Board: Arm SSE-320

Board Layer for Corstone-320 FVP

This layer works for:

  board: ARM::SSE-320
  device: ARM::SSE-320-FVP

System Configuration

System Component Setting
Heap 768 kB (configured in linker file)
Stack (MSP) 32 kB (configured in linker file)

STDIO mapping

STDIO is routed to terminal via UART0 peripheral

CMSIS-Driver mapping

CMSIS-Driver Peripheral Connection
Driver_USART0 UART0 STDIN, STDOUT, STDERR
CMSIS-Driver VIO VIO CMSIS_VIO
Driver_vStreamAudioIn VSI0 CMSIS_VSTREAM_AUDIO_IN
Driver_vStreamAudioOut VSI1 CMSIS_VSTREAM_AUDIO_OUT
Driver_vStreamVideoIn VSI4 CMSIS_VSTREAM_VIDEO_IN
Driver_vStreamVideoOut VSI6 CMSIS_VSTREAM_VIDEO_OUT

CMSIS-Driver Virtual I/O mapping

VIO driver interfaces with the arm_vio.py Python stub implementation which stores and loads signal values.

CMSIS-Driver vStream configuration

Driver Stream Format Description
Driver_vStreamAudioIn 16-bit PCM audio, 16000 samples/second
Driver_vStreamAudioOut 16-bit PCM audio, 16000 samples/second
Driver_vStreamVideoIn RGB888 video, resolution 1280 x 720 (W x H)

Python Requirements

vStream Audio and Video implementations for VSI depend on PyAudio and OpenCV libraries for Python. Use requirements.txt to install required Python packages:

  • opencv-python
  • PyAudio
pip install -r requirements.txt
