This paper implements a 14-bit successive approximation analog-to-digital converter (SAR ADC) design. The architecture and performance of the designed ADC is described. A digital calibration algorithm applied in this ADC has been emphasized in this paper. The correction codes of the calibrated capacitor are generated from the low bit to the high bit in the correction code generation state and are...
A GPGPU-based collision detection algorithm is proposed. Firstly, the information of OBB hierarchy tree and triangles of tested objects are mapped into some data textures designed for GPGPU-based calculation, such as triangle vertex textures, bounding box size texture, tree node relationship texture, etc., then these textures are downloaded to GPU to complete the data preparation. Secondly, the whole...
