After several years of hard work, MediaTek has rapidly emerged, and its technology, chip and platform solutions are becoming more and more complete. In the field of smart phones, its products are highly favored by mobile phone manufacturers. However, whenever you mention MediaTek, you will always associate it with the thousand yuan machine in your mind. Since then, MediaTek has been working hard to build high-end processors, but it has always been used to create high-end processors. On the "low-end machine", the low end seems to be a nightmare that lingers on the top of MediaTek.
In 2013, MediaTek launched the world's first CorePilot heterogeneous computing technology. CorePilot is a new technology tailored by MediaTek for its multi-core products. CorePilot heterogeneous computing technology can be simply regarded as ARM Big.LITTLE, which is a big core. + Small core architecture technology, has now evolved to version 3.0, not only can support large and small nuclear heterogeneous computing, but also flexible control of the co-work between CPU and GPU, using different intelligent deployment scenarios, so that they can play optimally Performance and optimal power consumption make the terminal products using MediaTek chips more energy efficient.
MediaTek's first CorePilot heterogeneous computing technology
MediaTek CTO Zhou Yujun once said: "Now the impact of mobile phone experience is not the performance of the mobile phone processor, but the battery life, our CorePilot technology can assign different tasks for different core processing, which allows power consumption and performance to get a perfect unity"
For example, when a smartphone runs a streaming application, it needs to occupy the CPU resources, and the corresponding display is needed on the screen, so it will occupy the resources of the screen, and also consume the resources of the multimedia module in the processor, if this stream When the media comes from the network, you need to use the resources of the modem. In the above process, the circuit used will affect the heat, and for the user, the experience is a result of all the above processes. In this process, CorePilot technology adjusts the processor so that different modules are made. The corresponding changes, so that the mobile phone experience is better, the user feels the best.
CorePilot 1.0: Reasonable call to the CPU core
In July 2013, MediaTek launched the first mobile processing chip with CorePilot heterogeneous computing technology, the MT8135, for Android tablets, which maximizes performance and reduces power consumption when used.

CorePilot 1.0 is designed for load balancing and better performance for efficient management of symmetric and asymmetric multicore CPUs. Because of the different smart deployment scenarios, they can achieve optimal performance and optimal power consumption. Compared with the previous, the daily use tasks can reduce power consumption by 70%, making the terminal products using MTK chips more energy-efficient.
CorePilot 1.0 includes three technologies. First, the latest heterogeneous scheduling algorithm can more effectively balance the workload of each CPU core to improve system efficiency. Second, the self-adjusting temperature control technology can turn the CPU core on or off according to the temperature change, and dynamically adjust the power consumption budget within a certain range to obtain better performance improvement. Third, the dynamic power management technology can detect the ongoing process and task load through the dynamic voltage and frequency adjustment module, thereby automatically adjusting the frequency and voltage of the CPU, and finally decides to turn on or off some CPU cores, so as to Effectively reduce the heat and energy consumption of the idle CPU core.
