Facebook has been in fierce competition with Google in digital advertising. Before launching its own DSP product, Facebook already had the ad server “Atlas”, the SSP platform “LiveRail”, and the ad network “Audience Network”. To observers, Facebook’s launch of its own DSP seemed like a natural progression, given its powerful audience targeting capabilities and experience, … Read more
With the growing global demand for clean energy, photovoltaic inverters, as the core component of solar power generation systems, directly affect the power generation capacity and stability of the entire system. Digital Signal Processors (DSPs) are widely used in photovoltaic inverters to implement complex control algorithms, enhancing the system’s response speed and accuracy. This article … Read more
The DSP amplifier is the soul and backbone of a complete audio system. A DSP amplifier refers to an amplifier that uses a DSP chip, allowing for tuning via a computer. Each channel’s parameters (such as EQ, delay, crossover points, etc.) can be better managed through a computer. A complete audio system includes: Head unit … Read more

Introduction: Fixed-point is a great thing, but the coding can be a bit challenging. However, after finding some methods for fixed-point programming, we can still understand, master, and apply it. After all, floating-point microcontrollers are expensive, while fixed-point microcontrollers are quite affordable. The author’s first microcontroller supported floating-point, and the coding mindset has always been … Read more
Today, we continue our work on fixed-point programming, which is quite significant for using PR control, especially since floating-point microcontrollers are expensive. Previously, in floating-point development, we discussed the discretization and code implementation of the Proportional Resonant Controller (QPR). For fixed-point implementation: Considering quantization errors, we directly run the IIR2 function of the PR controller … Read more
