Overlay is the name that android often sees. It can be understood as video superposition, or overlay as video output.
Video output is closely related to video superposition. Generally, the output video background is the system UI Layer, while video output is superimposed on the UI Layer.
Video output and system UI generally use an independent video memory area. The system UI is displayed through framebuffer, while video output can be implemented in the driver layer in two ways: 1. framebuffer me

Startup Mode
MX51 supports four startup modes. These modes are determined by the solder joints on the IC Package (boot_mode 0/1). After reset, the two solder joints are sampled, then save their status to the SRC Boot Mode register (sbmr) Register. The solder joints correspond to logic 0. For logic 1, nvcc_per3 is recommended for Freescale.
The four boot modes are internal, reserved, internal b
through framebuffer, while video output can be implemented in the driver layer in two ways: 1. framebuffer method, 2. the output device Implementation Method of v4l2 is closely related to the platform, and even some platform implementation methods, such as Freescale imx51, the application layer can achieve video output through/dev/fb2, and set/dev/video16 through output to achieve video output. Which of the following is the work of overlayhal.

In the PC field, Intel and windows are still strong. However, in the mobile device field, mobile phones and emerging tablet computers are mainly used. Intel is insufficient in strength and arm is taking the lead, almost monopolized. Intel has no food to eat, windows is naturally not good. Given arm's strength in the mobile field, Ms had to advertise support for ARM processors in Windows 8.

At the seminar, the two schemes were completely different. One uses a general chip, such as DSP, arm9-and FPGA, and one uses a dedicated chip, such as a copy, scan, and fax integrated chip. The two solutions have their own advantages and disadvantages:
The general-purpose chip has the following advantages:
1. It is easy to purchase chips. Not only depends on one model. Any MCU can. The nxp arm chip can be used, the Atmel chip can also be used, and the Freesc
