Detailed Description

•

Separate local memory bank within subsystem for I-code and d-code

–

192KB of Instruction code (I-code).

–

80KB of data space (D-code), split in 2 banks.

–

I-code and D-code can be mixed in any memory bank.

–

External world can access these memories if allowed via Firewall.

•

Firewall enabled 32-bits VBUSP CBA-SS interconnect

–

Low latency access from Cortex-M3 to ROM/RAM.

–

Cross-bar to allow Cortex-M3 and external host to access resources within DMSC.

–

Firewall policies enforced at each slave port to restrict access.

–

Channelized firewall for Message manager.

–

External 32-bits VBUSP master and slave interface

–

Address translation module to allow Cortex-M3 to reach any memory, with option Security

attributes.

•

Interrupts

–

Up to 80 input interrupts

•

Active high level or pulse interrupts – internally treated as asynchronous.

•

Capable of Waking up the DMSC and SoC from Standby mode.

•

Configurable Wakeup capability.

–

Interrupt Aggregator module for MiniNav and Main Nav interrupts

•

Four timer module

–

32-bits up counter.

–

64-bits can be achieved by cascading two timer modules.

•

One WW RTI module (watch dog timer)

–

RTI mode.

–

WatchDog

–

Issue cold/warm reset to SoC.

•

Debug

–

DAP based debug interface to Arm core.

–

Full debug support inside Arm core. All debug functionality is present including data matching for

watch point generation.

–

Standard trace support using ITM.

–

Limited Support for external Arm cross trigger interface (CTI) by providing interface signal to halt.

•

Fault Detection and Correction

–

Supports Double detection and Single error correction for I-code memory

–

Supports Double detection and Single error correction for D-code memory

–

Lock-Unlock based on 32bit keys for critical MMR writes.

–

Dedicated fault detected interrupt output.
