Minimize FPGA power consumption

What is an ASIC?
An application-specific integrated circuit (ASIC) is an IC that is customized for a specific application (end product or a closely related family of end products), such as a chip which is designed to run a cellular handset.

What is an FPGA?
A Field Programmable Gate Array (FPGA) is a type of gate array that is programmed in the field rather than in a semiconductor fab.

What are CPLDs?
A complex programmable logic device (CPLD) is a programmable logic device with complexity between that of PALs and FPGAs, and architectural features of both. It is made up of several simple PLDs (SPLDs) with a programmable switching matrix in between the logic blocks. CPLDs typically use EEPROM, flash memory or SRAM to hold the logic design interconnections.
