- Actually, the MMU and FPU probably look very similar to those of other
- modern SPARC implementations (SPARC Reference MMU, for example);
- however, there may well be, for example, chip bugs in the microSPARC
- chip that require workarounds different from those required by the
- 7C601/7C602/7C605 or the SuperSPARC chip, and there are probably also
- some device driver changes needed for the "cloned" Z8530 and LANCE
- implementations that are claimed to be in the I/O chips on the Tsunami
- machines.
