PULP - An Open Parallel Ultra-Low-Power Processing-Platform
This is a joint project between the Integrated Systems Laboratory (IIS) of ETH Zurich and the Energy-efficient Embedded Systems (EEES) group of UNIBO to develop an open, scalable Hardware and Software research platform with the goal to break the pJ/op barrier within a power envelope of a few mW.
The PULP platform is a multi-core platform achieving leading-edge energy-efficiency and featuring widely-tunable performance. The aim of PULP is to satisfy the computational demands of IoT applications requiring flexible processing of data streams generated by multiple sensors, such as accelerometers, low-resolution cameras, microphone arrays, vital signs monitors. As opposed to single-core MCUs, a parallel ultra-low-power programmable architecture allows to meet the computational requirements of these applications, without exceeding the power envelope of a few mW typical of miniaturized, battery-powered systems. Moreover, OpenMP, OpenCL and OpenVX are supported on PULP, enabling agile application porting, development, performance tuning and debugging.
