Title: DATA SYNCHRONIZATION FOR IMAGE AND VISION PROCESSING BLOCKS USING PATTERN ADAPTERS
Abstract:
In described examples of a hardware thread scheduler (311) for a multiprocessor system, the scheduler (311) is configured to schedule processing of multiple threads of execution by resolving data dependencies between producer modules and consumer modules for each thread. Pattern adaptors (654) in the scheduler (311) allow mixing of multiple data patterns across blocks of data. Transaction aggregators (655) allow re-using image data by multiple threads of execution while the image data remains in a given data buffer. Programmable delays (656) provide bandwidth control on initiation of thread execution. Watchdog timers (657) provide failure and hang detection.
