Fenestra6502

[hatsugai]

I wrote a code generator of CCLV for 6502 (W65C02S) and measured the execution time of fib and tarai.

Thanks hatsugai! This feels like valuable information, even though I can't make use of it myself.

Thank you for the information.

I was surprised to see the deep discussions.

I seem the tarai function is suitable for this kind of benchmarks, especially for measuring the performance of procedure/function calls.

Dr. Ikuo Takeuchi, the inventor of the tarai function, is famous as a Lisp hacker (one of the developper of TAO and NUE). It is said that tak version is McCarthy's mistake.

By the way, I made a MC6800 SBC (MC68B00, 2MHz) to compare the performance with Fenestra 6502 and others. Does anybody know if there is a C compiler for MC6800? If not, I will write a code generator of CCLV for MC6800.

There are three cross C compilers for the MC6800, all of which are maintained and require Fuzix-Bintools.
