| Popis: | This paper presents IMAPCAR, a 100GOPS programmable highly parallel vision processor LSI consuming less than 2 W of power for in-vehicle vision tasks of driver assistance systems. First, requirements of vision processors for driver assistance systems as well as the characteristics of vision tasks for safety are summarized. Next, features in the design of IMAPCAR are described in detail, which comparing with a previous design, improved the performance for major vision tasks by a factor of 2.5 while reduced 50% of power. Design choices taken by other in-vehicle vision processors are also compared and analyzed. Finally, technology perspectives of future in-vehicle vision processors are discussed. |
