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.

Image processing device with parallel memory access

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.

Semiconductor device and control method of semiconductor device

A semiconductor device includes a plurality of IP cores, a plurality of storage devices, a configuration information acquiring unit that acquires configuration information for specifying a timing when the IP core accesses the storage device, and an allocation determining unit that determines the storage device allocated to the IP core. The configuration information acquiring unit acquires configuration information regarding a first IP core and configuration information regarding a second IP core. The allocation determining unit determines, based on the configuration information, whether an access timing by the first IP core is the same as an access timing by the second IP core, and when it is determined that the access timings are the same, determines allocation in such a way that the storage device allocated to the first IP core becomes different from the storage device allocated to the second IP core.

Semiconductor device, allocation method, and display system

A semiconductor device includes a central processing unit and a processor on one semiconductor substrate. The processor includes a buffer for storing a first register setting list and notifies the central processing unit of an access complete signal indicating completion of reading a second register setting list within a memory. The central processing unit changes the second register setting list within the memory based on the access complete signal and notifies the processor of an update request signal. The processor reads the second register setting list changed by the central processing unit into the buffer to update the first register setting list based on the update request information.

A deaeration device for bubbling dissolved air in the cleaning liquid by cavitation is connected on a cleaning-liquid circulation path so as to bubble the dissolved air in the cleaning liquid flowing through the cleaning-liquid circulation path, and the bubbled dissolved air flows back to the cleaning tank together with the cleaning liquid so that the bubbled dissolved air is ejected from the liquid surface of the cleaning tank to the outside of the tank. Moreover, a propeller-type pump is used as the circulating pump, and the dissolved air concentration of the cleaning liquid is controlled within a range of 2.5 to 3.5 mg/l.

Deaeration device and ultrasonic cleaning device using the same

The present invention provides a technology that is implemented in a motion compensation image coding device or a coding method and intended to code motion picture data in real time by performing a decreased number of arithmetic operations so as to determine a motion vector. In motion compensation image coding, macroblocks and sub-blocks into which each of the macroblocks is divided are searched for a motion vector with integer pixel precision. Based on the results of the search, a shape of a block that should be searched for a motion vector with decimal pixel precision is determined as a shape mode. The block of the shape mode is searched for a motion vector with decimal pixel precision, whereby a motion vector needed to produce predictive image data is determined.
