In a virtualization system that includes a hypervisor that performs OSID management for linking a plurality of OSs with resources, a guest OS that receives an initial value from the hypervisor and sets a OSID for each resource, and a OSID manager that sets a OSID for each resource, a new OSID created by OSID generator in OSID manager after a certain period of time has elapsed after setting the initial value is set to the guest OS and the IP (resource), and is requested to be updated to a new OSID set by the update controller in OSID manager. This enables simultaneous updating of OSID of the guest operating system and the resources, thus achieving high robustness.

Virtualization system and operation management method

The present invention provides a semiconductor device enabling efficient compression without increasing the circuit size and a processing method using the semiconductor device. According to an embodiment, an image processor includes: a coding circuit to perform image processing on a target image divided into a plurality of tiles, the image processing being performed on each of the tiles; a determination circuit to determine whether a tile boundary is included in the area of an image block serving as a unit of compression of the target image; and a compression circuit to compress the image block image-processed by the coding circuit, according to a determination result of the determination circuit.

Semiconductor device and method for image processing and image compression using the semiconductor device

To provide a semiconductor device which suppresses a delay in processing. The semiconductor device is equipped with a plurality of read units which read data stored across a plurality of banks in a memory having the banks, and an access method managing section which, when one of the read units reads the data, determines a read start bank number being a bank number to start reading according to operation situations of the read units excepting the one read unit, and instructs the determined read start bank number to the one read unit.
