Here is -the description from that page: - - The MC68040 contains a subset of the floating-point hardware that is - implemented in the MC68881/882 devices and as such provides reduced yet - high performance on-chip floating-point support. Those applications that - require full compatibility with earlier members of the M68000 family - will need to provide emulation support fo r the un-implemented MC68040 - floating-point instructions. The M68040FPSP provides complete emulation - of the floating-point functionality available in the MC68881/882. - - The M68040FPSP is offered in source code form to allow integration into - existing systems to support either a kernel or library version of - floating-point support. The M68040FPSP operates in conjunction with the - on-chip MC68040 features to provide fast and full emulation. The kernel - version allows full emulation via a trap mechanism to allow full binary - compatibility and is fully reentrant. The library version is used to - eliminate the trap overhead in situation where re-compilation is - possible or desired. - -From this page one may download the original source code. Inline with -the first sentence of the second paragraph, we have integrated it with -RTEMS. - - |
