Systems and methods for delta state tracking for event stream analysis. Events at a device are tracked and stored locally or forwarded to a server. The events collectively form an event stream. When an event of interest occurs, the precise configuration of a device at the time of the event of interest can be determined by applying the event stream in chronological or reverse chronological order to a snapshot of the device's configuration. Thus, the snapshot can be taken at any time. Tracking the deltas to the device's configuration enables the precise configuration at the time of the event of interest to be determined.

A first processor for executing program code has a control interface mapped to the memory address space of a second processor and provides the second processor with direct mapped access to state information of the first processor. The first processor responds to an exception causing event to enter a halted mode stopping execution of the program code and issuing a trigger event. The second processor responds to the trigger to execute an exception handling routine during which the second processor accesses and modifies the state information via the control interface as required by the exception handling routine. On completion of the exception handling routine, the second processor causes the first processor to exit the halted mode and resume execution of the program code. Thus, the program code is physically separated from the software used to perform the exception handling routine to improve security.

A method for processing data between host computer and CPLD provides a host computer, a circuit board comprising a UART unit, a pre-debugged hardware, and a CPLD. The UART unit communicates with the host computer via UART. The method further provides the CPLD coupled between the UART unit and the pre-debugged hardware and allows the CPLD to receive data from the host computer via the UART unit and to analyze the data. According to the method, the CPLD debugs the pre-debugged hardware according to the analyzed data and obtains a result of debugging. The CPLD outputs the result and allows the CPLD to transmit the result to the host computer via the UART unit. A system using the method is also provided.

Methods, computer program products, and systems are presented. The methods include, for instance: A plurality of log messages generated while an application processes two or more workloads are collected. The application is microservice-based and each of the microservices generates respective log messages. A time domain analysis is performed to lay out respective iteration counts of the microservices of the application. Keyword patterns in the log messages are compiled and stored in a keywords database. A frequency domain analysis on the keyword patterns for respective numbers of appearances in the log messages and stored in a frequency domain analysis database. Logs generated from a new workload are automatically monitored for abnormality by comparing the logs by the new workload to the statistical pattern of keywords as established by previous workloads. For a deviation greater than a threshold, an alert is generated with issue location and delivered to preselected recipients.

A JTAG-based burning device, comprising controllable switches provided between a TDI end of a JTAG host (1) and a first chip and between every two adjacent chips, and further comprising a main controllable switch module (2) provided between each chip and a TDO end of the JTAG host (1). According to a received burning instruction, the JTAG host (1) can control an input end of a corresponding controllable switch to be connected to a corresponding output end thereof, and also control an output end of the main controllable switch module (2) to be connected to a corresponding input end thereof. Hence, the device merely needs to build a circuit to automatically adjust a JTAG link by controlling the connection relationship between the input end and the output end of the corresponding switch, achieving burning of the firmware of different chips or a combination of chips, without manual adjustment, thereby improving the test efficiency, and simplifying a circuit structure.

A multitile processing system has an execution unit on each tile, and an interconnect which conducts communications between the tiles according to a bulk synchronous parallel scheme. Each tile performs an on-tile compute phase followed by an intertile exchange phase, where the exchange phase is held back until all tiles in a particular group have completed the compute phase. On completion of the compute phase, each tile generates a synchronisation request and pauses an issue of instructions until it receives a synchronisation acknowledgement. If a tile attains an excepted state, it raises an exception signal and pauses instruction issue until the excepted state has been resolved. However, tiles which are not in the excepted state can continue to perform their on-tile computer phase, and will issue their own synchronisation request in their own normal time frame. Synchronisation acknowledgements will not be received from all of the tiles in the group until the excepted state has been resolved on the tile with the excepted state.

A processor includes an execution pipeline that includes a plurality of execution stages, execution pipeline control logic, and a debug system. The execution pipeline control logic is configured to control flow of an instruction through the execution stages. The debug system includes a debug pipeline and debug pipeline control logic. The debug pipeline includes a plurality of debug stages. Each debug pipeline stage corresponds to an execution pipeline stage, and the total number of debug stages corresponds to the total number of execution stages. The debug pipeline control logic is coupled to the execution pipeline control logic. The debug pipeline control logic is configured to control flow through the debug stages of debug information associated with the instruction, and to advance the debug information into a next of the debug stages in correspondence with the execution pipeline control logic advancing the instruction into a corresponding stage of the execution pipeline.
