    摘要: Method and apparatus suited for use with a decoder receiving data serially from a network is disclosed providing synchronization throughout reception and decoding of packets of symbols. An appropriately-delayed read pointer initialization strobe used by an elastic buffer portion of the receiver provides the sequence of synchronization signals which avoids deletion of bits of packet preamble.

    摘要: In accordance with the invention, the reference portion of a primitive current switch used in emitter coupled logic or current mode logic is modified by introducing a slow device as the reference element in order to enhance the speed of turn on and turn off of the input elements. In particular, the reference transistor of a conventional ECL inverter gate or conventional CML inverter gate is replaced with a slow transistor or slow diode in order to bypass the emitter dynamic resistance. The emitter time constant of the reference element Q.sub.R is thereby increased so that the voltage on the common current source node (node 3) does not change substantially when the base of the input elements change transiently. As a consequence, the collector output of the input element, such as transistor Q.sub.A is switched on or off significantly faster.

    摘要: Methods and apparatus offload tiered memories management. The method includes obtaining a pointer to a stored memory management structure associated with tiered memories, where the memory management structure includes a plurality of memory management entries and each memory management entry of the plurality of memory management entries includes information for a memory section in one of the tiered memories. In some instances, the method includes scanning at least a part of the plurality of memory management entries. In certain instances, the method includes generating a memory profile list, where the memory profile list includes a plurality of profile entries and each profile entry of the plurality of profile entries corresponding to a scanned memory management entry in the memory management structure.

    摘要: Systems, apparatuses, and methods for implementing a multi-tiered approach to cache compression are disclosed. A cache includes a cache controller, light compressor, and heavy compressor. The decision on which compressor to use for compressing cache lines is made based on certain resource availability such as cache capacity or memory bandwidth. This allows the cache to opportunistically use complex algorithms for compression while limiting the adverse effects of high decompression latency on system performance. To address the above issue, the proposed design takes advantage of the heavy compressors for effectively reducing memory bandwidth in high bandwidth memory (HBM) interfaces as long as they do not sacrifice system performance. Accordingly, the cache combines light and heavy compressors with a decision-making unit to achieve reduced off-chip memory traffic without sacrificing system performance.
