Abstract: In the modular MAXQ architecture, a single-cycle 16x16 multiply-accumulate unit (MAC) is added to facilitate simple signal processing on the control processor. This article provides a DTMF example of how the MAC module in a typical MAXQ microcontroller can be used to solve real-world problems.
