20150100764 | DYNAMICALLY DETECTING UNIFORMITY AND ELIMINATING REDUNDANT COMPUTATIONS TO REDUCE POWER CONSUMPTION - One embodiment of the present invention includes techniques to decrease power consumption by reducing the number of redundant operations performed. In operation, a streamlining multiprocessor (SM) identifies uniform groups of threads that, when executed, apply the same deterministic operation to uniform sets of input operands. Within each uniform group of threads, the SM designates one thread as the anchor thread. The SM disables execution units assigned to all of the threads except the anchor thread. The anchor execution unit, assigned to the anchor thread, executes the operation on the uniform set of input operands. Subsequently, the SM sets the outputs of the non-anchor threads included in the uniform group of threads to equal the value of the anchor execution unit output. Advantageously, by exploiting the uniformity of data to reduce the number of execution units that execute, the SM dramatically reduces the power consumption compared to conventional SMs. | 04-09-2015 |

20150254066 | DATA PROCESSING APPARATUS AND METHOD FOR MULTIPLYING FLOATING POINT OPERANDS - A data processing apparatus and method are provided for multiplying first and second normalised floating point operands in order to generate a result, each normalised floating point operand comprising a significand and an exponent. Exponent determination circuitry is used to compute a result exponent for a normalised version of the result, and rounding value generation circuitry then generates a rounding value by shifting a rounding constant in a first direction by a shift amount that is dependent on the result exponent. Partial product generation circuitry multiplies the significands of the first and second normalised floating point operands to generate the first and second partial products, and the first and second partial products are then added together, along with the rounding value, in order to generate a normalised result significand. Thereafter, the normalised result significand is shifted in a second direction opposite to the first direction, by the shift amount, in order to generate a rounded result significand. This provides a particularly efficient mechanism for multiplying floating point numbers, whilst correctly rounding the result in situations where the result is subnormal. | 09-10-2015 |
20150261498 | DATA PROCESSING APPARATUS AND METHOD FOR PERFORMING A SHIFT FUNCTION ON A BINARY NUMBER - A data processing apparatus and method are provided for performing a shift function on a binary number. The apparatus comprises count determination circuitry for determining a number of contiguous bit positions in the binary number that have a predetermined bit value, the count determination circuitry outputting a count value indicative of the number of contiguous bit positions determined. In parallel with the operation of the count determination circuitry, coarse shifting circuitry is used to determine, for at least one predetermined number of contiguous bit positions, whether that predetermined number of contiguous bit positions within the binary number has said predetermined bit value. An initial shift operation is then performed on the binary number based on that determination in order to produce an intermediate binary number. Once the count value is available from the count determination circuitry, fine shifting circuitry then performs a further shift operation on the intermediate binary number, based on the count value output by the count determination circuitry, in order to produce the result binary number. This provides an efficient mechanism for performing a shift function on a binary number, whilst still capturing the count value from the count determination circuitry. | 09-17-2015 |

Comparison circuitry compares the bit location indicator with the input data value and indicates a saturation condition if any bits are indicated by the bit position indicator for bit locations which hold set bits in the input data value. A faster indication of the saturation condition thus results. | 09-24-2015 |
