MaverickCrunchTM
Various MaverickCrunch errata share common features. The individual descriptions will refer to these
common features.
1) For several errata, an instruction appears in the coprocessor pipeline, but does not execute for one of
the following reasons:
- It fails its condition code check.
- A branch is taken and it is one of the two instructions in the branch delay slot.
- An exception occurs.
- An interrupt occurs.
2) For several errata, the coprocessor must be either operating in serialized mode or not be operating in
serialized mode. The coprocessor is operating in serialized mode if and only if both:
- At least one exception type is enabled by setting one of the following bits in the DSPSC: IXE, UFE,
OFE, or IOE.
- Serialization is not specifically disabled by setting the AEXC bit in the DSPSC.
3) For several errata, an instruction must update an accumulator. These include all of the following:
- Moves to accumulators: cfmva32, cfmva64, cfmval32, cfmvam32, cfmvah32.
- Arithmetic into accumulators: cfmadd32, cfmadda32, cfmsub32, cfmsuba32.
4) For several errata, an instruction must be any two-word coprocessor load or store. These include cfldr64,
cfldrd, cfstr64, and cfstrd.
The following table summarizes MaverickCrunch errata.
Several of the errata are sensitive to certain coprocessor instructions appearing early in an interrupt or
exception handler. To avoid seeing any errata due to such instructions, insure that no coprocessor
instructions appear in the instruction stream within the first seven instructions after an interrupt or exception.
Note that, typically, the first three instructions in this stream would be a branch in the jump table followed by
the two instructions in the branch delay slot.
