Study Notes
RISC
- Reduced Instruction Set Computers (RISC) have a small instruction set
- Instructions are approximately one line of machine code and take one clock cycle to complete
- Assembly code example of multiplying two numbers X and Y involves loading X into register R1, loading Y into R2, multiplying R1 by R2, and storing the result in R1
- Compilers need more work to translate high-level code to machine code
- Requires more RAM to store code
- Pipelining is possible because each instruction takes one clock cycle
CISC
- Complex Instruction Set Computers (CISC) has a large instruction set
- Aims to complete tasks in as few lines of assembly code as possible
- These instructions are built into the hardware
- Once standard, RISC designs replaced them over time
- Now predominately used in microcontrollers and embedded systems
- Assembly code example of multiplying two numbers A and B involves a single instruction: MULT A, B
- Compilers need to perform less to translate high-level code to machine code
- Requires less RAM because code is shorter
- Many specialized instructions are made, but only a few are typically used
Multi-Core and Parallel Systems
- Multi-core CPUs have multiple independent cores
- Each core can complete instructions separately, resulting in higher performance
- Parallel systems accomplish a similar task without requiring multiple cores by using threading
- Multi-core systems generally perform better on larger projects than parallel systems
Graphics Processing Unit (GPU)
- Unlike CPUs, GPUs contain multiple independent processors
- Processors work in parallel making it very efficient at completing repetitive tasks such as image processing and machine learning
- GPUs are a type of co-processor which supplement the activities of the primary processor

Description
Comparing RISC (Reduced Instruction Set Computing) and CISC (Complex Instruction Set Computing) architectures. RISC uses a smaller instruction set with single-cycle instructions, while CISC aims to complete tasks with fewer lines of assembly code. RISC is suitable for pipelining, whereas CISC is used in microcontrollers.
