  • Patent number: 10365926
    Abstract: A programmable processor and method for improving the performance of processors by expanding at least two source operands, or a source and a result operand, to a width greater than the width of either the general purpose register or the data path width. The present invention provides operands which are substantially larger than the data path with of the processor by using the contents of a general purpose register to specify a memory address at which a plurality of data path widths of data can be read or written, as well as the size and shape of the operand. In addition, several instructions and apparatus for implementing these instructions are described which obtain performance advantages if the operands are not limited to the width and accessible number of general purpose registers.

  • Patent number: 10108467
    Abstract: A data processing system includes an instruction pipeline, a bus interface unit, and a cache. The instruction pipeline is configured to assert a discard signal when a speculative read request is determined to have been mispredicted. The speculative read request has a corresponding access address. The bus interface unit is configured to communicate with an external system interconnect. The cache includes a cache array and cache control circuitry. The cache control circuitry is configured to receive the discard signal from the instruction pipeline and, when the discard signal is asserted after the access address has been provided to the external system interconnect by the bus interface unit in response to a determination by the cache control circuitry that the access address missed in the cache array, selectively store the read information returned from the access address into the cache array.

  • Patent number: 10097219
    Abstract: A waveform generator circuit provides low spurious output signal and includes a primary DDS for generating a RF signal at a first frequency. A DAC receives an output signal from the primary DDS and converts the digital DDS output to an analog output. A spectrum analyzer identifies spurious signals in the DAC output determining the amplitude and frequency characteristics of the spurious signals. The waveform generator includes at least one cancellation DDS configured to generate a pre-distortion signal corresponding to frequencies where spurious signals are expected due to non-linearities in the DAC circuitry. The pre-distortion signals are phase offset from the determined spurious signals to cancel the spurious signals. The pre-distortion signals are combined with the output of the primary DDS. The combined signal contains the primary DDS output signal and pre-distortion signals to produce an analog output signal which cancels out the expected spurious signals.

  • Patent number: 9990324
    Abstract: Embodiments of the present invention are directed to a configuration interface of a network ASIC. The configuration interface allows for two modes of traversal of nodes. The nodes form one or more chains. Each chain is in a ring or a list topology. A master receives external access transactions. Once received by the master, an external access transaction traverses the chains to reach a target node. A target node either is an access to a memory space or is a module. A chain can include at least one decoder. A decoder includes logic that determines which of its leaves to send an external access transaction to. In contrast, if a module is not the target node, then the module passes an external access transaction to the next node coupled thereto; otherwise, if the module is the target node, the transmission of the external access transaction stops at the module.

  • Patent number: 9946543
    Abstract: A processor includes an execution pipeline configured to execute instructions for threads, wherein the architectural state of a thread includes a set of register windows for the thread. The processor also includes a physical register file (PRF) containing both speculative and architectural versions of registers for each thread. When an instruction that writes to a destination register enters a rename stage, the rename stage allocates an entry for the destination register in the PRF. When an instruction that has written to a speculative version of a destination register enters a commit stage, the commit stage converts the speculative version into an architectural version. It also deallocates an entry for a previous version of the destination register from the PRF. When a register-window-restore instruction that deallocates a register window enters the commit stage, the commit stage deallocates local and output registers for the deallocated register window from the PRF.
