DPR Display/Prefetch/
Resolve
The DPR prefetches data from memory and converts the data to raster format for
display output. Raster source buffers can also be prefetched unconverted. The
resolve process supports graphics and video formatted tile frame buffers and
converts them to raster format. Embedded display memory is used as temporary
storage for data which is sourced by the display controller to drive the display.
DTCP Digital Transport
Content Protection
Provides encryption function according to Digital Transmission Content Protection
standard for traffic over MLB25/50.
eDMA Enhanced Direct
Memory Access
•4× eDMA with a total of 96 channels (note: all channels are not assigned; see
the product reference manual for more information):
•2× instances with 32 channels each
•2× instances with 16 channels each
• Programmable source, destination addresses, transfer size, plus support for
enhanced addressing modes
• Internal data buffer, used as temporary storage to support 64-byte burst
transfers, one outstanding transaction per DMA controller.
• Transfer control descriptor organized to support two-deep, nested transfer
operations
• Channel service request via one of three methods:
• Explicit software initiation
• Initiation via a channel-to-channel linking mechanism for continuous
transfers
• Peripheral-paced hardware requests (one per channel)
• Support for fixed-priority and round-robin channel arbitration
• Channel completion reported via interrupt requests
• Support for scatter/gather DMA processing
• Support for complex data structures via transfer descriptors
• Support to cancel transfers via software or hardware
• Each eDMA instance can be uniquely assigned to a different resource domain,
security (TZ) state, and virtual machine
• In scatter-gather mode, each transfer descriptor’s buffers can be assigned to
different SMMU translation
ENET Ethernet Controller 2× 1 Gbps Ethernet + AVB (Audio Video Bridging, IEEE 802.1Qav)
ESAI Enhanced Serial Audio
Interface
The Enhanced Serial Audio Interface (ESAI) provides a full-duplex serial port for
serial communication with a variety of serial devices, including industry-standard
codecs, SPDIF transceivers, and other processors. The ESAI consists of
independent transmitter and receiver sections, each section with its own clock
generator. All serial transfers are synchronized to a clock. Additional
synchronization signals are used to delineate the word frames. The normal mode
of operation is used to transfer data at a periodic rate, one word per period. The
network mode is also intended for periodic transfers; however, it supports up to 32
words (time slots) per period. This mode can be used to build time division
multiplexed (TDM) networks. In contrast, the on-demand mode is intended for
non-periodic transfers of data and to transfer data serially at high speed when the
data becomes available.
The ESAI has 12 pins for data and clocking connection to external devices.
FTM FlexTimer Provides input signal capture and PWM support
FlexCAN Flexible Controller Area
Network
Communication controller implementing the CAN with Flexible Data rate (CAN FD)
protocol and the CAN protocol according to the CAN 2.0B protocol specification.
