Heterogeneous systems-on-chip empower all modern intelligent systems. We start by explaining the implications of the ever-increasing variety of specialized accelerators present in SoCs: the price for the efficiency gain they offer is the complexity of system integration. To address this challenge, we developed Embedded Scalable Platforms. By combining a scalable architecture with a system-level methodology, ESP simplifies the design of individual accelerators and automates their hardware/software integration. First, we discuss the properties of ESP that are key for open-source hardware, including flexibility, modularity, scalability and reusability. Then, we demonstrate the main features of the open-source ESP infrastructure, including integration of third-party RISC-V cores and accelerators developed with various design flows (high-level synthesis, Chisel, RTL), system-level ESP services for managing heterogeneity, and reconfigurable cache-coherence models for accelerators. Finally, we illustrate the ESP software-stack templates that enable system-level simulation for testing accelerators with bare-metal applications and full-system FPGA-based emulation for software development. Biographies: Luca P. Carloni is Professor of Computer Science at Columbia University in the City of New York. He holds a Laurea Degree in Electronics Engineering from the University of Bologna and the MS and PhD degrees in Electrical Engineering and Computer Sciences from UC Berkeley. His research interests are in system-on-chip platforms and distributed embedded systems. He coauthored over one hundred and forty refereed papers. Luca received the NSF CAREER Award, the ONR Young Investigator Award, and an Alfred P. Sloan Research Fellowship. In 2013, Luca served as general chair of Embedded Systems Week. Luca is an IEEE Fellow. Giuseppe Di Guglielmo received the Laurea degree (summa cum laude) and the PhD degree in Computer Science from the University of Verona, Italy in 2005 and 2009, respectively.
