Huge texture is an important component in many civil and military simulations. These textures are often too large to fit into video memory, even system memory, causing a bottleneck. In this paper, we present an efficient large texture management technique which is inspired by clip map. The clipmap algorithm caches a subset of the texture mipmap pyramid in video memory and updates incrementally based...
In this letter, a new decomposition algorithm of type-IV discrete cosine transform/type-IV discrete sine transform (DCT-IV/DST-IV) and architecture of a hardware accelerator for realizing fast inverse modified discrete cosine transform (IMDCT) computation are presented. The comparisons of computational complexity with some well-known algorithms show that the proposed algorithm possesses the advantages...
A design of three-axes high speed engraving machine control system based on embedded system was proposed in this paper. ARM (advanced risk machines) and FPGA (field programmable gate array) were considered as the corn in hardware, as well as the real-time multitask operating system muc/OS-II as platform in software system. One new solution for high speed engraving machine control system was provided,...
