<p>The present invention provides a caching technique for improving system performance in RAID (Redundant Arrays of Inexpensive Disks) applications. The memory caching architecture technique according to the present invention creates a substantial improvement on the system host bus (100), especially for a RAID application system, implementing an Exclusive-OR (XOR) function in hardware. By pulling the XOR operation from software and by implementing the XOR function in hardware (150) and by removing the unnecessary data transfer from the XOR operation, a significant improvement on the host bus bandwith can be achieved.</p> |
