MTK 相机功耗拆解方法

科技 2024-08-13 07:30 上海

和你一起终身学习，这里是程序员Android

经典好文推荐，通过阅读本文，您将收获以下知识点:

一、硬件功耗
二、相机软件功耗
三、参考文档

一、硬件功耗

1.1 硬件信息

以下硬件信息最好提前获取到

模块	备注
平台	MTK or Qcom or sprd
CPU频率	大中小核
L2 Cache size	CPU缓存
DDR	DRAM 类型，品牌
屏幕	类型，品牌
相机Sensor	型号，出图size，帧率，几M

1.2 硬件功耗拆解

硬件电流一般需要使用功耗拆解板测试，使用功耗拆解版软件+工具可以拆解详细硬件模块的功耗，数据格式如下：

模块	备注
0_BAT
1_BB	CPU 功耗
2_MEMORY	内存
3_LCM	屏
4_AUDIO	多媒体
5_CAMERA	相机
6_RF	射频
7_WIFI	wifi
8_SENSOR	传感器
9_SIM	SIM 卡
10_USB	USB
11_PMU	电源管理单元
12_FLASH_LED	闪光灯

二、相机软件功耗

2.1 影响相机功耗的点

1.CPU 差异(MIPS百万指令每秒：可以准确的表现当时CPU的运算量)
2.Camera 模组差异
3.Camera APP 差异
4.Camera HAL 差异
5.Camera算法差异
6.PDAF差异
7.Camera Feature、SensorSize、RRZO Size、Camera FPS、P2 display size 、p2 preview callback size ，预览拍照 size 等差异
