Ultrasound Low power WiFi with IMX7
In a wireless ultrasound probe, transmitting raw ultrasound data at high frame rates with low power consumption appears as a challenging task. On the one hand, WiFi solutions compatible with low-power embedded systems (e.g. MCUs) are typically limited to small throughputs (< 5 Mbps). On the other hand, faster WiFi modules that are optimized for high-performing SoCs (running a general-purpose OS) come with increased power consumptions. A promising solution is to use heterogeneous multicore platforms, combining the abvantages of MCUs and high-performance SoCs, and featuring efficient power-down modes.
Goal & Tasks
The goal of the mini-project is to explore a processor i.MX 7ULP from NXP) for low-power ultrasound data streaming through WiFi. In this mini-project you will:
- Program real-time domain (Cortex-M4, FreeRTOS) of IMX SoC to receive raw ultrasound data through QSPI + DMA
- Program application domain (Cortex-A7, Linux) to stream the data through WiFi.
- Test the throughput of the system and corresponding power consumption.
- Python (sklearn, tensorflow)
- Experience with Heterogeneous platforms is nice to have
