Subsystem
The AUDMUX is a programmable interconnect for voice, audio, and
synchronous data routing between host serial interfaces (SSIs) and
peripheral serial interfaces (audio codecs). The AUDMUX has two
sets of interfaces: internal ports to on-chip peripherals and external
ports to off-chip audio devices. Data is routed by configuring the
appropriate internal and external ports.
The CAN protocol is primarily designed to be used as a vehicle serial
data bus running at 1 Mbps.
This block generates all clocks for the peripherals in the SDMA
platform. The CCM also manages ARM1136 platform low-power
modes (WAIT, STOP), disabling peripheral clocks appropriately for
power conservation, and provides alternate clock sources for the
ARM1136 and SDMA platforms.
This module is a serial interface equipped with data FIFOs (first in
first out); each master/slave-configurable SPI module is capable of
interfacing to both serial port interface master and slave devices. The
CSPI ready (SPI_RDY) and slave select (SS) control signals enable
fast data communication with fewer software interrupts.
ECT (embedded cross trigger) is an IP for real-time debug purposes.
It is a programmable matrix allowing several subsystems to interact
with each other. ECT receives signals required for debugging
purposes (from cores, peripherals, buses, external inputs, and so on)
and propagates them (propagation programmed through software) to
the different debug resources available within the SoC.
The EMI module provides access to external memory for the ARM
and other masters. It is composed of the following main submodules:
M3IF—provides arbitration between multiple masters requesting
access to the external memory.
SDRAM CTRL—interfaces to mDDR, DDR2 (4-bank architecture
type), and SDR interfaces.
NANDFC—provides an interface to NAND Flash memories.
WEIM—interfaces to NOR Flash and PSRAM.
Each EPIT is a 32-bit “set-and-forget” timer that starts counting after
the EPIT is enabled by software. It is capable of providing precise
interrupts at regular intervals with minimal processor intervention. It
has a 12-bit prescaler to adjust the input clock frequency to the
required time setting for the interrupts, and the counter value can be
programmed on the fly.
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
DSPs. The ESAI consists of independent transmitter and receiver
sections, each section with its own clock generator.
