Abstract
A buffer for ordering out-of-order data includes a memory with a plurality of memory locations for temporarily storing data and a detection circuit configured for generating a control signal when the memory locations contain valid data. The detection circuit includes a first block configured for generating validity signals that identify the memory locations containing valid data and a search circuit configured for determining a search pointer as a function of the validity signals. In the case where each memory location contains valid data, the search pointer indicates the last memory location. In the case where at least one memory location is still free, the search pointer indicates the first memory location that is free.
