6. FPGA Architecture and Capabilities
Field-Programmable Gate Arrays (FPGAs) are versatile digital devices that provide the ability to implement and reconfigure custom digital circuits. The chapter outlines FPGAs' architecture, including key components like logic blocks, programmable interconnects, I/O blocks, and the design flow for implementing digital systems using VHDL or Verilog. Additionally, it emphasizes FPGA capabilities such as reconfigurability, high parallelism, performance, low power consumption, and the integration of embedded systems.
