What does FPGA Stand For? <\/h2>\n\n\n\n

FPGAs, or field-programmable gate arrays, are more complex than typical integrated circuits. “FPGA” stands for field-programmable gate array. The higher number of I\/O pins on an FPGA requires forethought in design and layout and considerations in regard to system needs. <\/p>\n\n\n\n

These integrated circuits are more complex than your average IC. Reconfiguration is possible with FPGAs. An FPGA can function as a GPU (Graphics Processing Unit) then used later as a processor or video encoder. FPGA hardware and circuits allow many reconfigurations. This is not possible with standard chips.<\/p>\n\n\n\n

Reconfiguration occurs through gates or flip-flops, using configurable logic blocks, or CLBs. Just remember there are thousands of CLBs on a typical FPGA. <\/p>\n\n\n\n

What’s the difference between FPGAs and CPLDs? <\/h2>\n\n\n\n

A CPLD, or Complex Programmable Logic Device, is based on EEPROM architecture. It typically contains only a few thousand logic blocks and may have significantly fewer. FPGAs have up to 100K logic blocks and is a RAM-based digital logic chip. <\/p>\n\n\n\n

How to use FPGAs <\/h2>\n\n\n\n

Field programmable gate arrays are versatile. Some common uses include:<\/p>\n\n\n\n
