About Computing in Memory

  Introduction to Computing in Memory Computing in memory, also known as in-memory computing or computational memory, is a new paradigm that aims to reduce data movement and increase data processing speed by performing computations directly in memory. In contrast to traditional computing architectures that rely on a separation of memory and processing, computing in memory systems leverage the inherently parallel processing capabilities of memory devices to achieve high-throughput and low-latency data processing. Advantages of Computing in Memory Applications Computing in memory has several advantages over traditional computing architectures. One of the biggest advantages is the reduction of data movement, which significantly reduces power consumption and improves overall efficiency. Additionally, computing in memory enables higher bandwidth data processing, faster data transfer rates, and lower latency. These advantages make computing in memory particularly attractive for applicati...

The role of howling suppression in the WTM2101 chip

图片
  The principle of producing feedback is that when a microphone and a speaker are used simultaneously, the sound signal captured by the microphone is amplified by the speaker and then output again, forming a feedback loop. Due to the existence of the feedback loop, some specific frequencies of the sound signal can become very strong after multiple amplifications, forming a howling noise. The principle of howling suppression is to use digital signal processing technology to monitor the audio input and output signals in real-time, and identify and eliminate signals that may cause howling. Specifically, the howling suppression algorithm will perform frequency analysis on the input and output signals, and when the strength of the signal in a specific frequency range exceeds a certain threshold, it will recognize that there is howling noise. Then, the howling suppression algorithm will use a certain algorithm model to eliminate or reduce the signals that may cause howling, thereby elimi...

How does AI-ENC play an important role in TWS smart earbuds

图片
  With the development of TWS technology and intelligence, TWS smart earbuds will play an important role in wireless connectivity, voice interaction, intelligent noise reduction, health monitoring, and hearing enhancement/protection, not just as standard equipment for smartphones, but even becoming an indispensable part of the human body. Noise reduction, hearing protection, intelligent translation, health monitoring, bone conduction+bone sound pattern, anti-loss, etc. will be the key technologies for TWS earbuds. Among them, noise reduction is the top priority, and the two mainstream active noise reduction modes on the market are ANC and ENC. Active noise reduction is achieved through the collaboration of hardware (chips, sensors, microphone arrays, etc.) and software algorithms. Currently, TWS earbuds mainly have two active noise reduction methods: ANC and ENC.

Based on computing in memory technology, achieved NN VAD and speech recognition

图片
  WTM2101 is a speech recognition and wake-up chip based on computing in-memory technology, with a core consisting of a set of low-power processors specifically designed for speech recognition. Compared to traditional speech processors, WTM2101 adopts a series of optimization measures for speech wake-up and recognition scenarios, significantly reducing power consumption. One of the most important optimization measures is the full phoneme algorithm model. Traditional speech recognition algorithms require a large amount of acoustic and linguistic knowledge to build complex acoustic and language models to achieve high-precision recognition. The full phoneme algorithm model uses a simpler speech unit, namely a single phoneme, to avoid complex acoustic and language modeling, thereby greatly reducing the complexity and power consumption of the algorithm. Offline speech wake-up and recognition technology has been widely used in smart homes and smart speakers. The balance between AI speech...

WTM2101 - Ultra-low Power Implementation of NN Environment Noise Reduction Algorithm, Health Monitoring and Analysis Algorithm

图片
  Currently, most TWS devices use traditional dual or triple microphone ENC-based algorithms for voice enhancement and noise reduction. These algorithms can pick up sound directionally and reduce noise from other directions, but they also have significant drawbacks. Traditional noise reduction algorithms can cause some damage to human speech when directional pickup is achieved through phase manipulation, resulting in a muffled sound. They cannot effectively reduce noise from the same direction as the human voice, and they are not effective in high-noise environments, such as subways, trains, cafes, and roads. NN-based environment noise reduction algorithms are more versatile and can analyze collected audio directly using the characteristics of deep learning to separate human speech from noise, improve signal-to-noise ratio, reduce environmental noise, and preserve human speech. NN environment noise reduction can work alone with a single microphone, without requiring custom tuning a...

Features of computing in memory

  Computing in memory is not a new concept. As early as the 1990s, there were discussions on the prototype of computing in memory, but the development of hardware was limited at that time, and no further research was carried out. There is no unified definition of the concept of computing in memory. GridGrain gives this explanation about memory computing: by using a middleware software, data is stored in memory in a distributed cluster and processed in parallel. Techopedia believes that as memory prices drop sharply and memory capacity increases, it is better to store information in dedicated server memory instead of slower storage disks. It can help business users quickly perform pattern recognition and timely analysis Big data is the so-called computing in memory. Computing in memory is not only about storing data in memory, but also requires special design of software systems and computing models. Therefore, it can be seen that memory computing mainly has...

Solving the "storage wall" problem: opportunities and challenges in the development of computing in memory

  Thanks to the rapid development of the semiconductor industry over the past half century driven by Moore's Law, computing power has been experiencing significant leaps. The integration density of integrated circuits doubles every two years, and then this cycle shortens to 18 months. The performance of microprocessors increases by 1 times every 18 months. However, as the economic cost of silicon chips approaches its physical limit, Moore's Law may become invalid in the future. The processing logic based on the Von Neumann architecture, which is based on the instruction set pattern, requires data to be transmitted back and forth between the processor and memory at runtime, resulting in significant power consumption. Nowadays, the shortcoming of processing massive data, especially irregular massive data, is increasingly evident in high-performance computing environments such as artificial intelligence. Solving the "storage wall" bottleneck has become urgent. In this co...
