A heterogeneous multicore SoC (System on a Chip) has been developed for HD (high-definition) multimedia applications that require secure DRM (digital rights management). The SoC integrates three types of processors: two specific-purpose accelerators for a cipher and a high-resolution video decoding; one general-purpose accelerator (MX: Matrix processor);(More)
This 600MHz single-chip multiprocessor consists of two M32R 32b CPU cores[1] and 512kB shared SRAM, and is designed for embedded microcontroller and system on chip (SoC) core. Since software for an embedded systems increases its complexity, embedded processors [2]-[4] are required to increase performance. At the same time, low power dissipation is still a(More)
The authors developed an automatically controlled manipulation system for subsea operation. The manipulation system was developed to provide inspection, cleaning and maintenance, that have been accomplished by divers, at an ocean oil exploitation platform in maximum 200 m depth under the water. The manipulator is designed to have one extension arm and two(More)
