21. DISPLAY

21.1 Introduction

The SP7021 video display function support video input source from camera, after data processed by CPU than output to HDMI. The video input can be MIPI_CSI or USB. SP7021 can support two channels MIPI_CSI camera. This module also supports directly raw data transfer to add efficiency. The Display Mixer function can mix one layer OSD and VPP data. The display output format support HDMI1.4 spec, HD resolution and YUV444 mode. The video display control registers locate at RGST Group 185~235 which memory map address are 0x9C005C80~0x9C0075FF.

21.4 DFCH (Data Fetch)

DFCH block also can be named DDFCH (De-interlace Data Fetch) due to its de-interlace function. The main function is fetched data from DRAM. There may be several types of data sources, and various formats are internally transmitted to the corresponding subsequent IP processing (VPOST). The features include below list.

21.5 VPOST (Video Post)

The VPOST block is kernel of video processor. It accepts two input sources, one is DMA input with YUV422 32bits format, another one is DDFCH input with YUV422 16bits format. This block will output data to DMIX block with YUV444 / Alpha 8 bits format. The VPOST functional block diagram is shown in figure 21-3.

Figure 21-3 VPOST Functional Blocks

RGST IFX: This block will decode the control registers for VPOST.
LBUF: LBUF block do line buffer to avoid DMA data less than real time. The SRAM is shared with DDFCH block.
BIST: There are two functions in BIST block, they are Path Selection and Internal Pattern. The Path Selection can select input signal come from DMA or DDFCH, where the DMA data is 32 bits and must be converted to 16 bits.
UPS: Chroma up sample 422 to 444.
DCTRL: This block support cropping and padding. Once the original image is different from the resolution of the output image, the crop/padding function is used for output without scaling.
OPIF: Interface between Req/Valid protocol and TGEN timing protocol.

21.6 OSD (On Screen Display)

OSD is the hardware providing bitmap display layer overlaying over or under other video and graphics display. This hardware is controlled by firmware through the register-file interface. If OSD enabled, it will read a linked-list data structure from the main-memory and output is sent to GSCL to scaling for compressing or directly display. Application may use this hardware to show user-interface message visually. The data support following color format.

32-bit RGBA8888/ARGB8888
16-bit RGB565/ARGB1555/RGBA4444/ARGB4444/YUY2
8-bit color index mode with CLUT GBRA8888/YCbCrA8888/ARGB8888

21.9 TGEN (Timing Generator)

TGEN(Timing Generator) is mainly responsible for generating of control timing for each module including field start, field end, field ID, display start pulse and pixel enable signal.
DTG, standing for Display Timing Generator, is the module that generates the control timing for modules dealing with display video formats. The Display Timing is generated according to the display video format. Display timing is the master timing of the whole system. If the display video format remains unchanged, display timing must be continuous. Even if the source video resolution changes, or if the configuration of display scaler changes.
The TGEN functional block diagram is shown in figure 21-6.
