This paper presents techniques for optimization of the control part of designs generated by high-level synthesis. The concept of Behavioral Don’t Cares is dejined and algorithms for extracting behavioral don’t care conditions from a high-level description are given. These don’t care conditions are used for the optimization of the control logic and the(More)
A method is proposed for optimizing a Control I Data Flow Graph (CDFG), to generate shorter schedules, given a freed number of functional units. A counter-intuitive approach is taken of adding more operations to the CDFG to reduce the number of cycles in the final schedule. In this paper, this technique is applied to individual straight-line code sections(More)
This paper addresses relevant issues in connectivity synthesis particularly with respect to other design concerns in high-level behavioral synthesis. A restricted model is used to run a series of design experimerus to provide insight into the relationship between scheduling, conrwctivity, and placement & routing. Contrary to the common approach of counting(More)
This system uses a new added feature of performing graph transformations to shorten critical paths and reduce the number of registers necessary to implement functionally pipelined designs. it is demonstrated in this paper to yield solutions that improve upon good previously published results produced by other systems. This system also generally produces(More)
