Abstract

Nowadays, the modern electronic systems are facing an important limitation in terms of performance, known as von Neumann bottleneck. It affects the communications between two crucial elements, the CPU and the memory, which suffer from a saturation in bandwidth. Many solutions are currently under investigation and among them the concept of Logic-in-Memory (LiM) has been introduced: a memory enriched in its array of computational elements which enable the implementation of a flexible distributed processing system. The current work introduces Octantis, a High-Level Synthesizer useful for the exploration of LiM architectures. The proposed software analyzes an input algorithm described in standard C language and identifies which LiM architecture would implement it better. At its output, the synthesized solution is provided together with a test-bench, to properly characterize it, in terms of performance, spatial occupation and power consumption. Many algorithms have been successfully synthesized by Octantis and some of the results achieved will be discussed along the document.
