Field Programmable Get Array (FPGA)

FPGA are a very popular means for computing and prototyping. They provide great design flexibility, fast turnaround time and simpler design flow. These reasons, why FPGA are choose for design environment. Particularly, Altera DE2 board is used for the experiment platform. It hosts Cyclone II EP2C35 FPGA, SDRAM, SRAM, flash memory, SD memory card slot, 24-bit Audiocodec (WM8731), VGA codec, LEDs and other components. Cyclone II is a low-cost FPGA, which has a capacity of 33,216 logical-elements and 105 M4K RAM blocks. The components are using besides Cyclone II are: SDRAM and SRAM for storing data and instructions, audio codec for converting PCM samples to analog signals, and the SD card socket for input.
