72 bits wide. If the accumulator saturation mode is disabled (the default), the accumulator bit
fields are assigned as below for a 2’s complement integer.
If the saturation mode 1.63 is selected, the bit field assignments are:
If the saturation mode 1.31 is selected, the bit field assignments are:
If the saturation mode 2.62 is selected, the bit field assignments are:
3.1.6 Comparisons
The Crunch co-processor provides four compare operations:
CFCMP32 - 32-bit integer
CFCMP64 - 64-bit integer
CFCMPS - single floating point
CFCMPD - double floating point
The DSPSC register bit UINT affects the operation of integer comparisons. If clear, integers
are treated as signed values, and if set, they are treated as unsigned. DSPSC.UINT has no
effect on floating point comparisons.
All compare operations update both the FCC[1:0] bits in the DSPSC register and an ARM
register. Though any of the ARM general purpose registers r0 through r14 may be specified
as the destination, specifying r15 actually updates the CPSR flag bits NZCV. This permits the
