BRIEF
RK3026
sensitive
Support different interrupt priority for each interrupt source, and they are always
software-programmable
DMAC
Linked list DMA function is supported to complete scatter-gather transfer
Support data transfer types with memory-to-memory, memory-to-peripheral,
peripheral-to-memory
Signals the occurrence of various DMA events using the interrupt output signals
Mapping relationship between each channel and different interrupt outputs is
software-programmable
One embedded DMA controller inperi system
DMAC features:
8 channels totally
13 hardware request from peripherals
2 interrupt output
Not support trustzone technology
1.2.6 Video CODEC
Video Decoder
Real-time video decoder of MPEG-1, MPEG-2, MPEG-4,H.263, H.264 , VC-1 , RV ,
VP6/VP8 , Sorenson Spark
Error detection and concealment support for all video formats
Output data structure after decoder is YCbCr 4:2:0 semi-planar to have more
efficient bus usage, For H.264, YCbCr 4:0:0(monochrome) is also supported
Minimum image size is 48x48 for all video formats
H.264 up to HP level 4.2 : 1080p@60fps (1920x1080)③
MPEG-4 up to ASP level 5 : 1080p@60fps (1920x1080)
MPEG-2 up to MP
: 1080p@60fps (1920x1080)
MPEG-1 up to MP
: 1080p@60fps (1920x1080)
H.263
: 576p@60fps (720x576)
Sorenson Spark
: 1080p@60fps (1920x1080)
VC-1 up to AP level 3
: 1080p@30fps (1920x1080)
RV8/RV9/RV10
: 1080p@60fps (1920x1080)
VP6/VP8
: 1080p@60fps (1920x1080)
For H.264, Image cropping not supported
For MPEG-4,GMC(global motion compensation) not supported
For VC-1, upscaling and range mapping are supported in image post-processor
For MPEG-4 SP/H.263/Sorenson spark, using a modified H.264 in-loop filter to
implement deblocking filter in post-processor unit
Video Encoder
Encoder only for H.264 (BP@level4.0, MP@level4.0,HP@level4.0) standard
Only support I and P slices, not B slices
Entropy encoding is CAVLC in BP and CABAC in MP
Support error resilience based on constrained intra prediction and slices
Maximum MV length is +/- 14 pixels in vertical direction and +/-30 pixels in
horizontal direction
Motion vector pixel accuracy is up to 1/4 pixels in 720p resolution and 1/2 pixels in
1080p resolution
12 intra prediction modes
Number of reference frames is 1
Maximum number of slice groups is 1
Input data format :
YCbCr 4:2:0 planar
YCbCr 4:2:0 semi-planar
