This paper defines a multiple resolution representation for the two-dimensional gray-scale shapes in an image. This representation is constructed by detecting peaks and ridges in the difference of lowpass (DOLP) transform. Descriptions of shapes which are encoded in this representation may be matched efficiently despite changes in size, orientation, or(More)
<italic>This paper describes the REAL REgister ALlocation program. REAL uses a track assignment algorithm taken from channel routing called the Left Edge algorithm. REAL is optimal for non-pipelined designs with no conditional branches. It is thought that REAL is also optimal for designs with conditional branches, pipelined or not. Experimental results are(More)
Acknowledgments I could not have completed this research without the guidance, support, friendship, and love of many. I am very delighted to express my sincere gratitude. First, I would like to thank my advisor Prof. Alice Parker. From the very beginning, she trusted me and guided me as I explored my own ideas. Along the way, she trained me to think deeper(More)
This paper describes a set of techniques for the synthesis of pipelined data paths, and presents Sehwa, a program which performs such synthesis. The task includes the generation of data paths from a data flow graph along with a clocking scheme which overlaps execution of multiple tasks. Some examples which Sehwa has designed are given. Sehwa can find the(More)
Heterogeneous systems can achieve enhanced performance and/or cost-effectiveness over homogeneous systems. SOS, a formal method to synthesize optimal heterogeneous systems for given applications, involves creation and solution of a mixed integer-linear programming model. A primary component of the model is the set of relations to be satisfied to ensure(More)
