Input/output pin allocation for data streams of variable widths

摘要

There is described a method and system for inputting/outputting multiple data streams of variable widths. Input/output pins are grouped together via a plurality of transfer blocks, each transfer block being controlled by an independent clock. Data streams can therefore be input/output using asynchronous clocks. Two data streams can also be input/output on a single pin using the rising and falling edge of the clock.
