Abstract
A system is disclosed for improving the efficiency of data transactions by permitting the length of burst transactions to be modified based upon system performance. A bus interface unit monitors the response times of memory devices, and, if WAIT periods are required before the memory device responds, the bus interface unit increases the length of the burst. Preferably, the bus interface unit includes a table of historical response times of various memory ranges, and determines an optimal burst length for each memory range. When a data transaction is made to a particular memory location, the BIU accesses the table and asserts a BURST signal for a sufficient period of time to accomplish the optimal burst length. After the optimal burst length has been reached in the existing memory transaction, the BURST signal is deasserted to end the burst cycle.
