The Verdin AM62P utilizes Texas Instruments’ AM62P5 SoC. It is an ideal choice for accelerating graphics applications, featuring a powerful GPU with a theoretical computing power of 50 GFLOPs (more than three times the theoretical performance of the i.MX 8M Plus). This processor is equipped with three display controllers, allowing for up to three display … Read more
MIPI (Mobile Industry Processor Interface) is a mobile device interface standard established by the MIPI Alliance, founded in 2003 by companies such as ARM, Nokia, and TI. Its core goal is to standardize internal interfaces of mobile devices (such as cameras, displays, baseband chips, etc.) to reduce design complexity, enhance flexibility, and address compatibility issues. … Read more

Today, we will discuss a concept in electronics that is often confused: the resolution of an Analog-to-Digital Converter (ADC) and its accuracy. Although these two terms sound similar, they represent vastly different meanings, much like a ruler where fine markings do not guarantee accurate measurements! 1. Resolution of ADC (Resolution): Similar to the smallest scale … Read more
Hello everyone, I am Pi Ge! Have you ever wondered how mobile phone screens display images? How do televisions receive high-definition signals? How does an industrial control screen communicate with the system? The answer lies in various display interface technologies! Common display interfaces, such as LVDS, DSI (MIPI DSI), and HDMI, may seem like mere … Read more
“When testing the Integral Non-Linearity (INL) and Differential Non-Linearity (DNL) of multi-stage DACs, it is usually unnecessary to perform a full test on all codes. Instead, validation can be achieved by carefully selecting a subset of key codes.” For example: a 16-bit 3-stage DAC, which internally contains 3 sub-DACs (7-bit, 5-bit, 4-bit), requires scanning all … Read more
“A 12-bit 104-MS/s SAR ADC in 28nm CMOS for Digitally-Assisted Wireless Transmitters”The calibration method introduced here utilizes low-level capacitors to calibrate high-level capacitors, as the absolute mismatch of high-level capacitors is greater, which in turn has a larger impact on DNL and INL. Calibrating high-level capacitors can effectively improve the dynamic range of the ADC.As … Read more
In mobile devices and embedded systems, the MIPI protocol is a key technology for achieving high-speed data transmission. Today, we will delve into the four important concepts of MIPI-DPHY, MIPI-CPHY, MIPI DSI, and MIPI CSI-2, examining their differences and connections. 1. Layered Architecture of the MIPI Protocol The MIPI protocol adopts a layered architecture, mainly … Read more
