摘要： The present invention describes lossless data compression/decompression methods and systems. A random access memory (RAM) operates as a static dictionary and includes commonly used strings/symbols/phrases/words. An input buffer operates as a dynamic dictionary and includes input strings/phrases/symbols/words. A set-associative cache memory operates as a hash table, and includes pointers pointing to the commonly used strings/symbols/phrases/words in the static dictionary and/or pointing to one or more of the input strings/phrases/symbols/words in the dynamic dictionary. Alternatively, the set-associative cache memory combines the dynamic dictionary, the static dictionary and the hash table. When encountering a symbol/phrase/string/word in the static or dynamic dictionary in an input stream, a compressor logic or module places a pointer pointing to the symbol/phrase/string/word at a current location on the output stream. The hash table may include phrases/symbols/strings/words and/or pointers pointing to phrases/symbols/strings/words.

摘要： A computer system and a method for enhancing the cache prefetch behavior. A computer system including a processor, a main memory, a prefetch controller, a cache memory, a prefetch buffer, and a main memory, wherein each page in the main memory has associated with it a tag, which is used for controling the prefetching of a variable subset of lines from this page as well as lines from at least one other page. And, coupled to the processor is a prefetch controller, wherein the prefetch controller responds to the processor determining a fault (or miss) occurred to a line of data by fetching a corresponding line of data with the corresponding tag, with the corresponding tag to be stored in the prefetch buffer, and sending the corresponding line of data to the cache memory.

摘要： We separate the control functions of the I/O from the actual caching and transfer of data. This is referred herein as “disk improvements.” For caching, this enables improved utilization of bandwidth and memory. For transfers of data, bandwidth is improved while retaining security. Also in the present invention, we utilize unused portions of host systems to serve as a cache. This is referred herein as “cache enhancements.”

摘要： A system for memory management including a tag cache in communication with one or more cache devices in a storage hierarchy. The tag cache includes tags of recently accessed memory blocks where each tag corresponds to one of the pages and each tag includes tag contents. The tag contents control which memory lines of the corresponding memory block are prefetched into at least one of the cache devices. The tag contents are updated using a selected subset of processor references. The subset is referred to as filtered references. The tag contents are modified probabilistically at selected time or events.

摘要： A method and system for memory management are provided. The system includes a tag cache in communication with one or more cache devices in a storage hierarchy. The tag cache includes tags of recently accessed memory blocks, each tag corresponding to one of the memory blocks and including tag contents. The tag contents control which memory lines of the corresponding memory block are prefetched into at least one of the cache devices. The tag contents further include a bit to control prefetching of memory lines from a next virtual memory block, the bit referred to as a next virtual memory block bit. The next virtual memory block bit in a preceding memory block in a virtual address space is set to a prefetch status when the preceding memory block tag is in the tag cache.
