AE250 Okwu Mmalite

AE250 bụ 32-bit RISC-V MCU usoro; E gosipụtara usoro ya na eserese 1-1.

Ihe osise 1-1 AE250 Structure Eserese

Dabere na bọọdụ mmepe Gowin FPGA, RISC-V AE250 MCU mmepe na usoro nbipu ka egosiri na eserese 1-2.

Ihe osise 1-2 Mmepe na nbibi Ọdịdị Sistemu

A na-ahazi mgbawa FPGA dị na bọọdụ mmepe ka AE250 MCU na-eji Gowin Programmer na PC, mgbe ejikọtara Debug Cable, ị nwere ike rụọ mmepe mmemme agbakwunyere yana debugging na ngwa AndeSight RDS v311.

Nkwadebe

Tupu iji Gowin FPGA na AE250 maka mmepe na nbipu, a ga-akwadorịrị ngwaọrụ ndị a:

1. Gowin GW2A usoro bọọdụ mmepe FPGA.
2. Ngwa nrụnye Gowin Software maka ịhazi na nbudata mgbawa FPGA.
3. AndeSight RDS v311 ngwungwu nwụnye maka ịmepụta na debugging mmemme agbakwunyere.
4. A na-eji USB debug maka nbudata na debugging mmemme agbakwunyere, na ndabara bụ AICE-MINI +; Ndị ọrụ kwesịrị ịzụrụ ya n'onwe ha.
