The development of recording products has a history of over a decade since 2000. Currently, there are generally two common architectures for recording hosts on the market: PC architecture and embedded architecture. How to choose the right recording system? Let’s first understand the differences between the two. Appearance Comparison Embedded Architecture The embedded architecture recording … Read more
CIP (Core Independent Peripheral, independent of the core peripherals) functionality has been discussed in previous articles. CIP can alleviate some of the workload of the interrupt system, but it cannot completely replace it. Both have their own advantages and disadvantages in terms of operational characteristics, and this article provides an analysis of their pros and … Read more
Bluetooth Low Energy (BLE), as an important component of Bluetooth technology, plays a crucial role in device discovery, connection establishment, and data transmission through its Link Layer. Among its core functions, Device Filtering is designed to optimize resource consumption during scanning and connection processes, improve communication efficiency, and reduce unnecessary interactions. This article will delve … Read more
Have you ever heard the advice: to save battery, you must turn off Wi-Fi and Bluetooth when your iPhone is not in use? 🔋 Is this somewhat unreliable “battery-saving tip” true, or are we just wasting our efforts? Today, we will explore this common question. 🤔 For a long time, we have habitually believed that … Read more
In embedded systems, the clock is the “pulse” of the microcontroller (MCU) — every data transfer, instruction execution, and peripheral operation relies on the precise synchronization of clock signals. The “clock tree” is an intelligent system that manages these “pulses”; it resembles a large tree with distinct branches, starting from the root of the original … Read more
Recently, Arm held the Arm UNLOCKED summit in Shanghai, officially launching the Arm Lumex Compute Subsystem (CSS) aimed at mobile devices. What is Lumex CSS? In the simplest terms, it is essentially a “marketing concept” from Arm. Lumex CSS includes at least Arm’s brand new C1 series CPU architecture design, G1 series GPU architecture design, … Read more
In the wave of upgrades for smart locks, Bluetooth (BLE) has become an indispensable connection method due to its low power consumption, high popularity, and ease of use. An excellent Bluetooth module can ensure stable operation, long battery life, and a smooth user experience for the lock. However, with a plethora of modules available in … Read more
Following NVIDIA’s announcement at the end of August regarding the Rubin architecture chip set to enter mass production next year, NVIDIA discussed the progress of Rubin at the Goldman Sachs Technology Conference on September 8. NVIDIA’s Chief Financial Officer, Colette Kress, stated that the Rubin chip is already preparing for market entry,and the Rubin architecture … Read more
I recently tested the operating power consumption of an M0+ MCU. The test code used the simplest method, which is to run an empty loop while(1) in the main function. The measured current was 1.11mA, using the KEIL MDK IDE with optimization level 0. When I inserted 3 NOP instructions before the while(1), the measured … Read more
Beijing ZettaSensing Technology Co., Ltd. has recently announced the official launch of its new high-sensitivity MEMS strain sensor chip – ZSFS1001. The release of this product embodies ZettaSensing’s core philosophy of “chip as sensor,” achieving a high level of integration of MEMS and ASIC technologies on a single chip, providing a new technological path for … Read more
