摘要： An image processing device includes an application execution unit which executes an image processing application, an image processing circuit which performs image processing, a memory control circuit which is capable of accessing a plurality of memories and a memory allocation determination unit which determines a memory allocation of the image data on the basis of memory address management information, operation unit-specific information and application information. The application execution unit distributedly stores the image data in the plurality of memories on the basis of the memory allocation determined by the memory allocation determination unit.

摘要： In a semiconductor device, a load of CPU required for arbitration when using a shared resource is reduced.
The semiconductor device includes a CPU section and a hardware IP. In the CPU section, software modules are executed. The hardware IP includes a storage unit, an arbitration unit, and a calculation unit. The storage unit includes control receiving units that receive operation requests transmitted by the software modules, respectively. The calculation unit performs processing based on an operation request transmitted from the control receiving units. The arbitration unit controls information transmission between the control receiving units and the calculation unit so that the calculation unit receives only an operation request from any one of the control receiving units.
