    摘要： Instruction execution includes fetching an instruction that comprises a first set of one or more bits identifying the instruction, and a second set of one or more bits associated with a first address value. It further includes executing the instruction to determine whether to perform a trap, wherein executing the instruction includes selecting from a plurality of tests at least one test for determining whether to perform a trap and carrying out the at least one test. The second set of one or more bits is used in the determination of whether to perform the trap; and the plurality of tests includes a matrix test that determines whether a data value being stored as pointed to by the first address value is escaping from one of a plurality of managed memory types to another one of the plurality of managed memory types and generates a trap in the event that the data value is determined to be escaping from one of the plurality of managed memory types to another one of the plurality of managed memory types, wherein the matrix test is based on a matrix associated with garbage collection and a matrix entry located using at least some of the first set of one or more bits and at least some of the second set of one or more bits.

    摘要： A method and an apparatus for data processing between multiple execution units using local and global register bypasses is disclosed. In one embodiment, the device contains a register file, at least two bypass circuits, a plurality of execution units, and a control circuit. Each bypass circuit connects to at least one execution unit. The control circuit, which is coupled to the execution units, limits no more than one clock delay per each execution clock cycle. The control circuit further designates delay clock cycles for handling delays.

    摘要： A method and an apparatus for implementing mixed scalar and vector values in a digital processing system. In one embodiment, a digital processing system, which contains processing unit and memories, is capable of identifying a first data in a first scalar register and a second data in a vector register. Upon fetching the first data as a first operand and the second data as a second operand, the processing unit performs an operation between the first and second operands in response to an operator. After operations, the result is subsequently stored in a second scalar register.

    摘要： A technique for performing a plurality of operations in a shared memory system having a plurality of addresses is disclosed. The technique includes entering into a speculative mode, speculatively performing each of the plurality of operations on addresses in the shared memory system, marking addresses in the shared memory system that have been operated on speculatively as being in a speculative state, and exiting the speculative mode, wherein exiting the speculative mode includes marking the addresses in the shared memory system that have been operated on as being in a non-speculative state.

    摘要： A method and a device including, in one embodiment, a multiply array and at least one adder to perform a floating-point multiplication followed by an addition when operands are in floating-point format. The device is also configured to perform an integer multiplication followed by an accumulation when operands are in integer format. The device is further configured to perform a floating-point multiply-add or an integer multiply-accumulation in response to control signals. In another embodiment, the device contains an adder and the adder is capable of performing a floating-point addition and an integer accumulation. The adder is configured to be extra wide to reduce operand misalignment. Moreover, the device stalls the process in response to operand misalignment.

    摘要： Accessing memory in an array includes performing a first instruction, including by determining whether an index used by the first instruction is within a valid range and in the event that the index is within a valid range, determining a memory address related to an array element that corresponds to the index. Accessing memory in the array further includes, in the event that the index is within a valid range, performing a second instruction to access the array element, the access being based at least in part on the memory address determined by the first instruction.
