The paper presents the design of an Automatic Target Recognition (ATR) algorithm on the IBM Cell Broadband Engine (Cell BE). The implementation utilizes several optimizations that exploit both the specific algorithm constructs of the ATR and the architectural features of the Cell processor. We discuss a total of 8 optimizations and present performance improvements achieved by their application. The latency of the Cell BE implementation of the ATR algorithm is 0.070 seconds on the Sony PlayStation3 (PS3) platform. The achieved performance is more than 25 times faster than the fully optimized PowerPC implementation and almost 20 times faster than our best efforts on a Pentium4 CPU.

Despite the many advantages in digital TV, users get into difficulties when they navigate channels to find their preferred program. Multiple PIP or mosaic style display which displays multiple channels in a screen simultaneously can be considered as good way to help easy channel navigation. In this paper, we propose a method that can display multiple channels with limited number of tuners in a digital TV. This gives users a good way to help easy channel navigation in the digital TV environment.

Performance improvement by parallel execution depends on two factors: the potential parallelism of the application itself, and the optimal mapping of the application to the target architecture, which is usually very target specific. As a case study, we analyze the expected performance of parallel execution of an H.264 encoding algorithm, known as X264, on the Cell processor. Considering the communication architecture of the Cell processor, we parallelize the algorithm at the macro-block level. From the performance analysis, we discover the overhead factors of parallel execution and estimate the expected performance. Comparison with simulation results proves the accuracy and the usefulness of the proposed analysis method.
