ABSTRACT:
The present invention comprises a burst mode controller (BMC) having a slot control block, a CPU, a single-port data memory, a DMA controller and a control signal selector. When the slot control block sends a logic high enable signal to the control signal selector celecting meane within a first predetermined time slot, the BMC is enabled to transmit/receive message-type data to/from the signal port data memory. When the slot control block sends a logic low enable signal to the control signal selector within a predetermined second time slot, the DMA is enabled to access message-type data stored in the single-port data memory to a peripheral device in accordance with commands provided by the CPU.
