MIPI SoundWire: Higher Bandwidth Through Bulk Register Access

MIPI SoundWire provides an optional mechanism for transporting register operations at higher bandwidth than mandatory command mechanism.  Bulk Register Access (BRA) protocol is a particular format of data transport to achieve the higher bandwidth.  While normal commands can only be driven at the rate of one command per frame, Bulk Register Access provides the option […]

MIPI Soundwire Test Suite

Here, we describe how easy it is to integrate and validate a SoundWire design using Synopsys SoundWire VIP Test Suite. Often Verification IP and design integration require in-depth understanding of the protocol and methodology. This requires significant investment of time in building the expertise in-house. To accelerate the process, Synopsys’ Soundwire VIP solution is written in 100% […]

Benefits of MIPI Soundwire

In MIPI Soundwire: Digital Audio Simplified, we mentioned that digital audio formats, including Pulse Code Modulation (PCM) and Pulse Density Modulation (PDM), are target applications for MIPI Soundwire. Later, we discussed Digital Audio Streams and Channels. Here, we will talk about the merits MIPI Soundwire protocol has over other available digital audio interfaces. For more information on MIPI Soundwire, you can download our whitepaper Major […]

MIPI Soundwire: Digital Audio Simplified

MIPI Alliance has come up with a new protocol standard for sound interface called SoundWire. SoundWire is a robust, scalable, low complexity, low power, low latency, two-pin (clock and data) multi-drop bus that allows for the transfer of multiple audio streams and embedded control/commands. To understand its specification and design verification needs, it is important […]
