Abstract
A first request is received from a window checker, requesting to read cell data from a window buffer or write cell data into the window buffer, where the first request contains at least first cell index. A second request is received from a window releaser, requesting to read cell data from the window buffer or write cell data into the window buffer, where the second request contains at least second cell index. A register stores the first cell index, the second cell index, a first lock flag indicating whether the window checker has read cell data but hasn't written cell data back and a second lock flag indicating whether the window releaser has read cell data but hasn't written cell data back. One of the requests is granted according to the first and second cell indices and the first and second lock flags.
