Abstract: A system for internally monitoring an integrated circuit, wherein the contents of memory locations in the integrated circuit can be displayed on a dedicated display unit via a graphical interface device provided in the integrated circuit. The system provides a built-in means for observing the internal state of both firmware and hardware (as applicable) on the integrated circuit device. This facilitates the development of, and ongoing health monitoring of, the device in any system into which it may be incorporated. The provision of a graphical interface device provides a relatively high bandwidth for the outgoing data and so allows the internal state of the device to be monitored in real time.

Abstract: The invention features a system and method for installing and configuring a common software load in optical network elements. In brief overview, a configurable hardware abstraction layer (HAL) is interposed between the application software and the drivers in the common software load. With the use of a configurable HAL, network elements embodying the invention can use the same common software load for each type of card. Hence, an installer updating or originally configuring the cards in a plurality of network elements can accommodate all of the cards with the transmission of one software load. Instead of centrally tracking and organizing card specific software loads, the common software load in combination with the HAL manages the installation and upgrading process on the local card level.
