    • PURPOSE: A semiconductor IC, a control method thereof, and an information processing apparatus are provided to interpret a data pattern, power noise, and correlation between the data pattern and power noise in a data error state by detecting data of a bus and a noise amount before/after a detection timing of an error. CONSTITUTION: A circuit block(210) is connected to an operation processing unit through a bus. Power noise data signal generation units(220,230,231,232) converts an analog signal of power noise, generated from power for operating the circuit block, into a digital signal. The power noise data signal generation units generate a power noise data signal. An error detecting unit(260) detects an error of data outputted from the circuit block to the bus. A write control unit(250) controls an operation of writing data on the bus and power noise information, based on the power noise data signal, in a recording unit(280). According to a detection timing of the error, the write control unit stops the writing operation.
    • 目的:提供半导体IC及其控制方法以及信息处理装置,通过检测总线的数据和噪声来解释数据模式,功率噪声以及数据模式与功率噪声之间的相关性 在错误的检测定时之前/之后的量。 构成:电路块(210)通过总线连接到操作处理单元。 功率噪声数据信号发生单元(220,230,231,232)将由用于操作电路块的功率产生的功率噪声的模拟信号转换为数字信号。 功率噪声数据信号产生单元产生功率噪声数据信号。 误差检测单元(260)检测从电路块输出到总线的数据的错误。 写入控制单元(250)控制在记录单元(280)中基于功率噪声数据信号在总线上写入数据和功率噪声信息的操作。 根据错误的检测定时,写入控制单元停止写入操作。

    • A device for controlling snoop tags is provided to require no index lock, process a read request of the same index promptly, and improve latency by entering the index to a queue and suspending the process of a replace request when the replace request is received. A snoop tag storing part(6) stores the snoop tags corresponding to contents of cache memories of a processor. A queue(2) stores way information and the index of a replace target as an entry for the replace request received from the processor. A comparator(3) compares the index stored in the queue with the index of the read request. A process based on the read request matched with the index is performed for the snoop tag storing part depending on a comparison result. The replace request is invalidated without storing the replace request to the queue if space is not found in the queue when the replace request is received. A replacing part(4) replaces the way information, which is the replace target of the read request matched with the index, with the way information of the entry matched with the index in the queue.
    • 提供了一种用于控制窥探标签的设备,以便不需要索引锁定,及时处理相同索引的读取请求,并通过在接收到替换请求时将索引输入队列并暂停替换请求的过程来改善延迟。 窥探标签存储部分(6)存储与处理器的高速缓冲存储器的内容相对应的窥探标签。 队列(2)将路由信息和替换目标的索引作为从处理器接收的替换请求的条目存储。 比较器(3)将存储在队列中的索引与读请求的索引进行比较。 根据比较结果,针对窥探标签存储部分执行基于与索引匹配的读取请求的处理。 如果在接收到替换请求时没有在队列中找到空格,则替换请求无效,而不将替换请求存储到队列中。 替换部分(4)将与索引匹配的读取请求的替换目标的方式信息替换为与队列中的索引匹配的条目的路径信息。

    • A node device, a control device, a control method and a recording medium capable of reading a computer with a control program are provided to determine whether a common node is failed or a bus connected to the common node is failed when uncorrectable data passes through the common node. A control device includes a receiving unit receiving a signal transmitting by a node when the node detects an uncorrectable error from data having an error correcting code. A judging unit judges whether the first node detects the uncorrectable error from data transmitting to a second node or not when the data transmitted from the first node is received to the second node. A stopping unit stops a process derived by a signal received from the second node when the uncorrectable error is detected in the first node. A control unit controls a display device to display a detection of the uncorrectable error existing in data detected by one node. A transmitting and receiving unit transmits and receives data comprising the error correcting code with other node.
