Abstract: A backup power-source module that controls a backup power source for supplying power from a battery charged by an AC input to an electronic device when the AC input is cut off. The backup power-source module includes a selection which generates a selection signal for selecting power supplied by a battery when the electronic device is kept in an electrified state until the electronic device is shifted to a power cutoff state and there is no AC input. I.E., the selection signal causes the power supplied by the battery to be selected only when the electronic device is kept in a power cutoff state and there is no AC input.

Abstract: A wrap test for a communication interface unit used for a computer, etc. When a wrap tool 40 is connected to a SCSI device 10, a signal (TEMPWR) is output from an output device 38 to SCSI connectors 22 and 24 through a Y-type cable 14, then wrapped in the wrap tool 40 and returned to a SCSI controller 12 through resistors 28 and 30 as a signal (PSCSIWRAP) to recognize the wrap tool 40. Because the non-grounded end of a resistor 26 is connected to an input terminal of the SCSI controller 12, the resistors 28 and 30 are connected in parallel. The potential of the signal (PSCSIWRAP) is stabilized by the resistors 26, 28 and 30. If a single wrap tool is connected to the SCSI device 10, the potential of the signal (PSCSIWRAP) is stabilized by the resistors 26 and 28 or 30.

Abstract: A computing system includes a storage server having a memory organization that includes a compressed memory device for storing sectors, each sector having a sector data portion and associated header and trailers, either attached by the hosts or by components of the computing system. The compressed memory device comprises a memory directory and a plurality of fixed-size blocks.

Abstract: 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 providing compressed data integrity verification to insure detection of nearly any data corruption resulting from an anomaly anywhere in the logical processing or storage of compressed information. A cyclic redundancy code (CRC) is computed over a compressed data block as the data enters the compressor hardware, and the CRC is appended to the compressor output block before it is stored into the main memory. Subsequent read access results in comparing the CRC against a recomputation of the CRC as the block is uncompressed from the main memory. Any CRC miscompare implies an uncorrectable data error condition that may be used to interrupt the system operation.

Abstract: The present invention is directed to explaining functions with a rich graphical expression even when the number of kinds of functions required for a software increases. More particularly, a plurality of function areas 201-223 are defined in a composite icon area of the present invention. An appearance image is associated to each function area and, when a mouse pointer comes across a function area, appearance images associated to that function area are displayed as appearance images of a composite icon. A function is also associated to each function area and, when a mouse is clicked on a function area, a function which is associated to that function area is executed. The set of the function area may be changed by changing the size of a composite icon, an operation to switch the group of functions, or selection of an object to be operated upon.

Abstract: The present invention provides a method and a system for connecting together, in a VLSI chip, a plurality of macros which require data flow connections between each other. A simple standard interface is realised between all macros. Any number of macros can be connected together, also allowing concurrent transactions between 4 or more macros using a cross-bar switch. Each macro may be a master (capable of requesting connections), a slave (capable of receiving connections from a master) or both. The centralised inter-connect logic includes three major components: the cross-bar switch, which makes the connections between the macros, the address decoder, which determines which slave each master wishes to connect to and an arbiter, which arbitrates between the macros when two or more masters request a connection simultaneously.

Abstract: 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 and, wherein information stored within the main memory is indirectly accessible by a processor through an uncompressed information cache, an improved memory architecture, apparatus and method for detecting and recovering the main memory space used to store “stale” information associated with cache lines in the “modified” state, and returning the storage to an unused pool for use in storing other information. This improves the overall compression rate of the system, thus lessening the likelihood of encountering a “memory pressure” situation where the system runs low on unused memory.

Abstract: 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.
