Understanding the Internal Structure and Principles of CPLD and FPGA

Programmable Logic Devices (PLDs) originated in the 1970s and are a new type of logic device developed based on Application-Specific Integrated Circuits (ASICs). They are the main hardware platform for digital system design today, characterized by being fully configurable and programmable by users through software to perform specific functions, and can be repeatedly erased and … Read more

Design and Verification of FPGA Programmable Logic Element Based on Sense-Switch pFLASH

Content Introduction Abstract: This paper proposes a programmable logic element (PLE) based on Sense-Switch type pFLASH technology. By programming the Sense-Switch type pFLASH, all three-input lookup table (LUT3) functions, some LUT4 functions, latch functions, and D flip-flop (DFF) functions with enable and reset capabilities are realized. Because the PLE uses a method called Combinational Operation … Read more
