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.

摘要： We present a “directory extension” (hereinafter “DX”) to aid in prefetching between proximate levels in a cache hierarchy. The DX may maintain (1) a list of pages which contains recently ejected lines from a given level in the cache hierarchy, and (2) for each page in this list, the identity of a set of ejected lines, provided these lines are prefetchable from, for example, the next level of the cache hierarchy. Given a cache fault to a line within a page in this list, other lines from this page may then be prefetched without the substantial overhead to directory lookup which would otherwise be required.

摘要： A system for memory management including a tag controlled buffer in communication with a memory device. The memory device includes a plurality of pages divided into a plurality of individually addressable lines. The tag controlled buffer includes a prefetch buffer including at least one of the individually addressable lines from the memory device. The tag controlled buffer also includes a tag cache in communication with the prefetch buffer. The tag cache includes a plurality of tags, where each tag is associated with one of the pages in the memory device and each tag includes a pointer to at least one of the lines in the prefetch buffer. Access to the lines in the prefetch buffer is controlled by the tag cache.

摘要： A system for memory management including a tag cache in communication with one or more cache devices in a storage hierarchy is provided. The tag cache includes tags of recently accessed memory blocks, each tag corresponding to one of the memory blocks and each tag including tag contents. The tag contents include a memory block real address and one bit for every memory line in the memory block. The bits are referred to as prefetch bits. Each of the prefetch bits is reset to a non-prefetch status with a selected probability of between zero and one. 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 times or events.

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.”
摘要翻译：我们将I / O的控制功能与数据的实际缓存和传输分开。这在这里被称为“磁盘改进”。对于缓存，这样可以提高带宽和内存的利用率。为了传输数据，改善带宽并保持安全性。同样在本发明中，我们利用主机系统的未使用部分作为高速缓存。这在本文中被称为“缓存增强”。
