+## Board Layer for Corstone-300 FVP
+
+Device: SSE-300-MPS3
+
+### 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)
+| Driver_vStreamVideoOut | RGB888 video,          resolution  480 x 800 (W x H)
