General Lee: For such a TSP platform, indeed, is the test of the ability to integrate the same time, just She always has been mentioned in the business platform is a completely independent intellectual property platform and our platform is t In the shape of the design, the Core wing broke through the traditional appearance of the other models, the Core-wing sense of movement and high-level sense of the high degree of balance, which must be improved, both in the interior styling
The dual-core CPU in the automotive electronic systems made rapid application system software and hardware, power consumption and heat dissipation also need to follow to make corresponding changes.Car, most microcontrollers today are basically using the traditional single-core structure, but has been widely used in the dual-core processor in the computer industry achieved rapid development in the automotive industry, and soon became the standard configuration. Power systems and security systems have been the first to adopt the dual-core processors, and other systems are also beginning the transformation of the architecture."Multi-core power of the new generation of product design standards," said GM's electronic integration and software director KentHelfrich. "In the past decade, we in the engine control module, a number of multi-core design we are now integrating these design into a chip."However, the application of multi-core processors in some systems, such as infotainment systems is still relatively limited, but rapid growth is expected in the coming years. The chip maker is expected to be of great change in product mix.As with most electronic design, software is the biggest challenge faced by the electronic control designers. To recognize the dual-core processors to enhance the speed, it is necessary to separate Both single-and dual-core processor a clear commitment to the task.Most of the chip maker, said dual-core processor speed is about 1.7 times the single-core, but because the memory access and other issues will slightly affect the speed of the dual-core, so the clock rate of the two processors are very similar. But segmented bad program also affect the performance of the processor."If segments of the program did not do well, it is hard to enjoy the performance advantages, it very difficult to car camera and backup camera achieve performance improvement targets," said STMicroelectronics company automotive microcontroller market manager JulienFabregues.In automotive applications, OEMs and Tier 1 suppliers are doing the segment code, rather than relying on the operating system or other software tools. This is particularly important for some systems, such as power systems and security systems, because the instruction in these systems must be accurate when there is a demand to start."Now, we have to put part of the code points to 0 processor, part of the points to a kernel which there is a conversion problem," Helfrich said. General technical staff MichaelGrimes pointed out that in this way (referred to as static allocation) to form a fixed pattern. The field of computer operating system uses dynamic allocation, the system determines which kernel to run the code, "he said. "And we decide 0 kernel what to do, a kernel and doIt is worth mentioning is that the downstream market applications are enticing, but the industry as a whole is not able to sit back and relax. Upstream data, access to information, the current limit is more stringent, if companies can get more data more secure and convenient way, the entire industry will be rapid growth. Indeed, there is a lot of innovation in every aspect of the map information industry chain, if the Government can provide more special support fund to support these innovations, we will undoubtedly do a better job.
