Abstract:
A system for automatic hardware ZLW insertion for IPU image streams is described herein. The system includes a memory and a processor. The memory is to store imaging data. The processor is coupled to the memory. The processor is to receive an image stream request and determine a data transfer type. The processor is also to insert a zero length write (ZLW) instruction ahead of the image stream request in response to the image stream request beginning on a different page when compared to the current page in a page history. Additionally, the processor is to insert a ZLW instruction ahead of the image stream request in response to the image stream request crossing a page boundary.
