Dedicated Multiplier Hardware (MAC) in PSoC 1
Performing multiplication can be tedious without dedicated hardware. Any dedicated hardware multiplier has finite resolution and applications may arise where more resolution is required. The application note below from dave van ess describes the techniques that enable the PSoC 1 MCU to quickly multiply multiple-byte-operands and give a full resolution output.

The Application note discusses different ways to perform complex multiplications and benchmarks CPU cycles and memory used in each case. This will be definitely useful for your applications where multiplication is involved.
