Source: | Renesas Embedded Encyclopedia Helium technology, which is the M-profile Vector Extension (MVE) of Arm, is a crucial part of the ARM v8.1M architecture. Currently, the cores under the ARM v8.1M architecture include Cortex®-M52, Cortex®-M55, and Cortex®-M85. For example, last year Renesas released the Cortex-M85 core RA8 series microcontroller. The following table, Arm Cortex-M … Read more
Where does the speed improvement of STM32 come from? That’s right! The component that accelerates the image classification processing speed of STM32 is the Digital Signal Processor (DSP). Currently, Arm‘s Cortex-M4, Cortex-M7, Cortex-M33, and Cortex-M35P microcontroller cores all come with DSP. Compared to CPU (which excels at scheduling), DSP is very good at computations, handling … Read more
A complete audio system cannot be without a professional processor and amplifier. The Finlang DSP8, a monitoring-level professional DSP audio processor, is being installed nationwide. The car owner pursues a sense of sound layering; their exact words were: ‘I feel like all the sound is coming from the left.’ Installing a DSP is just right … Read more
Abstract in Chinese: A highly reliable power management circuit of digital signal processor (DSP) TMS320F28335 is designed. The power supply demands of the DSP were analyzed, and the required power was accounted. The 1.9 V and 3.3 V dual power supply management circuit meeting demands of power and power-on timing of the chip was designed. … Read more
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
