    • PROBLEM TO BE SOLVED: To provide a high-quality information processor.SOLUTION: An information processor comprises: a host device 1; a semiconductor memory device 2 having a nonvolatile semiconductor memory 210; and a communication path 3 that connects the host device 1 and semiconductor memory device 2. The host device 1 comprises: a first storage unit 100; and a first control unit 120 to which the first storage unit 100 and communication path 3 are connected, the control unit 120 controlling the first storage unit. The communication path 3 includes a plurality of ports to each of which a priority is assigned. The semiconductor memory device 2 is connected to the communication path 3 and includes a control unit 200 that transmits a first command including a first flag which determines the priority on the basis of a priority of the kind of data transmitted and received to and from the first storage unit 100. The first control unit 120 performs, when receiving the first command, transmission and reception of data between the first storage unit 100 and second control unit 200 via a port corresponding to the priority on the basis of the first flag.
    • 要解决的问题:提供高质量的信息处理器。解决方案:信息处理器包括:主机1; 具有非易失性半导体存储器210的半导体存储器件2; 以及连接主机设备1和半导体存储设备2的通信路径3.主机设备1包括:第一存储单元100; 以及连接有第一存储单元100和通信路径3的第一控制单元120,控制单元120控制第一存储单元。 通信路径3包括分配优先级的多个端口。 半导体存储器件2连接到通信路径3,并且包括控制单元200,该控制单元200发送包括第一标志的第一命令,该第一命令基于从第一个发送和接收的数据的类型的优先级确定优先级 第一控制单元120在接收到第一命令时,基于第一标志,经由与优先级对应的端口在第一存储单元100和第二控制单元200之间进行数据的发送和接收。

    • PROBLEM TO BE SOLVED: To provide a mechanism for interrupting access to an unauthorized address from a bus master device connected to a system bus of a processor with smaller circuit size.SOLUTION: According to a system bus type, an unauthorized address access interruption mechanism is inserted in an address line and a control line between a bus master device and a bus, or in a control circuit part of the bus. The unauthorized address access interruption mechanism includes a register for setting an address range permitting the access. Whether an address output to the address line is within this range is determined by a comparator. When the address is out of the range, the output of the control line is suppressed, whereby the unauthorized address access is interrupted.
    • 要解决的问题:提供一种用于中断从连接到具有较小电路尺寸的处理器的系统总线的总线主设备访问未经授权的地址的机制。 解决方案:根据系统总线类型,将未经授权的地址访问中断机制插入到总线主设备和总线之间的地址线和控制线,或总线的控制电路部分中。 未授权的地址访问中断机制包括用于设置允许访问的地址范围的寄存器。 输出到地址线的地址是否在此范围内由比较器确定。 当地址超出范围时,控制线的输出被抑制,从而中断了未经授权的地址访问。 版权所有(C)2013,JPO&INPIT
