The riscv-gcc tool includes some built-in macro parameters. We can use these built-in macros to determine the behavior of the compiler. 1. Viewing GCC Built-in Macro Parameters Here, we take the riscv-nuclei-elf-gcc toolchain released by Chipone Technology as an example. Using the following command, we can get the built-in macro parameters of this tool: riscv-nuclei-elf-gcc … Read more
Basic Working Principle of ADC Source: CSDN Blogger:xtmtm ADC ( analog to digital converter ) conversion process The basic conversion principle of ADC is divided into four processes: ① Anti-aliasing filter ( Anti-aliasing ), which can be understood as a low-pass filter ② Sample and hold circuit ( Sample and hold ) ③ Quantization ( … Read more
The Fourth Industrial Revolution, driven by technologies such as the Internet of Things, big data, robotics, and artificial intelligence, is sweeping across the globe at an unprecedented pace. As a fundamental aspect of these technologies, digital signal processing has become essential knowledge for relevant technical personnel. The digital signal processing course serves as a major … Read more
1 Introduction In the process of information signal processing, filters are used for tasks such as signal filtering, detection, and prediction. Digital filters are the most widely used devices in digital signal processing (DSP). The commonly used filters are Infinite Impulse Response (IIR) filters and Finite Impulse Response (FIR) filters. Among them, FIR filters can … Read more
The Kia Sportage performs satisfactorily, with a simple and mature interior, making it a good family car. However, the owner enjoys listening to music and has strict requirements for the sound system, which the factory-installed audio clearly cannot meet. The original sound system in the Sportage uses six speakers, but due to the rough craftsmanship … Read more
With the stagnation of Moore’s Law and system-level enterprises beginning to attempt to create their own chips, EDA and IP vendors seem to know that their spring has arrived—because their customer base has expanded. However, for EDA/IP vendors, there remains a massive obstacle in front of them: the complexity and high threshold of chip design … Read more
Abstract: In order to verify the overcurrent protection and short-circuit protection functions of the circuit breaker and accurately grasp its working state, a set of circuit breaker calibration device based on DSP and the latest control technology of power electronics is developed. The DSP was used to calculate the test parameters and control the SPWM. … Read more
Introduction:The stratospheric airship sensor data measurement device is used to collect the pressure difference inside and outside the airship’s envelope, the atmospheric pressure of the environment where the airship is located, and the voltage of the power supply battery. The processed data is packaged and sent to the flight control computer, providing key parameters for … Read more
Abstract: Aiming at the current situation of the electronic control system of medium and small power AC mine hoists, a dual PWM frequency conversion speed regulation system based on DSP is proposed. This article elaborates on the hardware and software design of the system in detail, designing the main hardware circuits and part of the … Read more
During the missile development process, to assess its anti-jamming performance, an infrared jamming source deployment device needs to be installed on the target aircraft. Within a specific time frame after the target aircraft takes off, infrared jamming munitions are deployed according to a certain sequence, creating an infrared radiation source around the target aircraft that … Read more
