LCA=Logic Cell Array. The logic cell array includes three parts: CLB (Configurable Logic Block), IOB (Input Output Block) and Interconnect.
FPGA adopts the concept of LCA (Logic Cell Array), which includes three parts: Configurable Logic Block (CLB), IOB (Input Output Block), and Interconnect. Field programmable gate array (FPGA) is a programmable device. Compared with traditional logic circuits and gate arrays (such as PAL, GAL and CPLD devices), FPGA has a different structure. FPGA uses a small lookup table (16×1RAM) to implement combinational logic, and each lookup table is connected to a D flip-flop The input terminal, the trigger and then drive other logic circuits or drive I/O, thereby forming a basic logic unit module that can realize combinational logic functions and sequential logic functions. These modules are connected or connected to each other by metal wires To the I/O module. FPGA logic is realized by loading programming data to the internal static storage unit. The value stored in the memory unit determines the logic function of the logic unit and the connection between modules or between modules and I/O, and finally determines The logic function of the logic unit and the connection between the modules or between the modules and the I/O ultimately determine the functions that the FPGA can achieve, and the FPGA allows unlimited programming.
