Abstract: A memory architecture and method of partitioning a computer memory. The architecture includes a cache section, a setup table, and a compressed storage, all of which are partitioned from a computer memory. The cache section is used for storing uncompressed data and is a fast access memory for data which is frequently referenced. The compressed storage is used for storing compressed data. The setup table is used for specifying locations of compressed data stored within the compressed storage. A high speed uncompressed cache directory is coupled to the memory for determining if data is stored in the cache section or compressed storage and for locating data in the cache.

Abstract: A data processor assigns a unique identifier to each instruction. As there are a finite number of unique identifiers, the identifiers are reused during execution of a program within the data processing system. To maintain an age relationship between instructions executing in the pipeline processor, a methodology is developed to ensure that reused identifiers are properly designated as being younger than their older but larger in magnitude, counterparts. To resolve this issue, assume that the identifier assigned to each instruction has N bits, and therefore, there are 2.sup.N identifiers to be assigned to instructions in the program. The 2.sup.N identifiers are separated into 2.sup.m banks. In addition to assigning identifiers to each instruction, an identifier assignment logic circuit within the pipeline processor provides a global signal that indicates which bank is a youngest bank from which the identifiers are assigned to a remaining portion of the pipeline processor.

Abstract: An age-based arbitration scheme for enforcing data coherency in an information handling system is disclosed. As loads and stores access a cache, if a cache miss occurs, a miss request is generated and tagged with the cycle or age in which the miss is detected. If a castout is required, it is also tagged with the cycle in which the load or store access occurred, and the line being replaced or cast out is marked as being invalid in that level of hierarchy. The arbitration rules for the next level of memory hierarchy are defined such that all requests that are generated during a particular cycle are given priority over all of the requests generated during any subsequent cycle. As a result, if a load miss occurs for a cache line which is present in the castout buffer, the castout request tagged with an earlier age will be arbitrated into the next memory hierarchy level prior to the arrival of the newly generated miss requests.

Abstract: A method and system are disclosed for reducing run-time delay during conditional branch instruction execution in a pipelined processor system. A series of queued sequential instructions and conditional branch instructions are processed wherein each conditional branch instruction specifies an associated conditional branch to be taken in response to a selected outcome of processing one or more sequential instructions. Upon detection of a conditional branch instruction within the queue, a group of target instructions are fetched based upon a prediction that an associated conditional branch will be taken. Sequential instructions within the queue following the conditional branch instruction are then purged and the target instructions loaded into the queue only in response to a successful a retrieval of the target instructions, such that the sequential instructions may be processed without delay if the prediction that the conditional branch is taken proves invalid prior to retrieval of the target instructions.

Abstract: A magnetic recording disk drive with a magnetoresistive (MR) read sensor or head has a shock and vibration detection circuitry responsive to a thermoresistive signal contained in the signal from the head. The MR head is heated by an electrical bias current and is supported on the head carrier near the surface of the disk. External shock or vibration to the disk drive alters the spacing between the carrier and the disk, which causes fluctuations in the head temperature due to cooling of the heated head by the disk. These temperature fluctuations are reflected in the signal from the head as a thermoresistive signal comprising modulation of a baseline voltage level. The shock detection circuitry compares positive and negative excursions of this thermoresistive signal with a predetermined threshold voltage level. When the threshold is exceeded, indicating an external shock or vibration in excess of an allowable limit, writing of data is inhibited.

Abstract: Sensor (41) is held between its arms (63) and nubs 60 in cover (31). A circuit board (57) on which the sensor is mounted remains outside of the cover, and panels (55) of the sensor (41) extend upward to prevent the circuit board (57) from collapsing leads (45, 53) which connect the sensor to the circuit board. Reliable operation is obtained without narrow tolerances.

Abstract: An electronic package which includes a flexible substrate, stiffener and chip. The chip is bonded to the substrate, which was secured to the stiffener. Strain relief means are utilized at various locations in the package to prevent problems (e.g., tape "wrinkling") associated with relatively large differences in coefficients of thermal expansion between the package's various elements.

Abstract: This invention relates to ethoxylated acetylenic glycol compositions represented by the formula: ##STR1## wherein m and n are integers and the sum is from 4-12. These ethoxylated acetylenic diols are excellent as surfactants alone or admixed with other surfactants for use in water borne coatings.

Abstract: A hydrogen generator for hydrolyzing hydrides substantially at stoichiometry to provide hydrogen on demand to a fuel cell is disclosed. The generator comprises a sealable, pressurizable, thermally insulated vessel into which a hydride in granular form is loaded. Water, most of which may be a byproduct from the fuel cell, is controllably introduced into the vessel for reaction with the hydride to generate hydrogen. The rate of introduction of the water is determined by the demand for hydrogen at the fuel cell. Heat transfer apparatus is disposed about the vessel to control the temperature of the reaction. A stirring mechanism is disposed in the vessel to prevent clumping of the hydride, to distribute the water to unreacted hydride, and to disperse the heat of the reaction throughout the hydride mass and thence to the heat transfer apparatus. An outlet from the vessel is provided for transfer of the generated hydrogen to the fuel cell.

Abstract: This invention provides a day/night outdoor mirror for a vehicle in which the mirror is of the remote-operable type manipulated by Bowden cables at least some of which are clamped on the exterior and under compression between the clamp and the support member for the mirror so that a resilient biasing force is imposed on the support member. The device includes a pivotal mounting means for the support member, an additional Bowden cable for rotating the support member in opposition to the resilient biasing force to shift the mirror to a second angular position, and an operating element which incorporates a detent to hold the mirror in the adjusted position.
