B.3 DSPM INSTRUCTIONS
A DSPM instruction execution starts with the CPU core writ-
ing to the CTL register. The execution time is counted from
state T3 of this transaction until all the results are ready,
either in the accumulator or in the coefficient RAM array.
The execution times, in clock cycles, for the various DSPM
instructions are listed in Table B-5.
It is assumed that External Hold Requests do not occur in
the middle of a VCMAD, VCMUL or VCMAC instruction.
The parameters n and w represent the number of elements
in the vector instruction and the number of wait states ap-
plied to each DSPM bus transaction respectively.
