  • Patent number: 11157061
    Abstract: A process for processor management includes activating a delay thread running on a processor. A determination is made whether a wait event for a first thread running on the processor is in a queue. Responsive to determining that the wait event for the first thread is in the queue, a determination is made whether a wait time associated with the wait event has expired. Responsive to determining that the wait time has not expired, a determination is made if wait time exceeds a threshold. Responsive to determining that the wait time exceeds the threshold, a timer is set and a low power mode is initiated for the processor.

  • Patent number: 11036515
    Abstract: A system and corresponding method unwind instructions in an out-of-order (OoO) processor. The system comprises a mapper. In response to a restart event causing at least one instruction to be unwound, the mapper restores a present integer mapper state and present floating-point (FP) mapper state, used for mapping instructions, to a former integer mapper state and former FP mapper state, respectively. The mapper stores integer snapshots and FP snapshots of the present integer and FP mapper state, respectively, to expedite restoration to the former integer and FP mapper state, respectively. Access to the FP snapshots is blocked, intermittently, as a function of at least one FP present indicator used by the mapper to record presence of FP registers used as destinations in the instructions. Blocking the access, intermittently, improves power efficiency of the OoO processor.

    Abstract: A method of processing exceptions in an exception-driven computing-based system that operates in either initialisation mode or exception-driven mode. The method includes, upon detecting an exception has occurred, causing the processor to execute exception handling instructions. When the system is operating in initialisation mode the exception handling instructions invoke a first exception handler that causes a main register set to be saved before processing the exception and restored after processing the exception, and when the system is operating in exception-driven mode the exception handling instructions invoke a second exception handler that does not cause the main register set to be saved and restored. In some examples, the exception handling instructions are initially configured to invoke the first exception handler and are dynamically updated when the system switches from initialisation mode to exception-driven mode to invoke the second exception handler.

  • Patent number: 10635395
    Abstract: A processor (and method) includes a core that performs a floating point division through execution of various instructions. The instructions include a sign, exponent, and mantissa (SEM) separation instruction which causes the core to extract the sign, exponent and mantissa values from numerator and denominator floating point numbers. The instructions also include an unsigned mantissa division instruction which cause the core to iteratively perform a conditional subtraction operation to compute a value indicative of a mantissa of the quotient. The instructions further include a merge instruction that causes the core to generate a quotient floating point number using the extracted sign and exponent from the SEM separation instruction and the value indicative of the mantissa of the quotient.

  • Patent number: 10540200
    Abstract: A hardware context manager in a field-programmable gate array (FPGA) device includes configuration logic configured to program one or more programming regions in the FPGA device based on configuration data for implementing a target configuration of the one or more programming regions. Context management logic in the hardware context manager is coupled with the configuration logic and saves a first context corresponding to the target configuration by retrieving first state information from the set of one or more programming regions, where the first state information is generated based on the target configuration, and storing the retrieved first state information in a context memory. The context management logic restores the first context by transferring the first state information from the context memory to the one or more programming regions, and causing the configuration logic to program the one or more programming regions based on the configuration data.

  • Patent number: 10534614
    Abstract: A method of sharing a plurality of registers in a shared register pool among a plurality of microprocessor threads begins with a determination that a first instruction to be executed by a microprocessor in a first microprocessor thread requires a first logical register. Next a determination is made that a second instruction to be executed by the microprocessor in a second microprocessor thread requires a second logical register. A first physical register in the shared register pool is allocated to the first microprocessor thread for execution of the first instruction and the first logical register is mapped to the first physical register. A second physical register in the shared register pool is allocated to the second microprocessor thread for execution of the second instruction. Finally, the second logical register is mapped to the second physical register.

  • Patent number: 10474468
    Abstract: Systems, apparatuses, and methods for processing variable wavefront sizes on a processor are disclosed. In one embodiment, a processor includes at least a scheduler, cache, and multiple execution units. When operating in a first mode, the processor executes the same instruction on multiple portions of a wavefront before proceeding to the next instruction of the shader program. When operating in a second mode, the processor executes a set of instructions on a first portion of a wavefront. In the second mode, when the processor finishes executing the set of instructions on the first portion of the wavefront, the processor executes the set of instructions on a second portion of the wavefront, and so on until all portions of the wavefront have been processed. The processor determines the operating mode based on one or more conditions.

  • Patent number: 10354706
    Abstract: For an integrated circuit (IC) that is designed to execute user defined operations after initialization, a sequencing circuitry in the IC that delays the start of the user design execution until a set of initial condition has been computed and propagated is provided. The sequencing holds the first group of circuits at an initial state while a second group of circuits computes and propagates a set of initial conditions based at least partly on the initial state of the first group of circuits. The circuits in the first group when being held disregard their inputs and do not change their outputs. The first group of circuits is released from its initial state after the second group of circuits has completed computation and propagation of the set of initial conditions. The circuits in the first group when released are freed to store or clock-in new inputs and produce new outputs in order to perform the user defined operations in conjunction with the second group of circuits.
