volumes of digital processing are very large, in order to increase the speed, commands and data spaces are separated to access two spaces using two buses. At the same time, generally, there is high-speed RAM in the DSP. Data and programs must be loaded to the high-speed slice Ram before they can run. To improve the efficiency of digital computing, DSP sacrifices the convenience of memory management and has many poor support for multiple tasks. Therefore, DSP is not suitable for multi-task contr

FPGA is short for field programmable gate array (Field Programmable Gate Array). It is a product of further development on the basis of PAL, gal, PLD, and other programmable devices, is the most integrated type in specialized Integrated Circuits (ASIC. Xillnx, an American company that launched the world's first FPGA chip in 1985. During the past two decades, the hardware architecture and software developmen

1 SRAM Read-Write timing interpretation Memory is overwhelming, and is the size of the computer system (including embedded systems) is not a small part. It is no exaggeration to say that there must be a data transfer process where there is memory, whether it is embedded in the CPU or plug-in, in the code store or program running when it must be necessary. In this section, the experimental object SRAM (Static RAM) is an asynchronous transmission of volatile memory, its read and write transmissio

Any hardware engineer is familiar with FPGA, just like C language is a required course for software engineers. As long as it is an electronic-related student, you must learn the programmable logic course. The full name of FPGA is field programmable gate array, a field programmable gate array, which is a product of further development on the basis of PAL, gal, EPLD and other programmable devices. From the ap

FPGA low temperature cannot start analysisPhenomenon Description: In the medium plate light end machine to do low-temperature test, respectively to the transmission version, the receiving board power-off restart, found that some boards in the -40° can start, and some boards in -20° are not able to start, need to raise the temperature to 0° above to start, The observed phenomenon is that the 4 LED lights that indicate the status are lit, and the

The FPGA design human body consists of six steps: design input, synthesis, functional simulation (pre-simulation), implementation, timing simulation (post-simulation), and configuration download. the design process is shown in step 2. The following describes the design steps. 1. design input The design input includes three methods: Hardware Description Language (HDL), status chart, and schematic input. The HDL design method is a good method for des

In the field of embedded development, arm is a very popular microprocessor with extremely high market coverage. DSP and FPGA are used as co-processors for embedded development, assists the microprocessor to better implement product functions. What are the technical features and differences between the three? The following is a summary of this issue.Arm is a well-known enterprise in the microprocessor industry. It has designed a large number of high-pe

Of course, this is only my opinion, because it seems that many people in the same major do not talk about FPGA application systems, I have always insisted that it is just as wasteful as using P4 CPU to make digital TVs.

, the conversation with a predecessor let me once again determined the technical path to the end of the determination and courage. "After all these years you have gone right, you have no detours ... In any case, technology cannot be lost. " It is also a coincidence that I know the elder. (all sorts of titles pass by), now he is not worried about the "free technical professional", he pursues not what success, is the free pursuit of technology. And in turn,I also talked to a friend in HW years, hi

FPGA supports multiple configuration/loading methods. It can be roughly divided into two types: active and passive. Active loading refers to the configuration process controlled by FPGA, and passive loading refers to FPGA only passively receiving configuration data. The most common passive configuration mode is to download bit files using JTAG. In this mode, the
