Notes with worthy tutorials
The architecture of a modern CPU (Central Processing Unit) is designed to efficiently execute instructions and process data.
A computer system is composed of several key components that work together to process and manage data. These components can be broadly categorized into hardware and software, with hardware referring to the physical parts of the computer and software referring to the programs that run on the hardware. Here are the primary components:
Instruction-Level Parallelism (ILP) is a crucial concept in CPU design aimed at improving performance by executing multiple instructions simultaneously or overlapping their execution. ILP allows CPUs to exploit available instruction-level parallelism within a program to increase throughput and reduce execution time.
CPU caches serve as high-speed storage units that store frequently accessed data and instructions to reduce the latency of memory access and improve overall CPU performance. Caches are designed to exploit the principle of locality, which states that programs tend to access a relatively small subset of data and instructions repeatedly within a short period of time. By storing this frequently accessed data and instructions in caches, CPUs can minimize the time spent waiting for data to be fetched from slower main memory.
RISC (Reduced Instruction Set Computing) and CISC (Complex Instruction Set Computing) architectures are two distinct approaches to CPU design, each with its own characteristics, advantages, and disadvantages.
The CPU (Central Processing Unit) acts as the computer’s brain, managing instruction execution and conducting essential calculations for system functionality. It coordinates data processing, executes programs, and interacts with other components to ensure seamless operation.
