b80fda4280 The IBM 386/486 cpu's are based on modified Intel 386 designs and, as such, should behave like the them on the x86 flag ops. 2022-07-15 12:34:41 +02:00

1ac46d792f Fixed the 8514/A to VGA soft reset and made the vga_on variable a global one to make sure it's used by the soft reset. 
Updated copyright holder that was accidentally reverted while committing the IBM 8514/A source files.

eab711a4ed x87_ops_*.h: emulate fpu/iu concurrency for each fpu instruction 2022-01-29 07:38:53 -08:00
linear cannon
04c89959f8 adjust CLOCK_CYCLES and related macros to handle fpu/iu concurrency 
add CLOCK_CYCLES_FPU, which does exactly what CLOCK_CYCLES already did.

add CONCURRENCY_CYCLES, which sets fpu_cycles, which is the number of
available concurrent execution cycles that the integer unit can do
"free" work in while the fpu is executing.

adjust CLOCK_CYCLES so that if there are fpu_cycles, the cycle count is
subtracted from fpu_cycles instead of cycles, emulating the behavior of
these concurrent cycles being "free" as on real hardware.
