Central processing unit (CPU)

Multiplier-accumulator unit (MAC)
The MAC coprocessor is a specialized coprocessor added to the ST10 CPU Core in order to
improve the performances of the ST10 Family in signal processing algorithms.
The standard ST10 CPU has been modified to include new addressing capabilities which
enable the CPU to supply the new coprocessor with up to 2 operands per instruction cycle.
This new coprocessor (so-called MAC) contains a fast multiply-accumulate unit and a repeat
unit.
The coprocessor instructions extend the ST10 CPU instruction set with multiply, multiply-
accumulate, 32-bit signed arithmetic operations.
