Abstract

A method and apparatus are provided for controlling data flow by storing variable length encoded information bits in a circular buffer in a write operation to a virtual write address comprising a first wrap bit value appended by a current write address within the buffer address range and generating an interrupt alarm if the virtual write address crosses a virtual alarm address comprising a second wrap bit value appended by an alarm address within the buffer address range, where the first and second wrap bit values each toggle between first and second values every time the current write address or alarm address, respectively, wraps around the circular buffer, thereby synchronizing data flow in the circular buffer and/or preventing buffer overflow.
