Abstract
A multi-tasking, dynamically controlled micro-sequencer for use in a TDMA communication system is described. Rather than the output of the sequencer being solely a linear sequence of instructions in a microcode RAM, the output of the sequencer is augmented by an output of finite state machines (FSMs) providing a sequence of control codes. The FSMs provide control signals for building a slot in accordance with a specific protocol. The sequencer core provides enabling signals to the FSMs to enable the proper FSM depending upon the mode of the transceiver. A conditional logic block is included in the sequencer core which detects special operation codes (opcodes) for each slot to cause the microcode sequence to jump to a certain routine if a condition is met or not met.
