Mirrored memory used to assist communication between processors in RAID devices

摘要

A method and apparatus performs hardware assisted communication between processors. In response to direction from a first processor (304), a first coprocessor (306) writes information in a first block of mirrored memory (310). Mirrored memory is maintained, allowing a second coprocessor to read the information from a second block of mirrored memory. The information is saved in memory accessible to a second processor. The information is accessed by the second processor.
