发明名称 Memory management device.
摘要 <p>A memory management device which is connected in a virtual address space or a physical address space together with another device capable of becoming a bus master, is endowed with the function of detecting the bus request signal of the other device, interrupting an address translation process under execution and causing a processor to release a bus. Thus, the other device can be made the bus master without being kept waiting for a long time, and a system bug can be prevented which is attributed to such a fact that a wait time exceeds the data hold time of an input/output device connected to, for example, a direct memory access controller.</p>
