Rockchip RK628D based HDMI-to-MIPI-CSI board converts HDMI video into camera feed for embedded systems

Firefly HDMI to MIPI CSI adapter board

The Firefly HDMI-to-MIPI-CSI converter board converts an HDMI video and audio source into a MIPI-CSI camera stream for supported Rockchip SoCs, which is the complete opposite of the Olimex MIPI-HDMI adapter that converts MIPI DSI display signals to HDMI output. Built around the Rockchip RK628D video bridge chip, the board supports HDMI 1.4/2.0 input with 8-bit and 10-bit video, RGB888 and YUV420 color formats, and resolutions up to 4K @ 60fps. On the output side, it provides a MIPI-CSI interface compliant with MIPI D-PHY v1.2, with video output in YUV422 color format, supporting resolutions up to 4K @ 30fps. Audio output is available through a 3.5 mm headphone jack and onboard pin headers, making the board suitable for HDMI capture, smart display, micro-projector, and embedded video conversion applications.

MIPI SoundWire I3S (SWI3S) targets high-bandwidth, low-latency audio applications

MIPI SWI3S vs SLIMbus vs SoundWire

The MIPI Alliance has recently released the SoundWire I3S (MIPI SWI3S v1.0) specification for high-bandwidth, low-latency audio applications which unify control and data over a single, power-efficient interface. SWI3S builds upon the two-pin, multi-drop architecture of MIPI SoundWire released in 2014, and offers higher bandwidth, low power consumption, much better noise immunity, and support for scalable multi-device topologies to meet the increasing requirements of embedded audio systems. MIPI SWI3S v1.0 supports data rates up to 76 Mbps against 24 Mbps for the earlier SLIMbus and SoundWire audio interfaces, and improves noise immunity by operating in “forwarded clock” or “differential low voltage signaling”. It also implements a range of new features such as Hubs, multiple PHY support, control CRC, power-saving techniques, and more. MIPI SoundWire I3S key features: Transports audio data, control commands, interrupt signals, and synchronization information over a unified two-pin link Forwarded bit clock single-ended (FBCSE) and differential low-voltage […]

MIPI C-PHY v3.0 released with 18-Wirestate mode encoding increasing the per-lane performance by up to 35 percent

MIPI C-PHY v3 0 18-wirestate encoding

The MIPI Alliance has recently released the MIPI C-PHY v3.0 specification, defining the physical layer for connecting cameras and displays. The main change in MIPI C-PHY Version 3.0 is the addition of an 18-Wirestate mode encoding option – instead of the 6-Wirestate mode encoding used in previous versions – that increases the maximum performance of a C-PHY lane by approximately 30 to 35 percent. The MIPI Alliance claims this enhancement delivers up to 75 Gbps over a short channel for ultra-high-resolution image sensors. The table below shows the key features and differences between versions of the MIPI C-PHY specification. Interestingly, the symbol rate decreased for MIPI C-PHY v3.0 compared to v2.1 (7.0 Gsps vs 8.0 Gsps for short channel), but the data rate increased from 18.3 to 24.9 Gbps, a 36% increase, due to the more efficient encoding option 32b9s that transports 32 bits over nine symbols (3.56 bits per symbol) while maintaining […]

Synaptics Astra SR series Arm Cortex-M55 MCUs feature Arm Ethos-U55 NPU, low-power Cortex-M4 core with microNPU

astra sr series featured image

Synaptics unveiled an extension to its Astra Native AI platform with the new SR series of MCUs. This new product family, unlike the Astra SL series released last year, isn’t comprised of Linux-capable application processors. Instead, the Arm Cortex-M55 microcontrollers focus on providing high-performance, AI-native processing for Edge AI applications leveraging a built-in Arm Ethos-U55 NPU. Built on the Arm Cortex-M55 core and the Arm Ethos-U55 neural processing unit (NPU), these MCUs are optimized for multimodal applications, including vision, audio, and voice processing. As indicated in the MCU’s block diagram (see below), the SR series also features an optional low processing SoC unit featuring an Arm Cortex-M4 @ 100MHz and a Synaptics micro NPU engine. Such a provision in this MCU is what allows the three operation tiers the company offers with the MCU series: performance, efficiency, and ultra-low-power modes, allowing intelligence across various power levels. The MCU can switch […]
