摘要： A method and system for allowing a processor or I/O master to address more system memory than physically exists are described. A Compressed Memory Management Unit (CMMU) may keep least recently used pages compressed, and most recently and/or frequently used pages uncompressed in physical memory. The CMMU translates system addresses into physical addresses, and may manage the compression and/or decompression of data at the physical addresses as required. The CMMU may provide data to be compressed or decompressed to a compression/decompression engine. In some embodiments, the data to be compressed or decompressed may be provided to a plurality of compression/decompression engines that may be configured to operate in parallel. The CMMU may pass the resulting physical address to the system memory controller to access the physical memory. A CMMU may be integrated in a processor, a system memory controller or elsewhere within the system.

摘要： A method and system for identifying and configuring device-enhanced memory modules at system startup is described. A driver is described that performs a wakeup procedure at startup to identify installed device-enhanced memory modules, detect memory implementations such as interleaving and striping on memory modules, detect error detection and correction (ECC) implementations, and to configure the identified device-enhanced memory modules to use the detected implementations. The method may include several phases including, but not limited to, a start block phase, an ECC configuration phase, an ECC check phase, an interleave detect and configuration phase, a buffer check phase, and a final configuration phase. One or more of the phases may be performed at system startup and/or during normal system operation. Methods for shutting down and providing a sleep mode for device-enhanced memory modules are also described.

摘要： An memory module including parallel data compression and decompression engines for improved performance. The memory module includes MemoryF/X Technology. To improve latency and reduce performance degradations normally associated with compression and decompression techniques, the MemoryF/X Technology encompasses multiple novel techniques such as: 1) parallel lossless compression/decompression; 2) selectable compression modes such as lossless, lossy or no compression; 3) priority compression mode; 4) data cache techniques; 5) variable compression block sizes; 6) compression reordering; and 7) unique address translation, attribute, and address caches. The parallel compression and decompression algorithm allows high-speed parallel compression and high-speed parallel decompression operation. The memory module-integrated data compression and decompression capabilities remove system bottlenecks and increase performance. This allows lower cost systems due to smaller data storage, reduced bandwidth requirements, reduced power and noise.

摘要： An ASIC device embedded into the memory subsystem of a computing device used to accelerate the transfer of active memory pages for usage by the system CPU from either compressed memory cache buffer or the addition of a compressed disk subsystem for improved system cost and performance. The Compression Enhanced Dual In-line Memory Module of the present invention uses parallel lossless compression and decompression engines embedded into the ASIC device for improved system memory page density and I/O subsystem data bandwidth. In addition, the operating system software optimizes page transfers between compressed disk partitions, compressed cache memory and inactive/active page memory within the computer system. The disclosure also indicates preferred methods for initialization, recognition and operation of the ASIC device transparently within industry standard memory interfaces and subsystems. The system can interface to present operating system software and applications, which enable optimal usage for the compressed paging system memory environment. The integrated parallel data compression and decompression capabilities of the compactor ASIC mounted on industry standard memory modules, along with the software drivers and filters of the present invention keep recently used pages compressed in the system memory. Additional performance is gained by the transfer of compressed pages between the system memory and the disk and network subsystems. In addition, the present invention may reduce the amount of data transferred between distributed computers across the LAN or WAN by the transmission of compressed page data between remote systems or distributed databases.

摘要： An integrated memory controller (IMC) including MemoryF/X Technology which includes data compression and decompression engines for improved performance. The memory controller (IMC) of the present invention preferably selectively uses a combination of lossless, lossy, and no compression modes. Data transfers to and from the integrated memory controller of the present invention can thus be in a plurality of formats, these being compressed or normal (non-compressed), compressed lossy or lossless, or compressed with a combination of lossy and lossless. The invention also indicates preferred methods for specific compression and decompression of particular data formats such as digital video, 3D textures and image data using a combination of novel lossy and lossless compression algorithms in block or span addressable formats. To improve latency and reduce performance degradations normally associated with compression and decompression techniques, the MemoryF/X Technology encompasses multiple novel techniques such as: 1) parallel lossless compression/decompression; 2) selectable compression modes such as lossless, lossy or no compression; 3) priority compression mode; 4) data cache techniques; 5) variable compression block sizes; 6) compression reordering; and 7) unique address translation, attribute, and address caches. The parallel compression and decompression algorithm allows high-speed parallel compression and high speed parallel decompression operation. The IMC also preferably uses a special memory allocation and directory technique for reduction of table size and low latency operation. The integrated data compression and decompression capabilities of the IMC remove system bottle-necks and increase performance. This allows lower cost systems due to smaller data storage, reduced bandwidth requirements, reduced power and noise.

摘要： A system and method for performing parallel data compression which processes stream data at more than a single byte or symbol (character) at one time. The parallel compression engine modifies a single stream dictionary based (or history table based) data compression method, such as that described by Lempel and Ziv, to provide a scalable, high bandwidth compression. The parallel compression method examines a plurality of symbols in parallel, thus providing greatly increased compression performance. The method first involves receiving uncompressed data, wherein the uncompressed data comprises a plurality of symbols. The method maintains a history table comprising entries, wherein each entry comprises at least one symbol. The method operates to compare a plurality of symbols with entries in the history table in a parallel fashion, wherein this comparison produces compare results. The method then determines match information for each of the plurality of symbols based on the compare results. The step of determining match information involves determining zero or more matches of the plurality of symbols with each entry in the history table. The method then outputs compressed data in response to the match information.
