Table 2-5. System modules (continued)
Module Description
Peripheral bridge (AIPS-Lite) The AIPS-Lite converts the crossbar switch interface to an interface that allows
access to a majority of peripherals on the device.
Direct memory access multiplexer
(DMAMUX) The DMAMUX selects from many DMA requests down to a smaller number for the
DMA controller.
enhanced Direct Memory Access
controller (eDMA) The eDMA provides programmable channels with transfer control descriptors for
data movement via dual-address transfers for 8-bit, 16-bit, 32-bit, 16-byte and 32-
byte data values.
TRGMUX The trigger multiplexer (TRGMUX) module allows software to configure the trigger
sources for various peripherals.
External watchdog monitor (EWM) The EWM is a redundant mechanism to the software watchdog module that
monitors both internal and external system operation for fail conditions.
Software watchdog (WDOG) The WDOG monitors internal system operation and forces a reset in case of
failure. It can run from an independent 128 kHz low power oscillator with a
programmable refresh window to detect deviations in program flow or system
frequency.
CRC Hardware CRC generator circuit using 16/32-bit shift register. Error detection for all
single, double, odd, and most multi-bit errors, programmable initial seed value, and
optional feature to transpose input data and CRC result via transpose register.
2.7.3 Memories and memory interfaces
The following memories and memory interfaces are available on this device.
Table 2-6. Memories and memory interfaces
Module Description
Local memory controller(LMEM) Manages simultaneous accesses to system RAM by multiple master peripherals
and core. Also provide cache control, which improves system performance by
providing single-cycle access to the instruction and data pipelines.
Miscellaneous System Control Module
(MSCM) The Miscellaneous System Control Module (MSCM) contains CPU configuration
registers and on-chip memory controller registers.
Flash memory • Program flash memory — non-volatile flash memory that can execute
program code
• FlexMemory — encompasses the following memory types:
• FlexNVM — Non-volatile flash memory that can execute program
code, store data, or backup emulated EEPROM data
• FlexRAM — RAM memory that can be used as traditional SRAM or as
high-endurance emulated EEPROM storage, and also accelerates
flash programming
QuadSPI The Quad Serial Peripheral Interface (QuadSPI) block acts as an interface to
external serial flash device. It supports SDR and HyperRAM modes up to 4 and 8
bidirectional data lines respectively.
Flash memory controller Manages the interface between the device and the on-chip flash memory.
SRAM Internal system RAM.
