FPGA pcb bhodhi.iCore4 dual-core industry control board ndiyo yechina-chizvarwa iCore series dual-core board yakatangwa nekambani;nekuda kweiyo yakasarudzika ARM + FPGA "imwe-saizi-inokodzera-zvese" maviri-musimboti chimiro, inogona kushandiswa mune yakawanda bvunzo kuyerwa uye kutonga minda.Kana iCore4 ichishandiswa pakati pechigadzirwa, iyo "ARM" musimboti inoita seCPU basa (inogona zvakare kunzi ibasa re "serial" kuuraya), rinoita basa rekuita, kugadzirisa chiitiko, uye interface mabasa.Sebasa re "logic device" (kana kuti "parallel" execution role), "FPGA" musimboti une basa rekuita senge parallel processing, real-time processing, uye logic management.Iwo maviri cores "ARM" uye "FPGA" anotaurirana achishandisa 16-bit parallel bhazi.Iyo yakakwira bandwidth uye nyore kwekushandisa bhazi rakafanana inovimbisa kuve nyore uye chaiyo-nguva kuita kwekuchinjana kwedata pakati pemacores maviri, zvichiita kuti macores maviri "akamonyoroka kuita tambo imwe" kutarisana nekuwedzera kwemabasa ekuyedza uye kuyerwa uye otomatiki. control products , Performance zvinodiwa.
