Answer #1

A) Stack data structure is used by the machine code program placed in the instruction memory of a fixed-length instruction representation processor.

B) ISA stands for Instruction set architecture. It provides various instructions such as Data handling and memory instruction, arithmetic and logical instruction, Control flow instruction and co-processor instruction, Complex instruction (For ex. SIMD, CISC).Instruction is used to perform various operations on multiple pieces of data at the same time. It has the ability of manipulating large vectors and matrices in minimal time. It also allows the easy parallelization of the algorithm which is commonly used in sound, image and video processing. Thus, various ISA has been brought to various market under the trade. For example, MMX and 3DNow!.

A digital computer has a memory unit with 32 bits per word. The instruction set consists of 147 different operations. All instructions have an operation code part (opcode) and two address fields: one for a memory address and one for a register address. This particular system includes eight general-purpose, user-addressable registers. Registers may be loaded directly from memory, and memory may be updated directly from the registers. Direct memory-to-memory data movement operations are not supported. Each instruction stored in one...

Lists are members of a general category of abstract data types (ADTs) called containers (i.e., objects whose purpose is to hold other objects). A list is a collection of items having the following defining characteristics: Homogeneity: All the items are of the same type. Linearity: Each item has a unique predecessor (except the first) and a unique successor (except the last). Variable Length: The number of items can vary over time. Order: Items may be ordered (i.e., as in a...

-Data Structure in C++ (Review for C++) -using vector and class In this assignment you’re going to build a simple “register machine”, a kind of minimal computer that only supports storing a fixed number of values (i.e., no randomly-accessible “main memory”). Your machine will consist of an input loop that reads lines of input from the user and then executes them, stopping when the user quits (by executing the stop command). Each line of input consists of a command followed...

Studies are often done by pharmaceutical companies to determine the effectiveness of a treatment program. Suppose that a new AIDS antibody drug is currently under study. It is given to patients once the AIDS symptoms have revealed themselves. Of interest is the average length of time in months patients live once starting the treatment. Two researchers each follow a different set of 50 AIDS patients from the start of treatment until their deaths. a. What is the population of this...
