Abstract: A computing system is provided which includes a processor having a cache memory. The cache memory includes a plurality of independently configurable subdivisions, each subdivision including a memory array. A service element (SE) of the computing system is operable to cause a built-in-self-test (BIST) to be executed to test the cache memory, the BIST being operable to determine whether any of the subdivisions is defective. When it is determined that one of the subdivisions of the cache memory determined defective by the BIST is non-repairable, the SE logically deletes the defective subdivision from the system configuration, and the SE is operable to permit the processor to operate without the logically deleted subdivision. The SE is further operable to determine that the processor is defective when a number of the defective subdivisions exceeds a threshold.

Abstract: An apparatus and method for protecting a computer system from array reliability failures uses Array Built-In Self-Test logic along with code and hardware to delete cache lines or sets that are defective, identify corresponding fuse repair values, proactively call home if spare fuses are not available, schedule soft fuse repairs for the next system restart, schedule line deletes at the next restart, store delete and fuse repairs in a table (tagged with electronic serial id, timestamp of delete or ABIST fail event, address, and type of failure) and proactively call home if there were any missed deletes that were not logged. Fuse information can also be more permanently stored into hardware electronic fuses and/or EPROMs. During a restart, previous repairs are able to be applied to the machine so that ABIST will run successfully and previous deletes to be maintained with checking to allow some ABIST failures which are protected by the line deletes to pass.

Abstract: An apparatus for objectively detecting ocular disorders adapted to the expedient examination of uncooperative patients generally comprises structures for collimating light into two predetermined paths for coaxial illumination of a person's right and left eye; structures for conditioning the collimated light; apertures for illuminating and retroflecting the collimated light by a person's eyes; and structures for detecting the relative intensities of the retroflected collimated light. A method for expediently examining uncooperative patients adapted to objectively detecting an ocular disorder comprises coaxially illuminating each eye; effecting a relative position between the apertures of an apparatus and a patient'eyes so that brief illuminating contact with the collimated light is effected; retroflecting the collimating light illuminating each eye; and measuring the relative intensities of the retroflected collimated light so that ocular disorders can be objectively determined.
