| 20110320768 | METHOD OF, AND APPARATUS FOR, MITIGATING MEMORY BANDWIDTH LIMITATIONS WHEN PERFORMING NUMERICAL CALCULATIONS - There is provided a method of, and apparatus for, processing a computation on a computing device comprising at least one processor and a memory, the method comprising: storing, in said memory, plural copies of a set of data, each copy of said set of data having a different compression ratio and/or compression scheme; selecting a copy of said set of data; and performing, on a processor, a computation using said selected copy of said set of data. By providing such a method, different compression ratios and/or compression schemes can be selected as appropriate. For example, if high precision is required in a computation, a copy of the set of data can be chosen which has a low compression ratio at the expense of processing time and memory transfer time. In the alternative, if low precision is acceptable, then the speed benefits of a high compression ratio and/or lossy compression scheme may be utilised. | 12-29-2011 |
| 20110302231 | METHOD AND APPARATUS FOR PERFORMING NUMERICAL CALCULATIONS - There is provided a method of processing an iterative computation on a computing device comprising at least one processor. Embodiments of the method comprises performing, on a processor, an iterative calculation on data in a fixed point numerical format having a scaling factor, wherein the scaling factor is selectively variable for different steps of said calculation in order to prevent overflow and to minimise underflow. By providing such a method, the reliability, precision and flexibility of floating point operations can be achieved whilst using fixed point processing logic. The errors which fixed-point units are usually prone to generate if the range limits are exceeded can be mitigated, whilst still providing the advantage of a significantly reduced logic area to perform the calculations in fixed point. | 12-08-2011 |
| 20110145447 | METHOD OF TRANSFERRING DATA, A METHOD OF PROCESSING DATA, AN ACCELERATOR, A COMPUTER SYSTEM AND A COMPUTER PROGRAM - The invention provides a method of transferring data from a data array within a main memory of a computer to an accelerator for processing, the embodiment of the method comprising: at the accelerator, requesting data from the main memory and generating a data stream between the main memory and the accelerator, the generated data stream including data from the data array; and, using an offset to determine the scheduling of array elements within the generated data stream. | 06-16-2011 |
