CPU Concept and Operation Principle The Central Processing Unit (CPU) is the core of computation and control in a computer, comprising an arithmetic unit, control unit, and registers. It performs fetch, decode, and execute cycles to process instructions.

CPU Instruction Set Concept and Classification CPU instruction sets are collections of commands that programs translate into for execution. They are classified into CISC (e.g., x86) and RISC (e.g., ARM, RISC‑V, MIPS, POWER, Alpha).

CPU Instruction Set Architecture Ecosystem CPUs based on x86 and ARM have good compatibility with downstream software and hardware, offering rich product options, while MIPS and Alpha are more niche, suited for high‑performance computing and embedded systems.

GPU Basic Concept The Graphics Processing Unit (GPU) is a specialized processor for image and graphics computation, commonly found in PCs, workstations, gaming consoles, and mobile devices.

GPU Working Principle and Structure GPUs generate 3D graphics, map them to pixels, and compute final colors through vertex processing, rasterization, texture mapping, pixel processing, and output. They use a stream‑parallel model for massive data parallelism.

GPU vs. CPU CPUs are low‑latency, control‑oriented, and excel at serial tasks, while GPUs are high‑throughput, parallel processors ideal for data‑intensive workloads such as AI training.

GPU Classification GPUs can be discrete (standalone graphics cards with dedicated memory) or integrated (shared with CPU memory), each with trade‑offs in performance, power consumption, and heat.

Storage Concept and Classification Computer storage includes various memory types and enterprise storage solutions, categorized into optical, semiconductor, and magnetic storage. Semiconductor storage splits into RAM (volatile) and ROM (non‑volatile), with DRAM and Flash dominating the market.

Basic Hardware: Integrated Machine The Xinchuang industry emphasizes autonomous, controllable hardware, with chips, integrated machines, operating systems, databases, and middleware as critical components.
