Speaking at a round table on cloud computing staged by the company, Lay said the technology is making the initiative possible.
Each block requires 4 computing stages to obtain a final block SAD result.
Pipelining has been applied in many area to improve system performance by overlapping executions of hardware or software computing stages.
Moreover, the proposed architecture is composed of a set of parallel computing stages connected in serial where each stage contains an hypercube of processors.
By exploiting efficiently the processing power, the execution of algorithms will be balanced between the parallel computing stages, which will improve greatly the overall performance.
To select and compare the proper block SAD results as shown in Figure 6, the signals of different block shapes and computing stages are employed to determine the appropriate mode of minimum SAD to be utilized.
Meanwhile, the signal of computing stages is also used to indicate the valid input to the SAD comparator for retrieving proper SAD results from BPU, and thus obtain the MME point with a minimum SAD for this block size.
Other 6 block sizes in H.264, that is,,,,,, and, can be organized by the combination of basic blocks, shown in Figure 7, which also describes computing stages for each variable-sized block constructed on the basic blocks to obtain VBS SAD results.
An extrapolation approach based on already computed stage values is applied to construct IMEX methods with favourable stability properties.
To construct super-convergent IMEX-Peer methods with favourable stability properties, we derive necessary and sufficient conditions on the coefficient matrices and apply an extrapolation approach based on already computed stage values.
