“After user evaluation, the FETMX8MP-C core board can meet the product design requirements in terms of function. At the same time, selecting the core board for product development can greatly reduce the difficulty for users to get started and develop the i.MX 8M Plus processor, and shorten the time to market. time. In addition, the i.MX 8M Plus processor is part of NXP’s long-term supply guarantee program, and its life cycle is as long as 10 to 15 years, which also makes the supply cycle of the FETMX8MP-C core board more than 10 years.
In March 2019, the Ministry of Communications of my country issued JT/T 1178.2, namely, “Regulations on Safety and Technology of Operating Trucks Part 2: Towing Vehicles and Trailers”, which stipulates that from May 1, 2020, newly produced tractors should have Forward Collision Warning (FCW for short) and Lane Departure Warning (LDW for short), both of which can be implemented through the intelligent driving terminal of commercial vehicles. Smart devices with functions included in some advanced driver assistance systems (aka ADAS).
In addition to the mandatory requirements of the national standard to be equipped with FCW and LDW, many commercial vehicles such as construction vehicles and trucks are also equipped with related functions for safety reasons. These applications undoubtedly promote the demand for intelligent driving terminals for commercial vehicles from a market perspective. , lower costs and richer functions have also become the direction of product technology iterations for car manufacturers. With the increasingly powerful performance of embedded ARM architecture processors, intelligent driving terminals for commercial vehicles developed based on the ARM platform have become the choice of more and more car manufacturers and related equipment suppliers.
02 User requirements:
A domestic heavy-duty vehicle factory needs to iterate on the existing X86 architecture commercial vehicle intelligent driving terminal to reduce costs and improve operational stability. In the selection stage of the main control architecture of the device, the user comprehensively evaluates that ARM has more advantages in this application. In the specific processor selection stage, users put forward the following requirements:
1. Dual Gigabit network, connecting webcam and lidar
2. Dual camera
3. Low power consumption, can achieve long-term stable operation
4. 4G/5G network, communicate with the server
5. HDMI interface, external Display for debugging
6. A certain edge computing capability is required to meet the local implementation of some algorithms in ADAS
7. Support CAN-FD to meet the high bus load rate and network congestion pressure caused by the increase of data volume in ADAS
8. At least 5 years supply cycle
9. Solve the pain points of development difficulty and long development cycle when software and hardware engineers develop products based on unfamiliar ARM processors
03The realization of the plan:
According to the selection requirements put forward by users, Feiling Embedded recommends the FETMX8MP-C core board. This core board is based on NXP i.MX 8M Plus processor design, equipped with 4 Cortex-A53 cores with a frequency of up to 1.6GHz and 1 Cortex-M7 core for real-time control, supporting dual Gigabit Ethernet , supports dual MIPI cameras, supports dual USB 3.0, supports 4G/5G communication modules, supports HDMI interface, at the same time, comes with 2 CAN-FD, 1 PCIe 3.0, and the processor integrates a dedicated neural processing engine (NPU ), the computing power is as high as 2.3TOPS, which can meet the local lightweight edge computing. The processor of the FETMX8MP-C core board has a running power consumption of less than 2W, which can be fanless and run stably for a long time.
After user evaluation, the FETMX8MP-C core board can meet the product design requirements in terms of function. At the same time, selecting the core board for product development can greatly reduce the difficulty for users to get started and develop the i.MX 8M Plus processor, and shorten the time to market. time. In addition, the i.MX 8M Plus processor is part of NXP’s long-term supply guarantee program, and its life cycle is as long as 10 to 15 years, which also makes the supply cycle of the FETMX8MP-C core board more than 10 years.
