processor I/O pins, we must take into account certain pins that are restricted when using the internal functions of the processor, such as serial interfaces and timers.2.2. Number of interfaces to be usedThe main function of the embedded processor is to interoperate with the hardware in the application environment, which not only requires the external hardware to have real-time processing capability to the interface, but also requires the processor to efficiently handle the interface data at a

important thing is not to accurately calculate the code length of a program, but to clearly estimate the upper limit of the code length. According to experience, if 80% of the RoM space is occupied by code, it will be too crowded unless it can ensure that the system requirements will not change, otherwise, at least reserve enough spare Rom space for possible changes.In most cases, we can try to write some program code in the Rom to observe the space occupied by the Code. For a

hardware closely related to embedded applications is retained to remove other redundant functional components, so as to achieve the special requirements of embedded applications with the lowest power consumption and resources. MPU-based embedded systems include digital thermometers. Embedded Microcontroller MCUIn addition to the most basic computing power, a single-chip large-scale integrated circuit also integrates Ram, ROM/EPROM, bus, bus series, A/D, D/A, etc, A typical example is a single-c

storage, as shown in 1. The central processor first reads the content of the program instruction in the program instruction memory, decodes the content, obtains the data address, reads the data in the corresponding data storage, and performs the next operation (usually execution ). The program instruction storage and data storage are separated, which can make the instruction and data have different data widths. For example, the program instruction of the pic16 chip of microchip is 14-Bit Width,

First, let's talk about the development of arm. It can be described as a good one to open the websites of various companies, and embedded recruitment occupies most of the positions of engineers.In the broad sense, there are only a few types of embedded systems: Traditional 51, AVR, and PIC are called embedded microcontroller; arm is an embedded microprocessor; DSP; FPGA.Objectively speaking,

Application of Real-time Operating System in Radar Signal Processing [Date:] Source: EDN Author: [Font:Large Medium Small] 　 With the improvement of DSP (Digital Signal Processor) performance and the expansion of application scope, especially in consumer electronic products, DSP not only continues to assume the core role of traditional algorithm processing, some controlling or transacti

for physical test points on the board, which significantly saves costs, because the circuit board layout is simpler, the test fixture is cheaper, the test system in the circuit takes less time, the use of standard interfaces increases, and the time to market is faster. In addition to circuit board testing, boundary scan allows programming almost all types of CPLD and flash memory on the Board after a PCB patch, regardless of the size or encapsulation type. In system programming, you can save co
