Resolve MTK6516 CPU Problems

MTK6516 CPUProblem solving is the content to be introduced in this article, mainly to understand and learnMTK6516MediumCOUProblems and Solutions. For details about the implementation, see this article.

Question 1: Why is the arm926ej-s displayed in the CPU Column

Recently, everyone seems to be very entangled in the android test CPU. Although I think this problem is actually very idiotic, it is a problem not to say that I can run Android 2.2 for 1.6 CPUs, I will not talk much about the more profound terms. I think it should be as concise as possible. First, the software for Android is written in C language. Actually, it is similar to the software algorithm used to test the computer CPU.

The first step through the language to test the CPU system framework that we see the arm926ej-s, in fact, this framework is useful in many large factories, such as Samsung/Qualcomm part of the CPU is based on this design) the second step, according to the above framework to narrow the scope, in the database itself to find the CPU information, No, it directly shows the Framework, so we saw the arm926ej-s.

Question 2: Why does the CPU display only 208 frequency?

The MTK6516 chip is composed of two chips, ARM9416MHz and ARM7208MHz. If you say dual-core, the true dual-core is absolutely tearful. What does MTK start from, the high integration reduces the production cost of mobile phones. MTK6516 is not a CPU, but a chipset.

For example, it is a host without a chassis. ARM7208 is the control chip of the entire motherboard and is responsible for some features such as hard decoding RMVB. The real system operation is the one of ARM9416, the display is due to the startup sequence of MTK6516, and the software stops when it detects that it is operating the CPU, because currently there are few such mobile phone packages.

Question 3: What is the actual limit of MTK6516?

According to the design of arm926ej-s, of courseMTK6516There are a lot of public and non-public versions. This can only be a concept. I used to talk with my classmates. At the time of design, MTK6516 should be able to reach a good level, but it is caused by the yield rate problem, so the lock is locked, and the lock is a hard lock. If you want to exceed the lock, you can save the trouble. As for the case, do not worry too much about the testing of the software or the CPU comparison of Android, people's testing software has been relatively optimized based on the well-known manufacturer's CPU. What is MTK? Shanzhai, And the MTK6516 is indeed awesome. At least it is relatively stable, isn't it? If performance is required, this chip is enough.

Reply to some people's questions

In fact, I just want to explain the truth. Is it necessary to care about this CPU information so much? If it is 208, can it pull 2.2? And dude, 6516 is also an old chip, but it's special. If you really want to use a computer, I really have no idea. The software cannot mistakenly test the modem at ordinary times. The problem is the MT6516 startup mechanism. ARM7208 is not only the MODEM, but also the MTK integrates the BOIS of the entire MTK6516, so I just mentioned why.

Of course, you said that 208 is arm9-can also, because MTK6516 is based on the arm926ej-s design, arm926ej-s framework including mobile phone/motherboard/CPU can be, just like the dual data rate principle in the DDR test, it shows that the working frequency is 208 and the actual frequency is 416. However, it is estimated that it is only understandable, do you think this is necessary? In fact, just like the year ATOM, just out of the time also because of relatively new, the original frequency is actually 1.4G indeed show 700 M, the problem is that people are intel out of something, CPU-Z will immediately correct, do you think this test software will modify the database because of MTK?
