To address the need to quickly, cost-effectively and reliably develop software to control science instruments deployed on spacecraft, QuickFlex proposes to create a payload control (QuickDirect) software package that can be used by instrument developers as a template for specific missions. QuickDirect will address the generic needs of science instrument control and will provide a template for the control of mission specific detectors and mechanisms. It will contain modules for command & telemetry handling, engineering data collection and monitoring, memory upload and downloads, and software and hardware watch dog maintenance. QuickDirect will contain common command and telemetry interfaces (serial, UART, Mil-Std-1553-B) as well examples of mechanism and detector control modules. QuickDirect provides a template for the development of the specific instrument control software, freeing the QuickDirect user to focus on the interfaces and specialized processes that are specific to the detectors and mechanism, knowing that the generic payload control requirements are fully and effectively covered. While the software package is designed to operate on a processor platform dedicated to operation of the instrument, the software itself is not tied to any specific operating system or platform. Notably, QuickDirect will leverage the QuickFlex Reconfigurable Logic Manager (RLM), a set of proven software that enables simple and effective exploitation of the full range of capabilities offered by field programmable gate array (FPGA) devices, including partial dynamic reconfiguration. The QuickDirect software package will be thoroughly reviewed, tested and documented.
