A drone taxi combines the data from a satellite and a cellular basestation.

Introduction

We are currently working on designing Radio Frequency (RF) Systems on a chip (SoCs) for the Internet of Things (IoT). Requirements for these devices often include data connectivity and location information. We want to integrate both functionalities on a single chip. Positioning and network synchronization rely on performing a large number of cross-correlations in real-time. Due to the large throughput requirements, large accelerators are required. Instead of using a dedicated circuit for each standard, we would like to share a single, flexible accelerator for all these tasks.


Project Description

Concept for the shared correlation accelerator

The goal of this project is, to develop a shared correlation accelerator for our RF SoC. This unit should support both positioning, as well as the synchronization for NB-IoT and eMTC. To do this, you will study the algorithms to quickly calculate a large number of cross-correlations. Using this knowledge, you will develop the accelerator in VHDL, or using High-Level Synthesis (HLS). It should be able to meet the throughput requirements of 100M correlation results/s, while keeping the area as low as possible.

Once you have implemented and verified the unit, you may tape out your own chip, or test it in our FPGA testbed.
