6.1 Hardware Multiplier Module Support
The hardware multiplier module expands the capabilities of the MSP430
family without changing the basic architecture. Multiplication is possible for:
- 16
×
16 bits
- 16
×
8 bits
- 8

16 bits
- 8
×
8 bits
The hardware multiplier module supports four types of multiplication: unsigned
multiplication (MPY), signed multiplication (MPYS), unsigned multiplication
with accumulation (MAC), and signed multiplication with accumulation
(MACS). Figure 6–1 shows how the hardware multiplier module interfaces
with the bus system to support multiplication operations.
