WTM2101- The computing in memory structure for Intercom Solution


Intercoms have been widely used as simple yet effective communication tools in various industries. However, as technology continues to advance, the demand for enhanced functionalities in Intercoms is gradually increasing. To meet the diverse needs of users, the introduction of computing in memory technology has brought about new application prospects for intercoms. This article will focus on introducing how the WTM2101 chip based on the computing in memory architecture is applied to intercoms, enhancing communication efficiency and enabling versatile features.

· Data Storage and Retrieval:

computing in memory technology enables Intercoms to efficiently store and retrieve a large amount of communication data. With improved storage capabilities, users can store more call records, contact information, and other relevant data for easy retrieval and review. At the same time,computing in memory technology also enables faster data read and write speeds, enhancing data transmission efficiency.

· Advanced Voice Processing:

With the computing in memory, Intercoms can achieve advanced voice processing capabilities. For example, voice recognition technology can accurately identify command words, allowing for noise reduction, anti-howling, noise suppression, and dynamic range control (DRC) in harsh environments. These features ensure clear and high-quality voice communication, even in noisy or challenging conditions.

The function for Intercom solution is below points:

· Telephone Noise Cancellation: Intelligent Fusion Noise Cancellation (Dual-Mic BF + AI-ENC Noise Cancellation)

· Multiple Howling Suppression: traditional algorithm + NN algorithm

· AEC echo cancellation: duplex intercom

· Local multi-key words control: low-power recognition of more than 100 command words

· Anti-wind noise reduction

· DRC: Dynamic adjustment of audio output amplitude

· Bursting sound suppression
