• Format conversion and scaling
– Programmable color space conversion
– YUV422 to YUV444 conversion
– YUV444 to YUV422 conversion
– YUV422 to YUV420 conversion
– YUV444 Source: YUV444 to YUV444, YUV444 to RGB888, YUV444 to YUV422, YUV444 to
YUV420
– RGB888 Source: RGB888 to RGB888, RGB888 to YUV444, RGB888 to YUV422, RGB888 to
YUV420
– YUV422 Source: YUV422 to YUV422, YUV422 to YUV420, YUV422 to YUV444, YUV422 to
RGB888
– Supports RAW to RAW (no processing)
– Scaling and format conversions do not work for multiplexed input
• Supports up to 2047 pixels wide input - when scaling is engaged
• Supports up to 3840 pixels wide input - when only chroma up/down sampling is engaged, without
scaling
• Supports up to 4095 pixels wide input - without scaling and chroma up/down sampling
• The maximum supported input resolution is further limited by:
– Pixel clock and feature-dependent constraints
– For RGB24-bit format (RAW data), the maximum frame width is limited to 2730 pixels
For more information, see chapter Video Input Port of the device TRM
6.10.2 DSS
Display Port Interfaces (DPI) is available in DSS named DPI Video Output (VOUT).
VOUT interface consists of:
• 24-bit data bus (data[23:0])
• Horizontal synchronization signal (HSYNC)
• Vertical synchronization signal (VSYNC)
• Data enable (DE)
• Field ID (FID)
• Pixel clock (CLK)
For more information, see section Display Subsystem (DSS) of the device TRM.
6.10.3 Timers
The device includes several types of timers used by the system software, including 16 general-purpose
(GP) timers, one watchdog timer, and a 32-kHz synchronized timer (COUNTER_32K).
6.10.3.1 General-Purpose Timers
The device has 16 GP timers: TIMER1 through TIMER16.
• TIMER1(1ms tick): has its event capture pin tied to 32KHz clock and can be used to gauge the system
clock input and detects its frequency among 19.2, 20, or 27 MHz. It includes a specific functions to
generate accurate tick interrupts to the operating system and it belongs to the PD_WKUPAON domain
• TIMER2 and TIMER10: (1ms tick timers): they include a specific functions to generate accurate tick
interrupts to the operating system, TIMER2 and TIMER10 belong to the PD_L4PER domain
• TIMER3/4/9/11/13/14/15/16: they belongs to the PD_L4PER domain
• TIMER12 belongs to the PD_WKUPAON power domain
• TIMER5 trough TIMER8: belong to the PD_IPU module
