Abstract: The application discloses a system and method for providing a compact and high speed mechanism for emulating an ASIC or other chip operating within a large computing system environment for diagnostic purposes. A two step process is disclosed for generating data patterns for fully exercising a chip and to then transmit these data patterns at a high frequency to a system under test.

Buffering the test pattern data in this manner enables the inventive system to bypass the data transmission speed limitation of the pattern generator while still employing the test patterns created by the pattern generator and to thereby test the system under test under high speed operating conditions.

Abstract: An object oriented computer apparatus and method provides a graphical user interface (GUI) for existing host-based (i.e., green screen) applications by defining some object oriented classes that reside on the client workstation, and by substituting function calls for display data in the green screen application with function calls that interface with the object oriented GUI defined by the classes. In this manner the present invention takes advantage of the processing power of client workstations in a network computing environment by having the client run the GUI. The underlying green screen application is modified to replace all display function calls with new function calls to the GUI, but this change is relatively minor and does not affect the underlying core logic of the application. In addition, the new function calls access the GUI screens directly without having to determine which screen is being displayed.

Abstract: In a data storage subsystem, drive-level processing treats data storage media as WORM by automatically advancing a write append limiter as data is written, and preventing changes to data occurring before the write append limiter. Despite this media's WORM nature, the drive-level processing permits limited overwriting of data at the end of tape since the write append limiter lags the current write location by the margin of a write allowance index. Thus, despite the drive's treatment of the media as WORM, the drive permits overwriting of trailing metadata in order to facilitate write append operations.

Abstract: A tape library system for handling multi-volume tapes includes an automated tape system with at least one tape unit and a robotic tape handling system. The tape library system receives requests from at least one host for access to a specified tape volume in a specified tape unit. The tape library system includes a tape/library control unit that receives the request from the host computer and maps the specified tape volume to a tape cartridge. The TLCU determines if the tape cartridge is currently loaded in a tape unit and, if the tape cartridge is not loaded, commands the robotic tape handling system to load the cartridge into an available unit. The TLCU forms a virtual path between the host computer and the loaded tape unit. Data is then transferred between the loaded tape unit and the host computer. Thus, the host computer is presented with a virtual view of connection to the specified tape volume loaded in the specified tape unit.

Abstract: An E2PROM controller is provided for an emulation chip. An E2PROM is connected to a CPU via a memory interconnect bus. The E2PROM and the CPU are also connected to each other via a peripheral circuit interconnect bus independent of the memory interconnect bus.

However, the E2PROM controller allows electrical communication through the peripheral circuit interconnect bus and thereby accesses the E2PROM as one of peripheral circuits. Accordingly, it is possible to check out whether or not a reprogramming program stored in the E2PROM is running normally.

Then the marked semiconductors are conveyed in a tube adapted to be loaded in an automatic mounting device such as a robot under the control of a robot controller.

Abstract: The microcontroller accesses a battery of hidden registers used essentially in the field of emulation. The fact that there is a large number of hidden registers means that it is not possible to assign them an address by which they can be accessed directly. Since this battery of hidden registers has to be accessible by a host circuit and by a microprocessor, recourse is had to a method of indirect addressing by means of two peripheral control registers. A priority signal obliges the microprocessor to wait for the read and write resources to be released by the host circuit to perform these instructions.

Abstract: Performance monitoring of network connections is an integral and necessary part of network operation, administration and management. The performance monitoring reflects the “goodness” of the communication system in supporting “high-level” data communication services to end-users.

The computer implemented process is a user-friendly, automated collection and tabulation of performance measurements that directly reflects the perception of an end-user on the capabilities of the underlying communications network. The disclosure is geared toward the “Web-centric” Internet world, but the method can be adapted to non-Internet communication systems.

Abstract: A development system includes two processors which can each act as the central processing unit of the development system. Control is passed between the processors via a system management mode (SMM) interrupt under the X86 architecture. In one embodiment, one of the processor is a processor to be emulated and the other processor is an emulating processor. Since the emulating processor runs at a much slower clock speed than the emulated processor, an application program can be run by the emulating processor until a region of interest is reached. The control of the application program can then be transferred by the SMM interrupt to the emulated processor. This arrangement allows a new compatible microprocessor to be efficiently developed using a hardware emulation system.
