A method, system, and computer-usable medium for implementing a programmable DMA master with data checking utilizing a drone system controller. According to an embodiment of the present invention, a drone processor generates a collection of random data and stores a first and second copy of the collection of random data in a first and second memory location in a drone memory. The drone processor writes a third copy of the collection of random data in a processor memory. When the drone processor retrieves the third copy from the processor memory, the drone processor writes the third copy in the second memory location in the drone memory. When the drone processor compares the first copy with the third copy, the results of the compare is written in a status location within the drone processor.

Implementing a programmable DMA master with write inconsistency determination

A test system includes a debugging system and a system under test (SUT). The debugging system includes a debugging processor that couples to an SUT processor in the SUT via a memory mapping interface bus therebetween. In one embodiment, the debugging processor operates as a master to conduct test operations on the SUT via the memory mapping interface bus. The debugging processor and the SUT processor operate together in a cluster mode to provide non-invasive debugging of the (SUT) while the SUT executes application software in a real time environment.

A system, apparatus, computer program product and method of performing functional validation testing in a system are provided. Generally, functional validation testing includes data acquisition and data validation testing. During the functional validation testing two devices may be exchanging data. The exchange of data by the two devices may be referred to as data acquisition. The data from one device and the data from the other device may be compared to each other. This may be referred to as data validation. When data is exchanged during data acquisition, it is also stored in appropriate locations in a pool of buffers in memory. During the data acquisition, checks are made to determine if the system is entering an idle cycle. If so, the data validation test is performed by using the data in the pool of buffers in memory.

System, apparatus and computer program product for performing functional validation testing

A method, device, system, and computer program product for enabling advanced control of debugging processes on a JTAG (Joint Test Action Group) IEEE 1149.1 capable device (or system under test (SUT)). Middlesoft Commander is provided within a JTAG-enabled (or JTAG) POD, which is connected to both a host system executing debugging software and the SUT. The communication between the POD and the SUT is enabled with a pair of JTAG interfaces bridging the connection between the POD and the SUT. Middlesoft Commander comprises code that enables Middlesoft Commander to convert high level commands (debug packets) received from (or generated by) the host system into JTAG commands. These JTAG commands are forwarded to the SUT. Middlesoft Commander further comprises code that enables Middlesoft Commander to convert the JTAG data received from the SUT into commands recognizable by the host system.

A system, apparatus, computer program product and method of performing operational validation on a system are provided. The system may include a CPU with a cache, a communications network, and a plurality of devices exchanging data during a test. When the test is ready to be performed, the CPU may set up a pool of buffers in the cache. The pool of buffers may generally have a set of locations corresponding to locations in an actual destination buffer and a set of locations corresponding to locations in an actual source buffer. During the performance of the test, data is exchanged over the communications network to and from the source and destination buffers. Snooping logic in the cache may snoop data on the communications network. The data snooped may be entered in appropriate locations in the pool of buffers. This allows the CPU to perform operational validation by using cached data instead of data that is in the actual source and destination buffers.

Method and program product operable on a computer for changing configuration/setup parameters in an embedded controller type X86 based computer system, the system characterized by the absence of any keyboard or video display, from a remote terminal. The power on self test sequence is modified to produce an externally detectable audio-visual signal indicating potential access through a port as an aspect of communicating configuration/setup from the remote terminal. Communication is established through the port of the embedded controller using a refined interrupt which selectively accepts keyboard data entered at a remote terminal and translates that data into configuration/setup parameters for the embedded controller. Similarly, configuration/setup menu and the like information generated in the embedded controller is intercepted by a refined interrupt, filtered in graphical content for alpha numeric characters, and restructured into data transmittable from the port of the embedded controller to the remote terminal. To change configuration/setup parameters, the operator connects the remote terminal cable to the embedded controller port, initiates a power on self test mode, detects an audio-visual response indicating a window of access to change the configuration/setup parameters, enters the appropriate control signals to initiate the change, and thereafter interacts with the remote terminal display and keyboard to change the configuration/setup parameters as if accomplished local to the embedded controller.
