Embodiment 1
[0022] figure 1 It is a flow chart of a global positioning system memory self-adaptive frequency doubling method provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of performing frequency doubling operation on the memory when acquiring satellite information through GPS. The method can be performed by It can be executed by a terminal with frequency multiplication of memory, and the terminal may be a smart phone. A tablet computer, a notebook computer, etc. may specifically be executed by a processing chip of a terminal, and the method specifically includes:
[0023] S110. Acquire memory frequency.
[0024] The memory frequency can be queried from the memory or read from the preset file. The preset document may be a document provided by a third-party application, such as a system configuration document provided by hardware management software. Different models of memory have different memory frequencies. For example: DDR1 memory freq...
Embodiment 2
[0037] figure 2 It is a flowchart of a global positioning system memory self-adaptive frequency multiplication method provided by Embodiment 2 of the present invention. Optionally, S110, the acquisition of memory frequency can be implemented in the following manner:
[0038] S111. Send a frequency acquisition instruction to the memory.
[0039] A central processing unit (Central Processing Unit, CPU) sends a frequency acquisition instruction to the memory. The frequency acquisition instruction may use existing frequency acquisition signaling.
[0040] S112. The receiving memory acquires the memory frequency of the instruction feedback according to the frequency.
[0041] Receive the memory frequency through the bus (BUS) to obtain the instruction feedback according to the frequency.
[0042] The memory frequency can be accurately obtained by sending the frequency acquisition command to the memory and receiving the memory return to the memory frequency. Compared with obtai...
