FPGA: Apollo-Core-Update GOLD 2.17 "Bronto"
The Apollo-Core is a FPGA reimplementation of the m68k series produced by Motorola which also provides a separate graphics driver called SAGA. The core is used in the Vampire accelerator boards 600 V2, 500 V2+ and 1200 V2. Changes:
- Card supports now to run in one of 4 different speed mode. This allows for run old games e.g. in speed of A500 or A1200, to improve running old games that have problems running on faster CPUs.
- Support for new instruction EXTUB.L
This instruction is very useful for type conversion.
It is used by some GCC versions.
Supporting it does improve code density and improves performance.
- Support for new instruction EXTUW.L
This instruction is very useful for type conversion.
It is used by some GCC versions.
Supporting it does improve code density and improves performance.
- Support for enhanced instructions
BRA.s+ BSR.s+ BCC.s+
This instruction is supported by some compilers and assemblers.
This instruction improves code density and improves performance.
- Hardware optimized version of FPU instruction FDBcc.w
- Hardware optimized version of FPU instruction FDBcc.l
- several FPU Performance optimizations ported from V4-FPU to V2
