  • Publication number: 20190179757
    Abstract: A processing system includes an interconnect fabric coupleable to a local memory and at least one compute cluster coupled to the interconnect fabric. The compute cluster includes a processor core and a cache hierarchy. The cache hierarchy has a plurality of caches and a throttle controller configured to throttle a rate of memory requests issuable by the processor core based on at least one of an access latency metric and a prefetch accuracy metric. The access latency metric represents an average access latency for memory requests for the processor core and the prefetch accuracy metric represents an accuracy of a prefetcher of a cache of the cache hierarchy.

  • Publication number: 20190179770
    Abstract: A processing system rinses, from a cache, those cache lines that share the same memory page as a cache line identified for eviction. A cache controller of the processing system identifies a cache line as scheduled for eviction. In response, the cache controller, identifies additional “dirty victim” cache lines (cache lines that have been modified at the cache and not yet written back to memory) that are associated with the same memory page, and writes each of the identified cache lines to the same memory page. By writing each of the dirty victim cache lines associated with the memory page to memory, the processing system reduces memory overhead and improves processing efficiency.

  • Patent number: 7136487
    Abstract: A system and method for automatically protecting private video content using embedded cryptographic security is disclosed. A substantially continuous video signal representing raw video content is divided into individual frames. Each frame stores a fixed amount of data in digital form. Each individual frame is encrypted into encrypted video content using an encryption cryptographic key. The encrypted frames is stored on a transportable storage medium. Encrypted frames are retrieved from the transportable storage medium. A decryption cryptographic key is verified prior to decryption. Each encrypted frame is decrypted using the decryption cryptographic key. The decrypted frames are combined into a substantially continuous video signal representing the raw video content in reconstructed form. In a further embodiment, private video content automatically authenticated using embedded cryptographic security, either alone or in conjunction with the encryption of video content.

  • Patent number: 7120252
    Abstract: A system and method for automatically protecting private video content using cryptographic security for legacy systems is disclosed. A substantially continuous video signal representing video content in the process of being recorded on a transportable storage medium is intercepted. The intercepted substantially continuous video signal is divided into individual frames. Each frame stores a fixed amount of data in digital form. Each individual frame is encrypted into encrypted video content using an encryption cryptographic key and is stored. The encrypted frames are retrieved and decrypted using a decryption cryptographic key. The decrypted frames are combined into a substantially continuous video signal and output as video content in the process of being played from the transportable storage medium. In a further embodiment, private video content automatically authenticated using embedded cryptographic security, either alone or in conjunction with the encryption of video content.

  • Patent number: 6805786
    Abstract: A relatively simple and inexpensive process for plating precious alloyed metals, such as AuSn, AuSnIn, AgSn, AuIn and AgIn. Anodes are formed from each of the metal components in the alloy and disposed in a conducting solution. The mass of each metal components is determined by Faraday's law. The target is also disposed in the conducting solution. Plating current is independently applied to each anode. The plating is conducted under an ultraviolet light sources to optimize the process. The plating alloys can be used for various purposes including attaching a semiconductor die to a substrate. Since the process does not involve exposure of the semiconductor die to a relatively high temperature for a relatively long time, the process does not pose a risk of contamination of the semiconductor by the adhesive or wax used to hold the die in place on the carrier during processing.

  • Patent number: 6198031
    Abstract: A cord or cable lock for preventing a cord or cable from being accidentally pulled out of a socket of a musical instrument, due to tugs on the cable or cord, is disclosed. The cable lock is in the form of a strip which is curled or curved at one end to give a J-shaped profile to the cable lock. Near the end distal from the curved portion, the cable lock has a hole which allows the cable lock to be mounted to a musical instrument using a screw. The curved portion of the cable lock surrounds the cable and frictionally grips the cable to keep tugs on the cable from being transmitted to a plug at the end of the cable. Thus the plug is prevented from being pulled out of the socket in the musical instrument.

  • Patent number: 5361038
    Abstract: An active load applied to the gate transmission line termination of distributed power devices reduces the low frequency noise power appearing at the output of the device. The active load, including at least one active device such as a field effect transistor, operates by transforming the input impedance of a low noise amplifier to the desired load impedance. The active load is connected to one end of an input transmission line having a plurality of impedances connected in electrical series. An input terminal is connected to the opposite end. An output transmission line, also having a plurality of impedances connected in series, has an output terminal at one end and a terminating output impedance at the other. A plurality of active devices are connected to junction points between the series connected impedances of the input and output lines.

  • Patent number: 5333922
    Abstract: A portable door secure system which consists of an elongate shank with a foot component coupled to a lower end of the shank for engaging a floor in front of a door and a yoke component coupled to an upper end of the shank for engaging an underside of a door knob on the door. The shank can be positioned at an angle between the door knob and the floor, to jam the door closed to prevent the door from being opened inwardly toward the side on which the device resides. The device disassembles into a very small compact light weight set of components so that it may easily be carried by a user typically a hotel or motel patron.

  • Patent number: 4629040
    Abstract: According to the invention, a rigid insert is provided in a soft luggage shell. The insert conforms to the configuration of the inside luggage surface and is removably held in place by a twistable retainer ring. The ring is encased in a cloth sleeve and mounted to the luggage in the vicinity of an edge of the insert. By twisting the ring, the ring and associated sleeve can be selectively placed either abuttingly against the insert or away from the insert to allow its removal. The invention also contemplates the provision of a protective shield which is removably mounted to a surface of the luggage which abuts a carrying vehicle.

    Abstract: In an intravenous fluid administration assembly, there is provided a suspended, fluid holding container having a stopper closing off its mouth, a conduit having a hollow spike inserted into the stopper for gravity flow delivery of fluid from the container to the conduit, and a clamp for preventing the unintentional separation of the spike from the stopper. The clamp has a first portion having an opening through which the container's neck extends downwardly and a second portion having an opening through which the spike extends upwardly. The first portion seats on an abutment on the container's neck and the second portion seats under a flange extending outwardly from the spike. First ends of the first and second portions are connected by a third portion of the clamp and the openings in the first and second portions extend to those portions' other free ends.
