Study Notes
Introduction
- Computer organization encompasses the physical aspects of computer systems, such as circuit design, control signals, and memory types.
- Computer architecture focuses on the logical aspects of system implementation, such as instruction sets, instruction formats, data types, and addressing modes.
Computer Systems
- The distinction between computer organization and computer architecture is not always clear.
- The Principle of Equivalence of Hardware and Software states that any task performed by software can also be performed by hardware, and vice versa, assuming speed is not a concern.
Parallel Computing
- Parallel processing allows computers to work on subparts of a problem simultaneously.
- Multicore processors have two or more processor cores on a single die, each with its own ALU and registers but sharing memory and other resources.
- Multithreading allows applications to spread processes, called threads, across multiple processors for increased throughput.
Data Representation in Computer Systems
- One's complement representation is a method for representing signed integers where a negative number is represented by inverting all the bits of its positive counterpart.
- Two's complement representation is a method for representing signed integers where the negative representation is 1 plus the one's complement
- Excess-M representation is a method for representing signed integers where the value is represented as a positive integer offset by a constant value, M.
Floating-Point Representation
- The IEEE-754 floating-point standard is a widely used format for representing real numbers.
- In this format, numbers are represented as a sign bit, an exponent, and a significand.
- Exponent values of 255 in single precision and 2047 in double precision represent special values, such as infinity and NaN (not a number).
Error Detection and Correction
- CRC (Cyclic Redundancy Check) is a commonly used method for detecting errors in data transmission.
- CRC utilizes modulo 2 division to calculate a checksum value that can be used to verify the integrity of data.
