FPGA & DSP
The historical roots of FPGAs are in complex programmable logic devices (CPLDs) of the early to mid 1980s. Ross Freeman, Xilinx co-founder, invented the field programmable gate array in 1984. CPLDs and FPGAs include a relatively large number of programmable logic elements. CPLD logic gate densities range from the equivalent of several thousand to tens of thousands of logic gates, while FPGAs typically range from tens of thousands to several million.

Applications of FPGAs include DSP, software-defined radio, aerospace and defense systems, ASIC prototyping, medical imaging, computer vision, speech recognition, cryptography, bioinformatics, computer hardware emulation and a growing range of other areas. FPGAs originally began as competitors to CPLDs and competed in a similar space, that of glue logic for PCBs. As their size, capabilities, and speed increased, they began to take over larger and larger functions to the state where some are now marketed as full systems on chips (SOC).

FPGAs especially find applications in any area or algorithm that can make use of the massive parallelism offered by their architecture. One such area is code breaking, in particular brute-force attack, of cryptographic algorithms.
