Branch Others 8424 10 9824 Cycles per Instruction 1343 1243 4 a.

Suppose that we are developing a new version of the AMD Barcelona proces- sor with a 4 GHz clock rate. We have added some additional instructions to the instruction set in such a way that the number of instructions has been reduced by 15% from the values shown for each benchmark in Exercise 1.12. The execution times obtained are shown in the following table. a. Name Execution Time (seconds) Reference Time (seconds) bzip2 700 9650 SPECratio 13.7 1.13.2 [10] In general, these CPI values are larger than those obtained in previous exercises for the same benchmarks. This is due mainly to the clock rate used in both cases, 3 GHz and 4 GHz. Determine whether the increase in the CPI is similar to that of the clock rate. If they are dissimilar, why?
