Abstract

Programmable artificial retinas (PAR) are image sensors with a digital processor in each pixel. PAR based vision systems are our framework. In its basic version, a PAR operates in SIMD mode, which restricts it to low level vision only. To support higher levels of vision, non-SIMD operators have to be settled in each pixel. Programmable connections and asynchronous communications are key ingredients to support regional computations, but under which form? To identify the good ones, we consider adding pixel data simultaneously over different regions as an exemplary primitive. After recalling previous implementations, we propose a novel one based on a tree extension of micro-pipelines that we call convergent micro-pipelines.
