Embedded - FPGAs (Field Programmable Gate Array) with Microcontrollers

1. Overview

Embedded Field Programmable Gate Arrays (FPGAs) with microcontrollers represent a hybrid architecture combining programmable logic fabric with hard processor cores. This integration enables parallel processing capabilities of FPGAs with the sequential processing efficiency of microcontrollers. Modern devices often implement ARM Cortex-A/R series cores alongside programmable logic, creating System-on-Chip (SoC) solutions. These ICs are critical in applications requiring real-time processing, hardware acceleration, and flexible I/O interfacing, such as industrial automation, automotive systems, and communication infrastructure.
