Source | Embedded Miscellany Today, I will share some commonly applicable skills for advanced embedded software development. Embedded Performance Optimization Cheng Kefe in “Embedded System Design” points out that system-level optimization is key to enhancing the competitiveness of embedded software, which should be approached from three dimensions: code efficiency, resource utilization, and real-time performance. Embedded … Read more
ver0.2 Introduction In previous articles, we introduced the services of the SCP and the working model of the SCP. From the perspective of SCP, all controlled objects are Agents, and the means of controlling each Agent mainly involves voltage, clock, etc., configured through the PPU. In this article, we will spend some time discussing the … Read more
Abstract / This article reviews the power supply requirements for FPGAs, emphasizing voltage accuracy, transient response, and voltage sequencing, and details various challenges related to thermal management through operational examples. It then introduces integrated DC/DC regulators from Analog Devices and evaluation boards and integrated recommendations that can accelerate the design process. These regulators are suitable … Read more
1. Definition and Classification of Power Management ICs (PMIC) 1. Core Functions PMICs are analog chips, serving as the “power heart” of electronic devices, responsible for the conversion (such as AC/DC, DC/DC), distribution, detection, and control, which directly affects device performance and reliability. Typical applications include: Voltage Conversion: Converting battery voltage (e.g., 3.7V) to lower … Read more
In the previous article, we introduced the driver code generated by the VS KMDF template, providing a preliminary understanding of the driver code. It should be evident that this driver is quite simple, essentially lacking any real functionality. After installing the driver we wrote, this PCIe device remains in the D0 state (if you are … Read more
Recently, ACROVIEW, a leader in the chip programming field, launched a significant version update of its programming software. Coinciding with the release of the new version, the company announced the addition of several compatible chip models, including the RTQ6752GQWT programmable power management chip developed by RICHTEK. This chip has successfully completed technical adaptation with ACROVIEW’s … Read more
ver0.2 Introduction Happy holidays, everyone! I hope you all stay happy forever, as we are all still kids at heart. In the previous article, we introduced the PCSA system architecture based on SCP as the core, with PCF as the hardware framework and OPSM as the upper management strategy. After gaining a basic understanding of … Read more
The OCP82131 is designed to support TFT-LCD panels with positive/negative drive of at least up to 10 inches (from SFF to MFF, such as tablets). The two outputs are typically connected to the source driver IC. This device uses a single inductor scheme to provide the smallest possible solution size and high efficiency. It features … Read more
Zhang Xiaolong, Cheng Xin, Wang Yong (Anhui Nari Zhongtian Power Electronics Co., Ltd., Hefei, Anhui 230031) Abstract: To address the issues of slow data acquisition speed and poor functionality expansion in existing power data acquisition terminals, a design scheme for a power data acquisition terminal based on the SCM701 is proposed. This scheme uses the … Read more
