Scheduler for multiple software tasks to share reconfigurable hardware

摘要

Software tasks executing on a computer system, such as run-time applications in a real-time operating system (RTOS), are scheduled with respect to requested use of a reconfigurable hardware device on the system. Configuration data associated with the software tasks may be loaded or unloaded based on a priority level associated with the device request, the time of the request, and the current state of the configuration memory of the device. Additionally, statistics regarding device usage and application execution history are used to anticipate a device request from a software task, and to preemptively load configuration data for the software task into the configuration memory of the device.
