The LHDC-V version of the high-definition Bluetooth protocol standard has been released, supporting up to 24bit / 192KHz. According to officials, the LHDC-V version achieves true 24bit/192Khz transmission within the effective code rate range under the classic Bluetooth audio transmission and LE Audio architecture. The frequency response range reaches 20Hz – 96KHz. Due to the increased bit and sampling rate, it can have Compared with CD sound quality, it has a larger dynamic range and can more truly restore the details of music.
According to officials, LHDC brings high-quality sound and immersive experience upgrades to driving by supporting vehicle computers and optimizing and adjusting vehicle indoor space parameters. Drivers and passengers only need to use Mobile phones equipped with LHDC (all Xiaomi series, OPPO mobile phones, etc.) can connect to the car via high-definition Bluetooth and quickly enjoy a Hi-Res level flagship experience.
According to Taiwan’s Business Times, the core design of Apple’s new M3 SoC has been launched and will be released as early as the second half of 2023. Apple's M3 chip is internally codenamed "Malma" and will be mass-produced on TSMC's N3E architecture. N3E is said to be an improved variant of the N3 process, also 3nm. N3 offers up to 15% performance improvement and up to 30% energy efficiency improvement compared to N5, and N3E will further expand these differences.
The report states that, optimistically, the M3 chip may be launched in the second half of 2023 or the first quarter of 2024. Next year we will see Apple's first batch of 3nm chips, and as mass production begins, Apple will also import them into the A17 Bionic chip used in the iPhone 15 Pro / Pro Max.
The latest data released by IC Insights, a well-known semiconductor analysis organization, shows that the three years from 2020 to 2022 will be the first three-year period in which capital expenditures have achieved double-digit growth since 1993-1995. IC Insights has adjusted its 2022 global semiconductor capital spending forecast to now show growth of 21% this year to $185.5 billion.
It is now expected that semiconductor capital expenditures in 2021 and 2022 will total US$338.6 billion. IDMs and foundries are investing heavily in capacity expansion to manufacture logic and memory devices using leading process technologies. However, strong demand and continued shortages of many other important chips, such as power semiconductors, analog ICs, and various MCUs, have led suppliers to increase manufacturing capabilities for these products as well.
Apple was granted a second patent for their AR-based “measurement” app. This week, the U.S. Patent and Trademark Office published two patents (01 and 02) covering Apple’s AR “measurement” app. The patents measure a user’s wrist size in a new way so that those purchasing an Apple Watch online can Better determine what strap size they should buy.
The U.S. Patent and Trademark Office published Apple’s third patent focusing on “measurement” last Thursday, showing that the company has more research underway, including using smart ring devices to control HMDs. .
