The Future Development Trend of Embedded Systems
Oct 12, 2018

In the information age, the digital age has made huge opportunities for embedded products, showing a bright future for the embedded market, and also posing new challenges for embedded manufacturers. From this we can see how many embedded systems will be in the future. Big development trend:

1. Embedded development is a system engineering, so embedded system vendors are required to provide not only the embedded hardware and software systems themselves, but also powerful hardware development tools and software packages.

At present, many manufacturers have fully considered this point. At the same time as the main push system, the development environment is also promoted as a key point. For example, Samsung promotes Arm7, Arm9 chip also provides development board and version and support package (BSP), while WindowCE also provides Embedded VC++ as a development tool in the main push system, as well as Vxworks' Tonado development environment, DeltaOS's Limda compilation environment. Etc. are typical examples of this trend. Of course, this is also the result of market competition.

2. The requirements of network and informationization With the maturity of Internet technology and the increasing bandwidth, the functions of previously single-function devices such as telephones, mobile phones, refrigerators, microwave ovens are no longer single, and the structure is more complicated.

This requires chip designers to integrate more functions on the chip. In order to meet the application function upgrade, designers use a more powerful embedded processor such as 32-bit, 64-bit RISC chip or signal processor DSP to enhance processing. Capabilities, while adding functional interfaces such as USB, expansion bus types, such as CAN BUS, to enhance the processing of multimedia, graphics, etc., and gradually implement the concept of system-on-a-chip (SOC). Software uses real-time multitasking programming and cross-development tools to control functional complexity, simplify application design, ensure software quality, and shorten development cycles. Such as HP

3. Internet interconnection has become an inevitable trend.

In order to adapt to the requirements of network development, future embedded devices must require various network communication interfaces on the hardware. Traditional single-chip microcomputers lack network support, and a new generation of embedded processors have begun to embed network interfaces. In addition to supporting TCP/IP protocols, some support IEEE1394, USB, CAN, Bluetooth or IrDA communication interfaces or Several kinds of communication networking software and physical layer driver software are also required. The software system system kernel supports the network module, and even the Web browser can be embedded in the device, realizing the use of various devices to access the Internet anytime and anywhere.

4. Streamline system cores, algorithms, and reduce power and hardware and software costs.

Future embedded products are devices that combine hardware and software. In order to reduce power consumption and cost, designers need to streamline the system kernel as much as possible, retain only the hardware and software closely related to the system functions, and use the lowest resources to achieve the most appropriate functions. The designer is required to select the best programming model and continuously improve the algorithm to optimize compiler performance. Therefore, software personnel must have a wealth of hardware knowledge, but also need to develop advanced embedded software technologies, such as Java, Web and WAP.

5. Provide a friendly multimedia man-machine interface

Embedded devices can be intimately contacted by users, the most important factor being that it provides a very user-friendly interface. The image interface and flexible control method make people feel that the embedded device is like a familiar old friend. This requirement makes embedded software designers painstakingly work on graphical interfaces and multimedia technologies. Handwritten text input, voice dial-up Internet access, e-mail and color graphics, and images all give users a feeling of freedom. At present, some advanced PDAs have realized Chinese character writing and short message voice release on the display screen, but the general embedded equipment has a long way to go from this requirement.
