An optimisation methodology for array mapping of affine recurrence equations in video and image processing
Jan Rosseel, Francky Catthoor, Hillarie Man · 2002
This paper addresses the problem of deriving optimised array architectures for real-time multi-dimensional signal processing systems, as occurring in image, speech and video applications. The starting point is a set of Weak Single Assignment Codes. For this abstract specification, we solve the difficult task of finding a globally optimised architecture with matched throughput while avoiding an explosion of the search space. The cost function not only includes the data-path area but incorporates also the crucial foreground and background memory storage. The effectiveness of our solution has been substantiated with realistic test cases.>
