SYSTEM-ON-CHIP DEVICE, METHOD OF PERIPHERAL ACCESS AND INTEGRATED CIRCUIT

摘要

A system-on-chip device (100) comprises a core supporting a first virtual machine image (110) and a virtual machine monitoring unit (114) capable of communicating with the first virtual machine image (110). A shareable resource is also provided as well as a conflict detection unit (300) capable of communicating with the virtual machine monitoring unit (114) and the first virtual machine image (110). The conflict detection unit (300) is arranged to detect, when in use, an access conflict caused by more than one virtual machine image attempting to access initially the shareable resource (116). The conflict detection unit (300) is arranged to refer, when in use, the access conflict in response to detection thereof to the virtual machine monitoring unit (114) for resolving of the access conflict, thereby handling the access conflict before the virtual machine monitoring unit (114).
