    摘要: A power line communications system including a power line for supplying ac power; a power source connected to the power line at one end; and a communications network having a plurality of devices, the devices connected to the power line at another end for (a) receiving ac power and (b) communicating information. The system also includes a security firewall coupled between the one end and the other end of the power line for securing the communications information. The security firewall passes the ac power without attenuation, but blocks the communications information from passing. The security firewall also prevents passage of interference to the communications network. In this manner a secure and interference-free communications network is established.

    摘要: In a system with hardware main memory compression, the method of this invention monitors the physical memory utilization and if physical memory is near exhaustion it forces memory to be paged out, thus freeing up real memory pages. These pages are then zeroed, thus they are highly compressible and therefore reduce the physical memory utilization. Pages that have been forced out due to high physical memory utilization are not made available for allocation. In systems where operating system changes are permitted, this invention dynamically controls the minimum size of the free page pool and zeros pages upon freeing. When the physical memory utilization falls below a critical threshold the mechanism reduces the minimum size of the free pool to allow further allocation. In systems where operating system changes are not possible, pages are allocated by a module (e.g. Device driver) and then zeroed. When the physical memory utilization falls below a critical threshold this method frees some of the explicitly set aside pages.

    摘要: A method and apparatus for reporting dynamic properties of a product using radio frequency identification device technology. With this invention, an electronic tag is equipped with a sensor which determines dynamic properties of a product when the tag is activated. The dynamic properties of the product are then either further processed into other dynamic properties. In any event either the former or the latter dynamic properties are then transmitted from the tag. Such dynamic properties could be the temperature of a product or the expiration date of the product derived from periodic measurements of the temperature of the product.

    摘要: A translation table has entries that each include a share bit and a delta bit, with pointers that point to a memory block that includes reuse bits. When two translation table entries reference identical fragments in a memory block, one of the translation table entries is changed to refer to the same memory block referenced in the other translation table entry, which frees up a memory block. The share bit is set to indicate a translation table entry is sharing its memory block with another translation table entry. In addition, a translation table entry may include a private delta in the form of a pointer that references a memory fragment in the memory block that is not shared with other translation table entries. When a translation table has a private delta, its delta bit is set.

    摘要: A method and circuit for implementing a cache directory and efficient cache tag lookup in very large cache systems, and a design structure on which the subject circuit resides are provided. A tag cache includes a fast partial large (LX) cache directory maintained separately on chip apart from a main LX cache directory (LXDIR) stored off chip in dynamic random access memory (DRAM) with large cache data (LXDATA). The tag cache stores most frequently accessed LXDIR tags. The tag cache contains predefined information enabling access to LXDATA directly on tag cache hit with matching address and data present in the LX cache. Only on tag cache misses the LXDIR is accessed to reach LXDATA.

    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: The present invention reduces the number of writes to a main memory to increase useful life of the main memory. To reduce the number of writes to the main memory, data to be written is written to a cache line in a lowest-level cache memory and in a higher-level cache memory(s). If the cache line in the lowest-level cache memory is full, the number of used cache lines in the lowest-level cache reaches a threshold, or there is a need for an empty entry in the lowest-level cache, a processor or a hardware unit compresses content of the cache line and stores the compressed content in the main memory. The present invention also provides LZB algorithm allowing decompression of data from an arbitrary location in compressed data stream with a bound on the number of characters which needs to be processed before a character or string of interest is processed.

    摘要: A fanning route generation technique is provided for multi-path networks having a shared communications fabric. The technique includes selecting a source node—destination node (S-D) group having common starting and ending sets of links from the network of interconnected nodes. Within this group, selecting the shortest routes between the S-D nodes of the group so that: selected routes substantially uniformly fan out from the source node to a center of the network and fan in from the center of the network to the destination node, thereby achieving local balance; and global balance of routes passing through links that are at a same level of the network is achieved.

    摘要: Two methods (native and clone) are used for installing software, such as an operating system, on client system(s) booting from shared storage. The native installation method configures an interconnection network to create an exclusive communication zone between the client system and the shared storage system and installs the operating system on the client system using the exclusive communication zone. After the software is installed, the method terminates the exclusive communication zone. The clone installation method utilizes a point-in-time copy feature of the shared storage system to clone an operating system drive instantaneously. After the drive is cloned, it is logically attached to a new client and the operating system is customized for that client.
