摘要： A computing system and method employing a processor device for generating real addresses associated with memory locations of a real memory system for reading and writing of data thereto, the system comprising: a plurality of memory blocks in the real memory system for storing data, a physical memory storage for storing the pages of data comprising one or more real memory blocks, each real memory block partitioned into one or more sectors, each comprising contiguous bytes of physical memory; a translation table structure in the physical memory storage having entries for associating a real address with sectors of the physical memory, each translation table entry including one or more pointers for pointing to a corresponding sector in its associated real memory block, the table accessed for storing data in one or more allocated sectors for memory read and write operations initiated by the processor; and, a control device for directly manipulating entries in the translation table structure for performing page operations without actually accessing physical memory data contents. In this system, the actual data of the pages involved in the operation are never accessed by the processor and therefore is never required in the memory cache hierarchy, thus eliminating the cache damage normally associated with these block operations. Further the manipulation of the translation table will involve reading and writing a few bytes to perform the operation as opposed to reading and writing the hundreds or thousands of bytes in the pages being manipulated.

摘要翻译：一种计算系统和方法，所述计算系统和方法采用处理器设备来生成与实际存储器系统的存储器位置相关联的用于读取和写入数据的实际地址，所述系统包括：所述实际存储器系统中的用于存储数据的多个存储块，用于存储包括一个或多个实际存储器块的数据页面的存储器存储器，每个实际存储器块被划分成一个或多个扇区，每个扇区包括物理存储器的连续字节; 物理存储器存储器中的转换表结构具有用于将实际地址与物理存储器的扇区相关联的条目，每个转换表条目包括用于指向其相关联的实际存储器块中的对应扇区的一个或多个指针，用于由处理器发起的用于存储器读和写操作的一个或多个分配扇区中的数据; 以及用于直接操纵翻译表结构中的条目以执行页面操作而不实际访问物理存储器数据内容的控制装置。在该系统中，操作所涉及的页面的实际数据从不被处理器访问，因此在存储器高速缓存层次结构中从不需要这样的数据，从而消除通常与这些块操作相关联的高速缓存损坏。此外，翻译表的操作将涉及读取和写入几个字节以执行操作，而不是在被操纵的页面中读取和写入数百或数千字节。

摘要： In a processing system having a main memory wherein information is stored in a compressed format for the purpose of gaining additional storage through compression efficiencies, a method and apparatus for enabling termination of a pending compression operation for the purpose of writing the data directly to the main memory, bypassing the compressor hardware during stall conditions. Memory space (compressibility) is sacrificed for higher system performance during these temporary write back stall events. A background memory scrub later detects and recovers the “lost” compressibility by recycling the uncompressed data back through the compressor during idle periods.

摘要： A method and system for prefetching in computer system are provided. The method in one aspect includes using a prefetch engine to perform prefetch instructions and to translate unmapped data. Misses to address translations during the prefetch are handled and resolved. The method also includes storing the resolved translations in a respective cache translation table. A system for prefetching in one aspect includes a prefetch engine operable to receive instructions to prefetch data from the main memory. The prefetch engine is also operable to search cache address translation for prefetch data and perform address mapping translation, if the prefetch data is unmapped. The prefetch engine is further operable to prefetch the data and store the address mapping in one or more cache memory, if the data is unmapped.

摘要： In response to receipt of an input string, an attempt is made to identify, in a template store, a closely matching template for use as a compression template. In response to identification of a closely matching template that can be used as a compression template, the input string is compressed into a compressed string by reference to a longest common subsequence compression template. Compressing the input string includes encoding, in a compressed string, an identifier of the compression template, encoding substrings of the input string not having commonality with the compression template of at least a predetermined length as literals, and encoding substrings of the input string having commonality with the compression template of at least the predetermined length as a jump distance without reference to a base location in the compression template. The compressed string is then output.

摘要： A computer system having a combined memory. A first logical partition of the combined memory is a main memory region in a storage memory. A second logical partition of the combined memory is a direct memory region in a main memory. A memory controller comprising a storage controller is configured to receive a memory access request including a real address from a processor, determine whether the real address is for the first logical partition or for the second logical partition. If the address is for the first logical partition the storage controller communicates with an IO controller in the storage memory to service the memory access request. If the address is for the direct memory region, the memory controller services the memory access request in a conventional manner.

摘要： A memory system and methods for memory manage are presented. The memory system includes a volatile memory electrically connected to a high-density memory; a memory controller that expects data to be written or read to or from the memory system at a bandwidth and a latency associated with the volatile memory; a directory within the volatile memory that associates a volatile memory address with data stored in the high-density memory; and redundant storage in the high-density memory that stores a copy of the association between the volatile memory address and the data stored in the high-density memory. The methods for memory management allow writing to and reading from the memory system using a first memory read/write interface (e.g. DRAM interface, etc.), though data is stored in a device of a different memory type (e.g. FLASH, etc.).
