Intelligent television quick starting method based on dual-core starting and dual-core intelligent television

Technical Field

The invention relates to the technical field of quick startup of smart televisions, in particular to a method for quickly starting up a smart television based on dual-core startup and a dual-core smart television.

Background

With the development of the technology, the number of smart television products is gradually increased, and people can view the performance of the television more, so that the starting time of the smart television needs to be optimized, the smart television can be started more quickly, and the user experience is improved.

At present, each television manufacturer only uses a single-core starting system, but the existing intelligent television is generally provided with multiple cores, and obviously, the multi-core resources are not fully utilized in the starting stage of the intelligent television.

Therefore, how to optimize the turn-on time by using the multi-core resources of the smart television is a problem of intensive research of television manufacturers.

Disclosure of Invention

The invention aims to overcome the defects in the background art, and provides a dual-core start-based quick start-up method for an intelligent television, which divides the start-up boot stage task and the start-up of a kernel to two CPUs for parallel execution, thereby reducing the start-up time and achieving the purpose of starting the television more quickly.

In order to achieve the technical effects, the invention adopts the following technical scheme:

a fast starting method of an intelligent television based on dual-core starting comprises the following steps: the method comprises the steps that a main core CPU1 is started when the intelligent television is started, a CPU1 starts a slave core CPU2, the CPU1 and the CPU2 share the work and synchronously and independently execute a starting task, wherein the CPU1 is only used for starting kernel, the CPU2 is only used for running boot, and the kernel waits for the CPU2 to finish the task execution and then stops the CPU2 and runs Android;

according to the dual-core start-based quick start-up method for the intelligent television, a dual-core start-up method is adopted, and the task and the kernel start-up in the boot stage are divided into two CPUs to be executed independently and parallelly, so that the start-up time is reduced, and the problems that the intelligent television can only be started by using a single core and the start-up time is too long in the boot stage are solved.

Further, the method specifically comprises the following steps:

A. when the intelligent television is started, a main core CPU1 is started, and a CPU1 starts boot;

b, starting a slave core CPU2 after boot is started and setting a CPU2 running flag bit;

c, starting kernel by the CPU1, and running a boot related flow in the CPU 2;

reading the ATF, the hardware equipment state and the DTB file by the CPU1, filling the driving module of each peripheral according to the equipment list in the analyzed DTB file, and then operating the kernel;

the CPU2 runs all the tasks of the boot;

after the CPU2 executes the boot task, the kernel is automatically informed to take over the CPU2 and the running flag bit of the CPU2 is cleared;

G. and running Android.

Meanwhile, the invention also discloses a dual-core smart television which is specifically started by the starting method.

Compared with the prior art, the invention has the following beneficial effects:

according to the dual-core start-based quick start method for the intelligent television, boot and kernel are started through dual cores in the start stage, so that the start time is shortened, and the television can be started more quickly. Specifically, the smart television is powered on to start a master core CPU1, a CPU1 starts a slave core CPU2, the CPU1 and the CPU2 share the work and synchronously and independently execute a starting task, the CPU1 is only used for starting kernel, the CPU2 is only used for running boot, and the kernel stage waits for the CPU2 to execute the task and then takes over the CPU2 and runs Android. In the scheme of the invention, because the CPU1 and the CPU2 are used for synchronously executing the startup task in a division manner in the startup stage of the television, the startup time can be effectively reduced, and the purpose of starting the television more quickly is realized.

Detailed Description

The invention will be further elucidated and described with reference to the embodiments of the invention described hereinafter.

Example (b):

the first embodiment is as follows:

a fast starting method of an intelligent television based on dual-core starting comprises the following steps: the method comprises the steps that a main core CPU1 is started when the intelligent television is started, a CPU1 starts a slave core CPU2, the CPU1 and the CPU2 are in division synchronization and independently execute a starting task, wherein the CPU1 is only used for starting kernel, the CPU2 is only used for running boot, and the kernel waits for the CPU2 to finish the task execution and then stops the CPU2 and runs Android.

Specifically, as shown in fig. 1, the method of the present invention specifically includes the following steps:

step 1, when the intelligent television is started, a main core CPU1 is started, and a CPU1 starts a boot (namely a startup bootstrap program and a service module program);

step 2, starting a slave core CPU2 after Boot is started and setting a CPU2 running flag bit;

step 3, the CPU1 starts a kernel (Linux operating system, which is responsible for program scheduling, management of various hardware resources, and providing a basic operating environment for Android), and the boot-related process runs in the CPU 2;

step 4, the CPU1 reads ATF (Arm Trust Firmware, which is responsible for switching between Non-secure and secure), reads kernel hardware equipment state, reads and analyzes a DTB file, adds a driving module of each peripheral according to an equipment list in the analyzed DTB file, and then operates the kernel;

step 5, the CPU2 runs all the tasks of the boot;

step 6, after the CPU2 executes the boot task, the CPU2 automatically informs the kernel to take over the CPU2 and clears the running flag bit of the CPU 2;
