High-level synthesis is becoming increasingly important in the area of
VLSI CAD. During the last decade, much research has been carried out
in this area and some results have been achieved. This paper presents
a survey on the slate-of-the-art of current high-level synthesis resea
rch and applications. Besides basic knowledge, a comprehensive overvie
w has been conducted among the various theories, methods, algorithms,
and applications of the existing systems. Their advantages, limitation
s, and feasibilities are also described. Finally, some points on curre
nt status and future directions of high-level synthesis are addressed.
