    • A bus control and error detection system is provided for a bus system in which data and address signals are transferred between a microsequencer and a number of operational stations which are coupled to the bus. Tri-state drivers are employed in the microsequencer and in the stations which are constructed such that two of the three states of these tri-state drivers are utilized to provide the two states of binary logic operation, and the third state is a high impedance state that protects the components that are coupled to the bus during predefined abort condition which are detected in the system. An abort detection circuit is included in each of the operational stations which is coupled to receive control signals from the microsequencer and which is constructed to emit an ABORT signal output to the microsequencer when the control signals indicate that an abort condition has occurred for the associated operational station. The ABORT signal causes the tri-state driver in the microsequencer to switch to its high impedance state and the microsequencer and transmit LOCK BUS signals to all of the operational stations in order to switch their tri-state drivers to their high impedance states.

    • Logic checking circuits are provided for verifying whether or not the data bus enable logic circuits are operating properly in response to operational commands to transmit or to NOT transmit data. The transmit latches in the bus interface logic circuits are continuously monitored to determine if they are set or NOT set in a position to enable transmission of data or NOT to enable transmission of data to a bus. Transmit gating circuit means are couple to the output of said transmit latches for determining if all of the transmit latches are in the same state and are in the state ordered by the central controller, and for determining whether the state ordered by the central controller occurs in the exact time period during which the command to transmit should be executed.
    • 逻辑检查电路被提供用于验证数据总线使能逻辑电路是否响应于要发送或不发送数据的操作命令而正常工作。 总线接口逻辑电路中的发送锁存器被连续地监视,以确定它们是被设置还是不被设置在能够传输数据或不使数据传输到总线的位置。 发送门控电路装置耦合到所述发送锁存器的输出端,用于确定所有发送锁存器是否处于相同状态并且处于由中央控制器排序的状态,并且用于确定由中央控制器排序的状态是否发生在 应执行发送命令的确切时间段。

    • A system and method for detecting errors during the storage and retrieval of file information between a file cache system and a host computer system utilizes a block check sequence key as redundant data included in each block of file data transferred. The block check sequence key is generated by key generation logic and accompanies each block of file data stored in the file cache system by the host computer system. The block check sequence key is a compressed representation of the data within the selected block, as well as unique file and block identification information supplied by the requester of the write operation. When the block is retrieved from the file cache system, the system generates a new block check sequence key based on the data within the retrieved block and the unique file and block identification information supplied by the requester of the read operation. Validation logic ensures that if the retrieved key and the newly generated key does not match, an error signal is activated.
    • 用于在文件高速缓存系统和主机系统之间的文件信息的存储和检索期间检测错误的系统和方法利用块校验序列密钥作为包含在传送的每个文件数据块中的冗余数据。 块检查序列密钥由密钥生成逻辑生成,并且由主计算机系统伴随存储在文件高速缓存系统中的每个文件数据块。 块检查序列密钥是所选块内的数据的压缩表示,以及由写操作的请求者提供的唯一的文件和块标识信息。 当从文件缓存系统检索到该块时,系统基于检索到的块内的数据和由读取操作的请求者提供的唯一文件和块识别信息生成新的块校验序列密钥。 验证逻辑确保如果检索到的密钥和新生成的密钥不匹配,则会激活错误信号。
