摘要： A hardware thread scheduler (HTS) is provided for a multiprocessor system. The HTS 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 may be provided in the scheduler that allows mixing of multiple data patterns across blocks of data. Transaction aggregators may be provided that allow re-using the same image data by multiple threads of execution while the image date remains in a given data buffer. Bandwidth control may be provided using programmable delays on initiation of thread execution. Failure and hang detection may be provided using multiple watchdog timers.

摘要： A method for geometrically correcting a distorted input frame and generating an undistorted output frame includes capturing and storing an input frame in an external memory, allocating an output frame with an output frame size and dividing the output frame into output blocks, computing a size of the input blocks in the input image corresponding to each output blocks, checking if the size of the input blocks is less than the size of the internal memory and if not dividing until the required input block size of divided sub blocks is less than the size of the internal memory, programming an apparatus with input parameters, fetching the input blocks into an internal memory, processing each of the divided sub blocks sequentially and processing the next output block in step until all the output blocks are processed; and composing the output frame for each of the blocks in the output frame.
