64bits RISC-V cores? or a mix of 64bits/32bits RISC-V cores like on the bouffalo BL808? I cannot find anything about it.
This is chip is interesting as it is said the BL808 has a USB bug which forbid you to flash the bootrom over USB and you need to use the UART.
- IshKebab 4y agoSurely all 32 bit? I doubt anyone is going to use this with more than 2GB of RAM.
- sylware 4y agoMaybe not, since we would like to write 64bits RISC-V assembly code paths once and re-use them (like on the bouffalo). Then 64bits<->32bits ports would not happen, even though we know RISC-V 32bits<->64bits ISA port was made easy. This means seriously strong assembly code reuse.
