F28335 and FPU MAC

Bernhard Bauer said:

Hi,

a efficient MAC needs two parallel MOVs. Is the F28335 FPU capable of this?

Thanks

Two operands to the MACF32 instruction point to the source location and read the contents as part of the operation.   This can be done without stalling if the operands and source are all in seperate physical memory blocks.  These pointers automatically increment when MACF32 is combined with the RPT || instruction.

For more details, please see the documentation for MACF32 R7H, R3H, mem32, *XAR7++ in the FPU reference guide: www.ti.com/lit/sprueo2
