摘要： Error correction circuitry attempts to detect and correct on the fly erroneous words within random access memory (RAM) within a computer system. RAM errors are scrubbed or corrected back in the memory without delaying the memory access cycle. Rather, the address of the section or row of RAM that contains the correctable error is latched for later used by an interrupt-driven firmware memory-error scrub routine. This routine reads and rewrites each word within the indicated memory section--the erroneous word is read, corrected on-the-fly as it is read, and then rewritten back into memory correctly. If the size of the memory section exceeds a predetermined threshold, then the process of reading and re-writing that section is divided into smaller sub-processes that are distributed in time using a delayed interrupt mechanism. Duration of each memory scrubbing subprocess is kept short enough that the response time of the computer system is not impaired with the housekeeping task of scrubbing RAM memory errors. System management interrupts and firmware may be used to implement the memory-error scrub routine, which makes it independent of and transparent to the various operating systems that may be run on the computer system.

摘要： A method and system for dynamically sizing a dedicated memory in a shared memory buffer architecture. At initial boot, system BIOS programs control register to allocate a dedicated memory of a desired size. The size of the dedicated memory allocated is dependent on the performance requirements. If after initial boot, the performance requirements change, it may necessitate a change in dedicated memory size. By reprogramming the control registers, the dedicated memory size is dynamically changed without any manual manipulation of internal components.

摘要： A method and system for allowing an arbitrary operating boot in a shared memory buffer architecture system. A chipset including a memory controller, a bridge, and an arbitration unit is used to control access to a shared physical memory. The physical memory is divided between the system memory and dedicated memory to be used by one or more devices. A portion of the physical memory is allocated as a dedicated memory for some system device. The remainder of the memory may be allocated as system memory. The allocation is performed by a system BIOS either at initial start up or through system BIOS calls made during initialization of the device to use the dedicated memory. Programmable bits in the chipset are programmed to prevent the memory controller from claiming dedicated memory accesses during the boot of an operating system. Since the operating system's attempts to write to the dedicated memory are not claimed by the memory controller during memory sizing, they are forwarded to an I/O bus. No 1/0 device claims these addresses, so a memory sizing read back is unanswered, and the operating system is caused to believe the top of memory has been reached below the dedicated memory. If the O/S does not do memory sizing, the system BIOS provides the O/S with the size of system memory available. Thus, in either case, the dedicated memory allocation is transparent to the O/S, and an arbitrary O/S may be employed with the system.
