The EightThirtyTwo ISA – Part 12 – 2019-12-07

Since my last post I’ve put some further work into the EightThirtyTwo vbcc backend, and I now have it working well enough to compile a working Dhrystone benchmark. That’s the good news. Here’s the bad news:

User time: 1541
Microseconds for one run through Dhrystone: 61 
Dhrystones per Second:                      16223 
VAX MIPS rating * 1000 = 9231 

OK, that’s not terrible, but it’s not as high as I was hoping.
