- fpsim.tar contains a floating-point simulator for 7th Edition, donated by
- Henry Spencer. Here are the details from the man page:
-
- This system provides for software emulation of floating-point
- instructions if floating-point hardware is not present. The
- kernel code in question simulates an FP11 floating-point
- processor by intercepting illegal-instruction traps and
- decoding and interpreting the floating-point opcodes.
-
- This simulator is derived from Bell's, which used signal(2)
- and was compiled into the user program. Mike Tilson of HCR
- thought of and did the original kernel-mode simulator;
- this improved variant by Henry Spencer.
