  • Uyilo lweBhodi yeFPGA PCB ephuculweyo

Inkcazelo emfutshane:

FPGA ibhodi pcb.Ibhodi ye-iCore4 engundoqo yolawulo lwemizi-mveliso yibhodi yesine yesizukulwana se-iCore esinebhodi engundoqo esungulwe yinkampani;ngenxa ye-ARM yayo ekhethekileyo + FPGA “ubukhulu obunye-ilingana-bonke” ubume obubini obungundoqo, inokusetyenziswa kumlinganiselo wovavanyo oluninzi kunye nemimandla yolawulo.Xa i-iCore4 isetyenziswe kwi-core of the product, i-"ARM" engundoqo isebenza njengendima ye-CPU (inokuthiwa "indima" yokubulawa kwe-serial), ejongene nokuphunyezwa komsebenzi, ukuqhutyelwa kwesiganeko, kunye nemisebenzi ye-interface.Njengendima "yesixhobo sokuqiqa" (okanye "indima ehambelanayo" yokwenziwa), undoqo we-"FPGA" unoxanduva lwemisebenzi efana nokucubungula ngokuhambelanayo, ukusetyenzwa kwexesha lokwenyani, kunye nolawulo lwengqiqo.Iicores ezimbini "ARM" kunye ne "FPGA" zinxibelelana zisebenzisa i-16-bit parallel bus.I-bandwidth ephezulu kunye nokulula kokusetyenziswa kwebhasi ehambelanayo iqinisekisa ukulungelelaniswa kunye nokusebenza kwexesha langempela lokutshintshiselana kwedatha phakathi kwee-cores ezimbini, okwenza i-cores ezimbini "ziphonswe kwintambo enye" ​​ukujamelana nemisebenzi ekhulayo yokuvavanya kunye nokulinganisa kunye ngokuzenzekelayo. iimveliso zolawulo , Iimfuno zokusebenza.
