Abstract

Many applications in mobile and embedded systems like signal processing, ma- chine learning, kinematics, dynamics, and control depend on computationally expensive matrix operations. However, such systems underlie tight constraints regarding power consumption and physical space, which prohibits the usage of powerful multicore systems. In this paper, we propose a novel scalable and power-efficient architecture for matrix algebra in FPGA-based Systems-on-Chip. The architecture is based on a linear systolic array and has been developed with a focus on exibility in order to be adapted to different applications. We eval- uate the performance, resource utilization and power consumption of different configurations and show that it provides significant speed-ups over a mobile processor and is significantly more power efficient than a standard PC.
