Abstract
A technique for generating real-time events (control signal state changes) in a TDMA (Time Division Multiple Access) wireless digital communications system integrates the functions of a Burst Mode Controller (BMC) and a microcontroller onto a single chip, organizing them such that the BMC's 'frame program' (defining time slot and bit times for real-time events) shares an instruction ROM with the microcontroller. An automatic DMA mechanism within the BMC retrieves event definitions from within the frame program and effects the real-time events defined therein at the appropriate time. The technique permits any combination of signals to be changed at any time, while simultaneously reducing overall chip area, microcontroller overhead, power-consumption and cost.
