A. Menene kwatankwacin FPGA

A halin yanzu, guntuwar FPGA akan kasuwa galibi sun fito ne daga Xilinx da Altera, waɗanda suka mamaye sama da kashi 80% na rabon kasuwar FPGA.Sauran samfuran masana'antun FPGA galibi don takamaiman ƙayyadaddun aikace-aikace ne, alal misali, Actel galibi yana samar da tsarin FPGAs na anti-fuse don saduwa da ƙa'idodin aikace-aikacen jirgin sama da samfuran sararin samaniya.Wadannan sune samfuran wakilci na kamfanoni biyu, Altera da Xilinx.

Altera ta hankula samfurori

Na'urorin FPGA na Altera sun kasu kusan zuwa jeri uku: ɗaya shine jerin ƙananan ƙarancin Cyclone;na biyu shine babban jerin Stratix, kuma na uku shine jerin Arriva wanda za'a iya samun sauƙin ASICized tsakanin su biyun.
