  • Suspend and resume in a time shared coprocessor
    Patent number: 9852095
    Abstract: Multiple clients may attempt to utilize a coprocessor engine within a coprocessor simultaneously. However, each engine may accomplish the particular function for which it is designed for one client at a time. Therefore, to transition from performing coprocessor engine operations between clients, the coprocessor engine may be suspended from performing operations for a first client so that it may begin performing operations for a second client. Prior to such transition, the coprocessor engine saves metadata about its operation state at the time of the suspend. At a subsequent time, when operations for the first client are to resume, the operating state of the coprocessor engine is determined utilizing the metadata and operations for the first client resume.

  • Hybrid compression for large history compressors
    Patent number: 9836238
    Abstract: A compression engine and method for optimizing the high compression of a content addressable memory (CAM) and the efficiency of a static random access memory (SRAM) by synchronizing a CAM with a relatively small near history buffer and an SRAM with a larger far history buffer. An input stream is processed in parallel through the near history and far history components and an encoder selects for the compressed output the longest matching strings from matching strings provided by each of the near history and far history components.

  • HYBRID COMPRESSION FOR LARGE HISTORY COMPRESSORS
    Publication number: 20170192709
    Abstract: A compression engine and method for optimizing the high compression of a content addressable memory (CAM) and the efficiency of a static random access memory (SRAM) by synchronizing a CAM with a relatively small near history buffer and an SRAM with a larger far history buffer. An input stream is processed in parallel through the near history and far history components and an encoder selects for the compressed output the longest matching strings from matching strings provided by each of the near history and far history components. A further optimization is enabled by selectively disabling one or the other of the two types of compressors.

  • METHOD TO REDUCE REACTIVATION TIME OF CLOUD BASED SERVICES
    Publication number: 20170134518
    Abstract: A method for reducing reactivation time of services that includes examining page faults that occur during processing of a service after the service has been inactive to provide a plurality of prefetch groups, and formulating a prefetch decision tree from page fault data in the prefetch groups. Pages from an initial page table for the service following a reactivated service request are then compared with the prefetched pages in the resident memory in accordance with the prefetch decision tree. Pages in the page table that are not included in said prefetched pages are paged in. A process to provide to provide the service is executed using the page table. Executing the process substantially avoids page faults.

  • Concurrent error detection in a ternary content-addressable memory (TCAM) device
    Patent number: 9606861
    Abstract: A plurality of data words are written into a TCAM; each has binary digits and don't-care digits. Contemporaneously, for each of the words: a first checksum is calculated on the binary digits; and the following are stored in a corresponding portion of a RAM: an identifier of the binary digits and the first checksum. The ternary content-addressable memory is queried with an input word. Upon the querying yielding a match, further steps include retrieving, from the random-access memory, corresponding values of the identifier of the binary digits and the first checksum; computing a second checksum on the input word, using the identifier of the binary digits; and if the second and first checksums are not equal, determining in real time that the match is a false positive.
