Embedded - FPGAs (Field Programmable Gate Array)

1. Overview

Field Programmable Gate Arrays (FPGAs) are reconfigurable semiconductor devices containing programmable logic blocks and interconnects. They enable hardware-level customization for specific computational tasks, offering flexibility unmatched by ASICs or microprocessors. In modern technology, FPGAs are critical for applications requiring parallel processing, low-latency execution, and real-time adaptability, such as AI acceleration, 5G communications, and industrial automation.

2. Main Types and Functional Classification

Type	Functional Features	Application Examples
Low-Cost FPGAs	Optimized for budget-sensitive applications with minimal logic density	Consumer electronics, IoT edge devices
High-Performance FPGAs	Advanced DSP blocks, high-speed transceivers (>100 Gbps)	Data centers, radar systems
SoC FPGAs	Integrated ARM processors with FPGA fabric	Industrial control, medical imaging
MPSoC FPGAs	Multi-core processors with AI acceleration engines	Autonomous vehicles, 5G base stations

3. Architecture and Components

A typical FPGA consists of:

Logic Units: Configurable Lookup Tables (LUTs) and flip-flops for implementing Boolean functions
Routing Resources: Programmable interconnects for signal pathways
I/O Interfaces: Standardized protocols (PCIe, DDR4, Ethernet)
