If your low-end device has 500MHz DSP MIPS, how would you use it? I think developers often use these computing powers to add some new and amazing features or to add some power-saving features that high-end equipment vendors have. In recent years, developers have done a lot of DSP customization work to help mobile phone manufacturers to differentiate in audio, voice and image, because these areas are where DSP works. . . .

In recent years, developers have done a lot of DSP customization work to help mobile phone manufacturers to differentiate in audio, voice and image, because these areas are where DSP works. But today's Qualcomm® SnapdragonTM family of chips is equipped with the Qualcomm® HexagonTM DSP, which gives low-end devices the power to do so, allowing developers to take advantage of these powerful computing powers to do something new.
Ecosystem for affordable equipment
I wrote an article about NXP Software a few months ago. The company migrated the capabilities of voice processing and sound sensors to the Hexagon, resulting in faster computing speeds and lower power consumption in CPU computing. Now, more and more developers like NXP Software are aware of the huge opportunities hidden in affordable devices.
NXP Software feels that Hexagon works well. The software tools in the Hexagon SDK are very helpful for us to customize the DSP. As more Opteron processors begin to support DSP, we hope to further integrate our LifeVibes VoiceExperience speech enhancement software and AudioSense sound sensor with these processors. The Qualcomm Developer Community website has really helped developers use Opteron processors for efficient design.

As Qualcomm began to ship Hexagon processors on Snapdragon 425, 618 and 620 processors, the opportunities in low-end devices are rapidly increasing. Developers can now offer handset manufacturers the differentiated features available on current high-end devices on low-end devices.
Below is a list of the members of this ecosystem and the ways they are helping mobile phone manufacturers such as Samsung, OnePlus and OPPO to offer differentiated technologies:
Audio Processing for Music Playback - AM3D, Audyssey, Cirrus Logic, Dolby DTS, ForteMedia, Harman-Kardon, Maxsound, Maxim, NXP, Yamaha, Waves
Camera - Almalence, Arcsoft, Athentech, Lytro, Omnivision, Pixart, SONY Sensors
Computer Vision – Omron, Morpho
Sensors - AKM, ALPS, AMS, ADI, Avago Tech, Bosch, Capella, Epcos, Fairchild, Fingerprints Inc., Freescale, Intersil, Invensense, Kionix, LiteOn, Maxim, Memsic, uRATA, Partron, Rohm, PNI Sensor, Sensirion, Sensor Tek, Shindu Micro ST, TSC Corp Voltafield, ZDMI
Voice aspects - Audience, Audyssey, Arkamys, Fortemedia, ImaginaTIon Technologies, Mighty Works, Nuance, NXP, Sensibol, Storacall, TIP SoluTIons, Transono
What can developers get in this ecosystem?
When I talked to developers about the Hexagon ecosystem, the first question they asked was: what kind of support can be obtained from Qualcomm. This question is very reasonable, because other companies that do not have a sincerity company, engage in ecological cooperation projects, just put a logo or text chain on the official website, there will be no deeper content.
First, as a developer under the Qualcomm ecosystem, you get the Hexagon SDK, which includes a DSP library, an API, a sample application, a Hexagon simulator, and a wealth of documentation and reference material. These materials can help you optimize your application for DSP. Qualcomm's own engineers will also spend time with developers on customizing time to better integrate with mobile devices. The hardware ecosystem created by Qualcomm also provides a set of development boards that allow developers to test custom effects on the hardware before the actual integration is complete.
But the biggest potential for developers in the ecosystem is to reduce the time required for development. One of the main reasons why differentiation is relatively rare in low-end products is that only a few mobile phone manufacturers can afford the progress problems of integrating developers' customization into mobile phones, and they usually can't afford to develop their own customization. One-off engineering investment. With the dynamic loading object technology provided by the Hexagon SDK, developers and mobile phone manufacturers can join the custom functions of the DSP at any time, even after the phone is shipped.
The SDK has been lubricated between developers and handset manufacturers, and integration work that previously took months to complete may now take only a few days or weeks. Integrating 24-bit/192KHz music playback or computer vision into high-end or low-end devices is no longer as complicated as brain surgery.
For example, before Qualcomm releases the SDK, developers will use Qualcomm's source code to customize a high-end audio decoder for Hexagon, which will take six to eight months (Qualcomm will also spend a lot of time supporting your development). This feature can be integrated into the new device of the manufacturer. Developers who use the Hexagon SDK in the future will only need a few weeks to migrate, integrate and test, and almost no Qualcomm support.
