Abstract
A write buffer unit operates in a cached memory microprocessor system by dynamically reconfigurable timed flushing of a queue of coalescing write buffers in the unit. Each time an additional one of the coalescing write buffers is allocated, a time-out period is generated which is inversely related to the number of allocated write buffers. After one of the allocated write buffers times out by exceeding the time-out period with no write activity to the coalescing write buffer, a controller in the unit determines the least recently written to allocated write buffer, and generates control signals to flush that write buffer.
