    摘要: A multiprocessor system (10) includes a plurality of processing modules, such as MPUs (12), DSPs (14), and coprocessors/DMA channels (16). Power management software (38) in conjunction with profiles (36) for the various processing modules and the tasks to executed are used to build scenarios which meet predetermined power objectives, such as providing maximum operation within package thermal constraints or using minimum energy. Actual activities associated with the tasks are monitored during operation to ensure compatibility with the objectives. The allocation of tasks may be changed dynamically to accommodate changes in environmental conditions and changes in the task list. Temperatures may be computed at various points in the multiprocessor system by monitoring activity information associated with various subsystems. The activity measurements may be used to compute a current power dissipation distribution over the die. If necessary, the tasks in a scenario may be adjusted to reduce power dissipation. Further, activity counters may be selectively enabled for specific tasks in order to obtain more accurate profile information.

    摘要: A base for a multi-chip module that provides for built-in testability. Active test components are embedded in a module substrate. These test components primarily consist of boundary scan cells that comply with the IEEE 1149.1 test standard. The scan cells are connected to each other, and are connected to interconnection paths among chips and to individual chips, thereby partitioning the module into testable partitions. These partitions permit testing of chip interconnections, chip functionality, and module functionality. Scan cell connections may be mask programmable so that the same multi-chip module base can be used for many different multi-chip module configurations.

    摘要: A wafer-scale assembly apparatus for integrated circuits and a method for forming the wafer-scale assembly are disclosed. A semiconductor wafer including a plurality of circuits is provided with a plurality of metal contact pads as electrical entry and exit ports. A first wafer-scale patterned polymer film carrying solder balls for each of the contact pads on the wafer is positioned opposite the wafer, and the wafer and the film are aligned. The film is brought into contact with the wafer. Radiant energy in the near infrared spectrum is applied to the backside of the wafer, heating the wafer uniformly and rapidly without moving the semiconductor wafer. Thermal energy is transferred through the wafer to the surface of the wafer and into the solder balls, which reflow onto the contact pads, while the thermal stretching of the polymer film is mechanically compensated. The uniformity of the height of the liquid solder balls is controlled either by mechanical stoppers or by the precision linear motion of motors. After cooling, the solder balls solidify and the first polymer film is removed. The process is repeated for assembling sequentially a wafer-scale patterned interposer overlying all of the solder balls and the wafer and contacting each solder ball with a soldered joint, and a second wafer-scale patterned film carrying solder balls contacting the interposer. In each process, the wafer is heated uniformly and rapidly and without moving it, the alignment is maintained during heating by mechanically compensating for the thermal stretching of the polymer film, and the uniformity of the height of the liquid solder balls is controlled by mechanical stoppers or position closed-loop linear actuators. The second film is removed after cooling. Other embodiments are also disclosed.

    摘要: A predictive power regulation apparatus and method that minimizes power and ground bounce in a logic device. The apparatus includes a predictor and a voltage or current smoothing device connected to the predictor. The voltage or current smoothing device outputs adjusted voltage or current to power and ground planes of the logic device. In one embodiment, the predictor includes an instruction scanner device and a look-up table connected to the instruction scanner device. The instruction scanner device determines the next instruction to be executed by the logic device. A voltage/current scheduling buffer connected to the look-up table contains voltage and current compensation and the time at which the voltage or current compensation should be requested from the voltage or current smoothing device. An alternative predictive power regulation apparatus is described that reduces power and ground bounce caused by the I/O buffer circuitry switching in the logic device.
