On partitioning of multistage algorithms and design of intermediate memories
M. Sauer, E. Bernard, Josef A. Nossek · 2003
Partitioning of a class of algorithms with global data dependencies, called multistage algorithms, is investigated. Partitioning requires intermediate results of computations of a specific block of the partition to be stored in an intermediate memory. Furthermore a decomposition of the global interconnection structure of the algorithm is necessary. The authors outline a design methodology for the intermediate memories which perform the data rearrangements according to the interconnection relation and that consist of locally connected synchronous modules. Additionally procedures for deriving control signals for the intermediate memory are presented, which can serve as a basis for control minimization.>
