  • Bit-Width Constrained Memory Hierarchy Optimization for Real-Time Video Systems

    • The great variety of pixel dynamics of real-time video processing systems, ranging from color, grayscale or binary pixels, means that a careful design and specification of bit-widths is required. It is obvious that the bit-width specification will affect the total memory storage requirement. However, what is not so obvious is that the bit-width specification will also affect the design of the memory hierarchy, an impact similar for both hardware and software implementations. We have developed an Integer Non Linear Program (INLP) formulation for the optimization of the memory hierarchy of real-time video processing systems. An active surveillance video camera is introduced as a test case. We demonstrate how the optimization model can reduce the on-chip memory storage by 61 percent compared to a non optimal memory hierarchy.

  • Polyhedral space generation and memory estimation from interface and memory models of real-time video systems
  • 2006
  • Ingår i: Journal of Systems and Software. - : Elsevier BV. - 0164-1212 .- 1873-1228. ; 79:2, s. 231-245
  • Tidskriftsartikel (refereegranskat)abstract
    • We present a tool and a methodology for estimating the memory storage requirement for synchronous real-time video processing systems. Typically, a designer will use the feedback information from this estimation to select the most optimal execution order for software processors or space to time mapping for hardware. We propose to start from a conceptual interface and memory model that captures memory usage and data transfers. This high-level modeling is provided as an extension library of SystemC called IMEM. A common polyhedral iteration space is generated from the model, where polytopes are placed using a new placement algorithm based on simple heuristics. This algorithm will ensure maximum freedom of selecting executing order as all negative dependencies are removed to the length of zero. A demonstration is given regarding how the polytopes and dependency vectors can then be used as input to a memory storage estimation tool called STOREQ.
