SoC System Manager (SSM) Demonstration
- 1. INTERNAL or EXTERNAL ROM SoC SSM SoC System Manager ROM SSM COMMAND RAM SSM Controller : STATE MACHINE Configurable Embedded microcontroller to run SSM SSM CONTROLLER control scripts, system debug and optionally control system boot SSM COMMAND RESPONSE SSM OUT QUEUE QUEUE IN MCB: Module Control Block that attaches SSM to any or all modules in an SoC. May control power, clocks, reset, etc. at the hardware level and may communicate with software running on the module through mailboxes. Optionally may have MCB DSP ETHERNET MCB direct access to RAM modules for system boot and debug. May also be configured with counters to monitor and gather statistics on any part of the module. SSM Interconnect: Thin physical inteconnect between SSM controller and DRAM MCBs. May be configued as a MCB HOST MCB CONTROLLER ring, star or hierachy of both. SSM INTERCONNECT
