Comparison between ARM, 8051, AVR, MSP430, ColdFire, DSP, and FPGA systems

advantages mean that arm has a wider application scope than AVR. Therefore, if "We use AVR in Middle School" is correct, we should use arm in university.We can see that at91m55800a Based on the ARM core of ATMEL includes a lot of AVR peripherals, but still lacks Twi/I2C, variable gain ADC, EEPROM and other useful components. However, there is no doubt that arm's external expansion and peripherals are more powerful than AVR.In terms of operating system and software source code resources, arm has

On the similarities and differences between MCU, ARM and DSP

Still remember when reading, the teacher said that single-chip computer, ARM, DSP has interoperability, are CPU, but listen to the teacher can not understand.How can I understand them and find out their similarities and differences? Let's take a look at my wife's views:Icer, SOC design for arm CPUsLet me say a few words, hoping to say a little thinner.First of all, said CPU, central processing unit, the essence is an integrated circuit, the function i

The difference between DSP and MCU

Before just learning single-chip computer, after certain programming, can realize a lot of different functions, at that time, I feel that single-chip microcomputer is really a powerful. Later came into contact with DSP, found that DSP processing digital in communication, more convenient. So I was curious to ask myself, DSP and microcontroller, what is the differe

How to construct Da Vinci's DSP Server_davinc da Vinci

Texas Instruments (TI) 's Leonardo da Vinci (DaVinci) Digital media technology platform includes four major parts: chips (processors), development tools or development kits, software and technical support. Software development involves the operating system, audio and video codec algorithm and arm and DSP between the division of cooperation, so that many engineers feel more complex. TI introduced a series of software modules and tools to establish the

The bustling and sad DSP

1. What is a DSP?I'm used to understanding any one technology from two angles 1. It solves what problem 2. For whom it serves. For DSP, I think DSP is to solve the problem of the complexity and ROI of the programmatic purchase of advertisers, which is born to advertisers. If the advertising industry is simplified into: media (supply), advertising platform (ADX) a

What DSP should know best

How does one mix 1.5 V/3.3v?The development of TI DSPs is the same as that of Integrated Circuits. The new DSPs are all 3.3v, but many peripheral circuits are still 5 V. Therefore, in the DSP system, there are often 5 V and 3 v dsp mixed connection problems. In these systems, Note: 1) the DSP outputs to a 5 V circuit (such as D/A), which can be directly connected
