What is SoC? As the “brain” of fields such as smartphones, automotive electronics, artificial intelligence, and industrial control, SoC (System on Chip) is a highly integrated solution that combines computing cores, storage systems, communication interfaces, and various peripherals into a single chip. The SoC architecture mainly includes four major components:1. Core CORE2. Memory MEM3. Peripheral … Read more
SoC (System on Chip) refers to a system-level chip that integrates key components such asCPU, memory controllers, peripheral interfaces, andAI acceleration units. With advantages of high performance, low power consumption, and miniaturization,SoC is widely used in mobile phones, tablets, and smart home devices. This article takes theMT8519 SoC produced by MediaTek as an example to … Read more
Introduction Recently, I discovered a “treasure”: Microchip’s AN4515 application note, which explains how to run several classic digital signal processing (DSP) algorithms on its AVR® EA 8-bit microcontroller (MCU) along with examples: Figure 1 Microchip AN4515 Application Note, Source [1] This article introduces the basic usage and the first example — the Median Filter. Subsequent … Read more
The ZXB-47DR-8T8R(+DSP) digital array board (mixed signal processing card) is built using a combination of the XCZU47DR and TMS320C6678ACYPA. The XCZU47DR serves as the main controller, enabling 8 transmit and 8 receive signal transmission, acquisition, and control, while providing sufficient peripheral high-speed interfaces as required. The TMS320C6678ACYPA acts as the DSP processing IC, significantly enhancing … Read more

Dot Product Operation and Multiply-Accumulate The dot product operation is a fundamental operation in DSP applications, commonly used in filter and transformation algorithms. The ARM Cortex-M4 provides efficient multiply-accumulate (MAC) instructions for rapid execution of dot product operations. Example Code int32_t dot_product(int32_t *a, int32_t *b, uint32_t length) { int32_t result = 0; for (uint32_t i … Read more
To reduce the output voltage and current ripple of the BUCK converter and minimize the power inductor, using an interleaved parallel BUCK is a good choice. This article briefly discusses the method of driving interleaved BUCKs and closed-loop control based on a digital signal processor (DSP) to provide some insights. The basic topology is as … Read more
Source:ZTE Documentation Original Author:ZTE Documentation This article mainly discusses why listening to music with Bluetooth speakers sounds better. Many people have the feeling that music sounds “better” when played through Bluetooth speakers. From a scientific and technological perspective, this is not an “illusion” but rather a result of the hardware and audio encoding technology of … Read more
