摘要
A device having a shared memory and a method for providing access status information by the shared memory are disclosed. A digital processing device includes n processors and a shared memory. The shared memory is coupled to each processor though a separate bus, its storage area includes m common sections, and generates and outputs access status information related to whether an arbitrary processor is accessing at least one of the common sections. With the present invention, a control sequence of each processor can be simplified at a maximum by allowing the shared memory to generate and output access status information related to the common sections.
