Tops Systems Corp of Japan, a venture involved in multicore technology, together with Toyota Motor Corp and Nihon Unisys Ltd, both of Japan, is developing a dedicated integrated circuit (IC) for ray tracing*, an image rendering method used in 3D computer graphics (3D CG) processing. A total of 73 heterogeneous cores designed specifically for ray tracing operations will be single-chipped, and nine of these chips interconnected (see Fig). With high-definition (HD) resolution at 1920 x 1080 pixels, the target processing speed is 800 tera floating point operations per second (TFLOPS).
