Living in the multimedia age

Once upon a time, the embedded system we were impressed with was a dedicated computer system that was part of the device or device. In fact, all devices with digital interfaces, such as watches, microwave ovens, video recorders, and automobiles, use embedded systems. Only then, embedded systems seem to be far from multimedia applications and multimedia human-computer interaction.

The footsteps of technology always allow us to see applications that were previously unimaginable. Today, we are already living in the multimedia age. The multimedia application of embedded products allows people to enjoy the beauty of technology, and intelligent multimedia is everywhere. In intelligent transportation, network camera on the road for vehicle navigation, flow control, information monitoring; in terms of car service, GPS allows you to adjust the driving route in time to enjoy smooth travel; in the smart home, the network of refrigerators, air conditioners, etc. Intelligentization will lead people's lives into a new space. Even if you are not at home, you can remotely control via a network via wireless communication devices such as mobile phones and tablets. Do you want to interconnect and share video resources between TVs, tablets or other handheld devices? I believe you have had a experience; if you are shopping outside, your mobile phone can be a remote orderer, helping you in advance. Prepare food; in the home intelligent management system, remote automatic meter reading of water, electricity and gas meters, safety fire prevention, anti-theft, special control chip can replace traditional manual inspection, and achieve higher accuracy and safer performance. In terms of life, I believe that web cameras, video surveillance, video telephony, and mobile TV can be seen everywhere, bringing us a convenient, safe and comfortable life... We have become more and more dependent on video human-computer interaction.

Achieving perfect and secure video processing and human-computer interaction requires strong support from electronic technologies, such as MCU control and management capabilities, such as the content processing capabilities of multimedia application processors.

Feike Semiconductor has a comprehensive range of MCU and multimedia processor products that provide robust support for a wide range of embedded products for secure and reliable human-machine video interaction.

The importance of MCU in human-computer interaction

Want to make the machine interaction unable to work or lose control? Then give up the MCU. Of course, we can't really do this, and the safe, efficient, low-power MCU is exactly what we are pursuing. Since the human-computer interaction terminal usually does not always remain connected to the charging power source, the MCU's power consumption control of the system is particularly important. Not only the power consumption of the MCU itself needs to be controlled, but the correct selection of the MCU also makes the energy consumption of the entire system reasonably used, thereby extending the use time. At this point, Freescale's MCU has solved the worries for design engineers.

Complete MCU products offer more choices

Freescale's comprehensive line of 8-, 16-, and 32-bit MCUs is used in a wide range of industries including industrial, networking, energy, automotive, medical, and consumer electronics. These MCUs offer a wide range of solutions for human-computer interaction and wireless communication management.

For example, in smart home applications, Freescale is constantly adding MCU products and solutions that are available to meet real-world needs, and has accumulated a lot of experience in this field. With these advanced product lines, Freescale offers smarter and more cost-effective solutions for lighting, HVAC, network control, building access, surveillance and security, and home smart energy. These solutions can meet the market's needs in terms of environment, energy efficiency, and reliability.

The Kinetis E series is one of the choices for smart home applications. The Kinetis E-Series 32-bit MCUs are highly scalable ARM Cortex-M0+ core MCUs that are gaining market acclaim for their low power consumption. Kinetis E series has powerful system electromagnetic noise immunity (in the past only 8-bit and 16-bit MCUs have the same level of ability), is white goods (such as dishwashers, refrigerators), industrial applications, home and building control systems, motor control Ideal for fans, industrial converters, and other applications that typically operate in noisy environments. The Kinetis E Series is available in a wide range of memory, peripherals and product packages. They have universal peripherals and pin counts, making it easy for developers to migrate between the same MCU family or multiple MCU families to take advantage of more memory or feature integration. This scalability enables developers to standardize their end product platforms on the Kinetis E-Series, maximizing hardware and software reuse and reducing time to market.

The Kinetis E Series Power Management Module (PMC) offers three power modes: Run, Standby, and Stop modes that operate with energy efficiency. Built-in watchdog and programmable CRC module, 64-bit unique identification number (ID) per chip for greater security.

Kinetis L series devices are also Freescale's unique MCU products, and their low power consumption and excellent energy efficiency also provide perfect human-computer interaction control and management. With this series of MCUs, even in applications with very demanding power requirements, designers are not limited to power consumption limitations and can only use 8-bit and 16-bit MCUs. Kinetis L offers a variety of flexible ultra-low power modes for different applications to maximize battery life, while its energy-efficient architecture utilizes multiple technologies to optimize power consumption, including 90nm thin film memory (TFS) technology, clocks and power supplies. Gating technology and an efficient platform with Bit Processing Engine (BME), Peripheral Crossbar (Crossbar) and Zero Waiting Flash Controller. In addition, energy-efficient peripherals enable intelligent peripheral functions in Deep-Sleep mode to intelligently make decisions and process data without waking up the core. At the same time, the series offers optimized dynamic and stop currents and excellent processing performance, as well as a wide range of on-chip flash density and a wide selection of analog modules, connectivity and HMI peripherals.

For example, because of the ultra-low power consumption, high efficiency, compatibility, display and RF support, Freescale Kinetis L series can prevent tampering and low price, making it a four-meter including flow meter. Ideal for applications.
