Abstract

A formalized method and a design system are described for part of the design decisions, related to memory, involved while designing an essentially digital device. The method and system determine an optimized memory organization starting from a representation of said digital device, the representation describing the functionality of the digital device and comprising data access instructions on basic groups, which are groups of scalar signals. The method and system determine optimized scheduling intervals of said data access instructions such that execution of said functionality with the digital device is guaranteed to be within a predetermined cycle budget, the determining of the optimized scheduling intervals comprising optimizing access conflicts with respect to an evaluation criterion related to the memory cost of said digital device. An optimized memory organization is selected in accordance with the optimized scheduling intervals and the optimized access conflicts.
