Claim One:
1. An apparatus for translating a data frame by including or removing a field in said data frame while transferring said data frame from a first data bus to a second data bus, comprising: a register array having: an input coupled to said first data bus for receiving said data frame, means for holding said field, and an output for transmitting said data frame; a selector having: a first data input coupled to said first data bus for receiving said data frame, a second data input coupled to said output of said register array for receiving said data frame, a data output coupled to said second data bus for transmitting said data frame, and a selector input for receiving a first signal to select said first data input and a second signal to select said second data input; and, decoder having: an input coupled to said first data bus for receiving said data frame, an output coupled to said selector input of said selector for transmitting, while said register array is holding said field, said first signal to select said first data input thereby removing from said data frame said field, or said second signal to select said second data input thereby including in said data frame said field, means for decoding said data frame to determine when said output will transmit said first signal or said second signal.
