ABSTRACT:
A high performance digital signal processor includes a bidirectional communication port for communication with an external device. The bidirectional communication port includes a first transmitting circuit for transmitting to the external device a first clock on a first control line in a transmit mode and for transmitting data words on plural data lines in synchronism with the first clock, and a first receiving circuit for receiving a first acknowledge signal on a second control line in the transmit mode. The communication port further includes a second receiving circuit for receiving a second clock on the second control line in a receive mode and for receiving data words on the data lines in synchronism with the second clock, and a second transmitting circuit for transmitting a second acknowledge signal on the first control line in the receive mode. The communication port further includes switching means for switching between the transmit mode and the receive mode.
