Abstract:
A method and apparatus for adaptive buffer sizing adjusts the size of the buffer at different levels using a “high water mark” to different levels for different system conditions. The high water mark is used by the buffer logic as an indication of when to assert the buffer “Full” flag. In turn, the full flag is used by the instruction fetch logic as an indication of when to stop fetching further instructions.
