E. Lettang

About

E. Lettang is a pioneer in algorithm-specific integrated circuit (IC) design, with a career focused on bridging the gap between high-level behavioral descriptions and physical silicon implementation. Their most influential work centers on the LAGER system, an integrated CAD framework that revolutionized how engineers design custom chips for demanding applications like speech processing, image processing, telecommunications, and robot control. The seminal 1991 paper on LAGER, which has garnered 96 citations, introduced a transformative approach by providing user interfaces at behavioral, structural, and physical levels, enabling designers to generate chips directly from behavioral descriptions combined with parameterized structural templates. This work, further refined in a 2003 follow-up (26 citations), established a behavioral mapper and silicon assembler that dramatically streamlined the design flow. Lettang’s contributions have had a lasting impact on the field of electronic design automation, empowering researchers and engineers to rapidly prototype algorithm-specific ICs without deep expertise in low-level hardware design. Their legacy remains a cornerstone for anyone exploring the intersection of algorithms and custom silicon.
