Abstract
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.
