- The 68060 is the next-generation of architectural evolution of the 68000
- family. It's major enhancements (relative to the 68040) include:
- - Superscalar operation (int|int or int|float) w/ superpipelining
- - Branch Caching & Prediction (zero delay for predicted taken branches)
- - Larger Caches (8k icache & 8k dcache)
- - Full Hardware Instruction Execution (no microcode)
- - Fully static, 3.3v operation
- - Faster Floating Point
- - Configurable Bus Operation (full speed, half speed, ...)
- - Extended write buffering (4x 32bit fifo)
-
- It's major similarities include:
- - 100% User object code compatible (may need some simple OS hacks)
- - Compatible w/ existing support ASICs (superset of 040 package)
-
- That's the nickel tour.
