End-to-end QoS for the open source safety-relevant RISC-V SELENE platform Andreu Cerezo, Pablo Hernández Luz, Carles Picornell Sanjuan, Tomás López Rodríguez, Pedro Alcaide Portet, Sergi Bas Jalón, Francisco Benedicte Illescas, Pedro Chang, Feng Cabo Pitarch, Guillem Fuentes Díaz, Francisco Javier Abella Ferrer, Jaume Universitat Politècnica de Catalunya. Doctorat en Arquitectura de Computadors Barcelona Supercomputing Center Àrees temàtiques de la UPC::Informàtica::Arquitectura de computadors High performance computing Real-time data processing Multiprocessors Càlcul intensiu (Informàtica) Temps real (Informàtica) Multiprocessadors This paper presents the end-to-end QoS approach to provide performance guarantees followed in the SELENEplatform, a high-performance RISC-V based heterogeneous SoC for safety-related real-time systems. Our QoS approach includes smart interconnect solutions for buses and NoCs, along with multicore interference-aware statistics units to, cooperatively, achieve end-to-end QoS.
