FPGA & CPLD Components: A Designer's Guide
Understanding programmable chip architecture is critical for effective FPGA and CPLD design. Standard building elements feature Configurable Logic Blocks (CLBs) or Functionally Programmable Logic Block (FPLBs) which house lookup registers and flip-flops, coupled with programmable interconnect resources. CPLDs generally use sum-of-products architecture arranged in configurable array blocks, while FPGAs offer a more granular structure with many smaller CLBs. Thorough consideration of these basic components during a development phase results to stable and optimized implementations.
