Area descriptors (AD)
defines areas of interest
(AOI) on a plane
Each AOI has its own
independent definition
specified by the AD
Planes can have unlimited
AOIs as long as they do not
share a horizontal scan line
DIU accesses ADs in
vertical order using a linked
list of pointers to the next
AD
Only pixels within AOIs are
fetched by the DIU using the
format specified in the AD
AD linked lists can be
manipulated to change
plane content and move an
AOI between planes

Other Considerations
− Memory
bandwidth of input pixel data
ƒ
Only pixels within defined AOIs consumes bandwidth
ƒ
Independent pixel format can be defined for each defined AOI
− Memory
access burst patterns
ƒ
AOIs must be at least 4 lines, each line containing at least 8-bytes of
pixel data
ƒ
Recommend AOI sizes of at least 256 bytes and a few lines between
AOIs to improve performance
− DIU
priority over shared memory so that input pixel buffers do
not run empty

ALSA needs to know how often to write to the buffers (RAM)
Application communicates to ALSA and ALSA starts
writing to the buffers
ALSA tells the SSI and DMA to start
DMA starts reading from the buffer at the sample rate and
issues interrupt to tell ALSA to fill the buffers as it goes
along
DMA fills the SSI FIFOs which can tell it to start/stop based
on the watermark
SSI pushes the data out to the Codec at sample rate

P1022 is the first QorIQ device with DIU and SSI support
LCD display for embedded applications (up to SXGA or
720p) without external display controller
The signals of DIU and eLBC are muxed on same pins.
When DIU is used, only 8-bit data/address are available
for eLBC
SSI supports I2S and AC’97 modes
