I can think of one valid use case for this unsolved by any other solution:
Lets say a company has an SoC board base product currently currently base on ARM. They want to eventually migrate to RISC-V based solution.
If a company has a product currently written to use ARM compiled code, but wants to transition to RISC-V (which isn’t ready yet), they could deploy this board which could run today’s ARM implementation, and it would be future-ready when the RISC-V implementation would be released without having to replace hardware.
Reminds me of my Commodore 128. You could boot it into 64 bit mode for legacy programs. I had exactly one C-128 game (which was a super complicated combat flight sim) so I only used it in C-64 mode.
The way the Sophgo SG2000 chip works, you can select to use either the 1 GHz RISC-V core or the 1 GHz ARM core, but you cannot use both at the same time.
Oh thats so strange. This is a really odd chip https://milkv.io/chips/sg2000
I thought it was maybe a FPGA with a switchable personality. But I can’t confirm my thought.
“I’d like a heterogeneous architecture sbc please”
They have played us for absolute fools.
But why?
