摘要： A vertex shader. The vertex shader comprises an instruction register file, a flow controller, a thread arbitrator, and an arithmetic logic unit (ALU) pipe. The instruction register file stores a plurality of instructions. The flow controller concurrently executing a plurality of threads, reads the instructions in order from the instruction register file for the threads and accesses vertex data for the threads. The thread arbitrator checks the dependency of instructions in the threads and selects the thread to execute in accordance with the result of the dependency check and a thread execution priority. The arithmetic logic unit (ALU) pipe receives the vertex data for executing the instructions of the thread selected by the thread arbitrator for three-dimensional (3D) graphics computations.

摘要： An accumulating operator is applicable to a digital data processor to realize an output floating point number in response to a first floating point number and a second floating point number. The accumulating operator comprises a splitter dividing the first floating point number into a third floating point number and a compensation number, wherein an exponent of the third floating point number is equal to or greater than the exponent of the second floating point number; an accumulator electrically connected to the splitter for operating the second and third floating point numbers to realize a fourth floating point number; and a compensator electrically connected to the splitter and the accumulator for operating the fourth floating point number and the compensation number to realize the output floating point number. Via compensation, the precision of the floating point operation can be improved.

摘要： An embedded device including a random access memory (RAM) and a processor is provided. The processor includes a processor core and an authentication module. The RAM stores data-to-be-authenticated. The data includes a program code to be executed by the processor core. The authentication module periodically accesses and authenticates the data-to-be-authenticated in the RAM. When the authentication module deems that the program code in the RAM loses its integrity, the authentication module interrupts the processor from further executing the program code.

摘要： The texture engine, provided in this disclosure, comprises a texel location calculator, a texture cache unit, and a video processing unit. The texel location calculator receives a texture and video request for a pixel, including location information of texture data for the pixel in a texture map stored in a memory unit and information of video processing required for the pixel. The texel location calculator computes memory addresses of the texture data in the memory unit and graphics data required for the pixel when performing the video processing specified in the texture and video request in the memory unit. The texture cache unit retrieves a copy of the graphics data and texture data from the memory unit with the memory addresses computed by the texel location calculator. The video processing unit receives the graphics data to perform the video processing specified in the texture and video request on the graphics data.
