摘要： A history module for monitoring plural components in an embedded disk controller with a first main processor operationally coupled to a first bus and a second processor operationally coupled to a second bus is provided. The history module includes an event control module that receives break point conditions that stops the history module from recording information of a component; and a first register that allows selection or-de-selection of certain components in the embedded disk controller. The first register can also store a trigger mode value, which specifies a number of entries that are made in history module buffer(s) after a break point condition is detected.

摘要： 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.

摘要： A plurality of transmitting and receiving elements are coupled between read and write buses. The communication paths which connects the tranmitting and receiving elements to the buses are each provided with a fault indicating circuit in series therewith. Each of said fault indicating circuits have logic gating means which include a bit register for each of the bits of a data byte and a parity bit. The output of the bit register means are coupled to isolation drivers which in turn are connected to parity checking circuits and the buses for indicating errors which occur in the bytes of a data word without degrading or delaying data transmission to and from said read and write buses.

摘要： 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.

摘要： 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.
