A method determines a configuration for inter-processor communication for a heterogeneous multi-processor system. The method determines at least one subgraph of a graph representing communication between processors of the heterogeneous multi-processor system. For each subgraph the method (i) determines a plurality of subgraph design points. Each subgraph design point has a variation of channel mapping between any two of the processors in the subgraph by selecting from first-in-first-out (FIFO) memory and shared cache, and varying the shared cache and a local memory associated with at least one of the processors according to the channel mapping; and (ii) selects a memory solution for the subgraph, based on a cost associated with the selected memory solution. The method then determines a configuration for the graph of the heterogeneous multi-processor system, based on the selected memory solutions, to determine the configuration for inter-processor communication for the heterogeneous multi-processor system.

Memory configuration for inter-processor communication in an MPSoC

Disclosed herein is a method for identifying a constellation of alignment marks within an arrangement of computer readable marks in an image (), the arrangement of computer readable marks () including alignment marks (-) and data carrying marks (-). The alignment marks (-) define a reference grid within the arrangement of computer readable marks and the data carrying marks (-) are modulated with respect to the reference grid to encode data. The method selects at least two marks () from the arrangement of computer readable marks and determines a rotation center with reference to the selected marks (). The method then determines rotated positions for the selected marks by rotating each of the selected marks by a predetermined angle about the rotation center. For each rotated position, a mark having a position that is less than a predetermined threshold from the rotated position is located from the arrangement of marks and then the selected marks and the located marks are identified as the constellation of alignment marks.
