A Composable Monitoring System for Heterogeneous Embedded Platforms

Advanced computations on embedded devices are nowadays a must in any application field. Often, to cope with such need, systems designers leverage complex heterogeneous reconfigurable platforms that offer high performance, thanks the possibility of specializing/customizing some computing elements board, and usually flexible enough be optimized at runtime. In this context, monitoring system has gained increasing interest. Ideally, should non-intrusive, serve several purposes, provide aggregated information about behavior different components. However, current literature is not close ideality: For example, existing lack being applicable modern platforms. This work presents hardware intended minimally invasive performance resources, composable, capable providing user homogeneous observability transparent access components platform, so metrics can easily computed from aggregation collected information. Building previous work, article primarily focused extension an cover also specialized coprocessing units, assessment done Xilinx FPGA-based System Programmable Chip. Different explorations presented explain level customizability proposed system, tradeoffs available user, benefits respect standard de facto support made by targeted FPGA vendor.
