As the most important step of a stereo vision system, stereo matching, which finds the correspondences in stereo image pairs, requires high-quality real-time depth computation. In this paper, a high accuracy and high throughput full-pipeline hardware architecture with disparity and row parallelism is proposed. In the semi-global aggregation stage, to improve the accuracy in discontinuous regions,...
In this paper, we propose a novel implementation scheme of Discrete Cosine Transform (DCT) with ultra high area-efficiency based on signed stochastic computation. Due to the properties of stochastic computation, a new number system, complicated DCT circuits can be realized with very simple logic. According to our analysis, addition operation is the performance and hardware cost bottleneck for stochastic...
Matrix multiplication is one of the most common numerical operations in the field of scientific computing, which is the kernel routine of Level 3 BLAS. The STI CELL processor is a heterogeneous multiprocessor with a unique design to achieve high peak floating point performance. As matrix multiplication operation is essential for a wide range of numerical algorithms, so performance improvements to...
