The area of just the register file (even for rv32e) is higher area than the survivors of the 8 bit ucontrollers.

16 registers * 32 bits * 4 transistors / cell = 2k transistors just for storing the bits alone, and that's not including the decoding and read/write circuitry.

There is no need to do weird math, as we know the actual numbers.

6502 has 3510 transistors. SERV at CMOS occupies 2.1kGE.

SERV is smaller than 6502.

Gate Elements are multiple transistors.

And that count doesn't include SERV's register file.

So you're saying they'd end up in the same ballpark?

In that case, I'd rather have RISC-V's programming model.

More like about half the size. And probably running at about 10x the IPC of SERV.

Not true for SERV vs 6502.

SERV is smaller.

There’s also the cost of rewriting (yes, from assembler) all the existing code. And don’t forget QA.
