ABSTRACT:
A digital protocol translator including a first protocol circuitry having a first I/O port adapted to communicate using a first digital protocol, the first protocol circuitry including a first controller. The translator further includes a second protocol circuitry having a second I/O port communicating using a second digital protocol different from the first digital protocol, the second protocol circuitry including a second controller in communication with the first controller, such that communications between the first I/O port and the second I/O port are translated between the first protocol and the second protocol. Preferably, the translator further includes a microprocessor and digital memory, where the microprocessor operates under the control of a program stored in the memory. Also preferably, the first controller includes a first state machine, a first plurality of registers, and a first DMA interface, and the second controller includes a second state machine, a second plurality of registers, and a second DMA interface.
