Study Notes

FPGA is a programmable integrated circuit used for digital logic circuits implementation
FPGAs are used in digital signal processing, embedded systems, and computer networking
Consists of a large number of programmable logic elements (PLEs) and programmable interconnects (PICs)
PLEs are made up of look-up tables (LUTs) and flip-flops, while PICs facilitate signal routing between PLEs
FPGAs are highly flexible, reprogrammable, and suitable for applications requiring frequent changes or upgrades
Offers high parallelism, beneficial for high-speed signal processing and image processing
Popular in embedded systems due to cost-effectiveness and power efficiency compared to ASICs in low-volume and high-volume production.
