COMPSCI2208 - Introduction To Computer Organization And Architecture

Lecture 1.1 Computer Architecture Instruction set Architecture (ISA) ISA has to do with the programming level, essentially Machine Language It provides instructions to the processor ISA has to do with three main computer responsibilities amongst others Registers Sets Instruction Sets Addressing Modes Computer Organization Whereas the architecture describes what a computer does, the organization or microarchitecture is how the ISA is implemented (how it's done). Architecture and organization are

Introduction to Assembly Question 1 - Definitions of Registers a. PC is the program counter and its job is to point to the location in memory that holds the next instruction to be executed. b. MAR is the memory address register, and it stores the address of the memory currently being accessed by a read/write operation c. MBR is the memory buffer register, and it stores the data that was just read from memory or is just about to be written to memory. d. IR is the instruction register, and it hold

Conversion from Any Base System to Decimal This is how you could convert from any base system to decimal, including radix points EXAMPLE - BASE-3 TO DECIMAL, STANDARD METHOD Convert If this method is a bit slow for your liking, try this - EXAMPLE 2 - ALTERNATE METHOD Convert Conversion from Decimal to Any Base System DIVISION METHOD (INTEGER NUMBERS) REPEAT - Divide the quotient (decimal number) by the new base to get - A new quotient (whole number) A remainder Remainder is the least

2's Complement Base Principles There are a few basic principles that are important to understanding 2's complement arithmetic. Anytime arithmetic with a negative number is involved, use 2's complement to convert that number to a positive value and simply add This would be cases such as - Overflow occurs when an illogical answer is found Overflow is when a result extends past the domain of the solutions (result is too large or too negative in respect to possible numbers available given the nu
