    Abstract: A first register has a lane storing first input data and a second register has a lane storing second input data elements. A width of the lane of the second register is equal to a width of the lane of the first register. A single-instruction-multiple-data (SIMD) lane has a lane width equal to the width of the lane of the first register. The SIMD lane is configured to perform a sliding window operation on the first input data elements in the lane of the first register and the second input data elements in the lane of the second register. Performing the sliding window operation includes determining a result based on a first input data element stored in a first position of the first register and a second input data element stored in a second position of the second register. The second position is different from the first position.

    Abstract: An electronic data processing device comprises: a processor (1); a serial interface comprising a connection for incoming data (16) and a connection for outgoing data (18); a hardware serial-interface controller (6) for controlling the serial interface; and a reception buffer (22) for receiving incoming data. The processor is arranged automatically to read data written to the reception buffer. The device is arranged so that the processor can indicate to the serial interface controller that it is unable to accept data. The controller is arranged to respond to incoming data by sending a rejection message from the outgoing serial connection and to prevent incoming data from being placed in the reception buffer.

    Abstract: In one embodiment, a processor includes 32-bit and 64-bit machine level instructions to compute a 4D Z-curve Index. A processor decode unit is configured to decode a z-curve ordering instruction having three source operands, each operand associated with one of a first, second, or third coordinate and a processor execution unit is configured to execute the decoded instruction before outputting the 4D Z-curve index to a location specified by a destination operand.

    Abstract: A method and apparatus for executing floating point and packed data instructions using a single physical register file that is aliased. According to one aspect of the invention, processor is provided that includes a decode unit, a mapping unit, and a storage unit. The decode unit is configured to decode instructions and their operands from at least one instruction set including at least a first and second set of instructions. The storage unit includes a physical register file. The mapping unit is configured to operands used by the first set of instructions to the physical register file in a stock referenced manner. In addition, the mapping unit is configured to map operands used by the second set of instructions to the same physical register file in a non-stack reference manner.

    Abstract: A data processing system 2 includes a stack pointer register 26, 28, 30, 32 storing a stack pointer value for use in stack access operations to a stack data store 44, 46, 48, 50. Stack alignment checking circuitry 36 which is selectively disabled may be provided to check memory address alignment of the stack pointer value associated with a stack memory access. The action of the stack alignment checking circuitry 36 is independent of any further other alignment checking performed in respect of all memory accesses. Thus, general alignment checking circuitry 38 may be provided and independently selectively disabled in respect of any memory access.
