Abstract
This work presents Chronos-V, a Many-Core System-on-Chip (MCSoC) that adopts abstract hardware mod-eling, executing the freeRTOS Operating System (OS) at each processing element (PE). The system architecture contains two regions: (i) General Purpose Processing Elements (GPPE), re-sponsible for executing user applications; (ii) peripherals that provide IO capabilities or hardware acceleration to the system. The freeRTOS kernel provides scheduling for application tasks, with modules added to it providing a Message Passing Interface (MPI) and system management. The goal is to provide a platform with a parameterizable hardware model that allows software development and evaluation of system management techniques. Results evaluate the simulation speedup by comparing the ab-stract model simulation against an RTL simulation in systems with up to 100 PEs, and thermal management techniques added to the freeRTOS as an API.
