Abstract
Apparatus and method relate to a data channel. In this apparatus, an input circuit is configured to gate a valid input with a ready output to provide a forward token ('f-token') to a first f-token register of a f-token pipeline and to a counter, and to receive data to a first data register of a data pipeline. An output circuit is configured to gate a ready input with a valid output to provide a return token ('r-token') to a first r-token register of a r-token pipeline and to a FWFT FIFO, to receive the f-token from a second f-token register of the f-token pipeline to the FWFT FIFO, and to receive the data from a second data register of the data pipeline to the FWFT FIFO. The input circuit receives the r-token from the first r-token register to a second r-token register of the r-token pipeline for the counter.
