Half-baked Benchmark

October 15, 2017

I jury-rigged a dhrystone benchmark for the 1802 at 10MHz. It clocked about 150 dhrystones per second compared to my best previous result of 81/sec for an 1806 at 4MHz. For comparison, a Z80 at 4MHz can do 300/sec but with a much better compiler.

Biggest problem in adapting it was to have the AVR be fast enough to grab the report output from the 1802. I had to put a ton of nops in the 1802 print routines. Not sure if this affected timing.
