The document introduces the System Manager (SSM), the first SOC IP subsystem designed for efficient system resource management, addressing challenges in SOC architecture complexity. It highlights the advantages of SSM, including reduced development costs, enhanced software control, and improved hardware-software integration through high-level management governance. SSM also features capabilities for power and error management, streamlining development processes and enabling better coordination between hardware and software.

5. SSM Advantages
 Lowers development costs and risks
 Design and verify at architecture stage
 Pre-verify system management policies and reuse
 Increases the value of the SoC deliverable
 Improves software-system management control
 Mitigates hardware-software dependencies
 Creates new opportunities to innovate
 New power management schemes made possible
 Increasing integration complexities manageable
Shift System Management Out of the Design
and into the Architecture

6. The “Ripple Savings” Effect
 Architecture
 Top down system management provides high reuse framework for streamlining
product line management.
 Design
 Pre-defined topology eliminates creating ad hoc solutions during the design process.
 Verification
 Test schemes predesigned during architecture development accelerates starting
point for verification script generation.
 Software Development
 Shift to architecture significantly reduces burden to create similar solutions and
provides more chip behavior predictability before chip design commences.
 Bring Up and Test
 Provides unique post silicon control of IP cores for checkout and functional
verification. Scripts also a way to implement potential work-arounds.
 Production Engineering
 Consistent testing methodology throughout all phases of the development cycle
yields a comprehensive suite of testing sequences that are also easily modified.

9. SSM Use Models
 SSM facilitates the management of system resources such
as power management, security, error recover, and boot
and reset sequencing
 Control of these system resources, and the ability to
communicate directly with software, makes SSM an
excellent resource for many different uses:
 Hardware Development
○ Architecture Enhancement
 Top down system management provides high reuse framework for streamlining system
resource management across product lines
○ Design Acceleration
 Pre-defined topology within the architecture eliminates creating ad hoc solutions during the
design process.
○ Verification
 Test schemes predesigned during architecture development can be used to accelerate the
starting point for verification test generation.

 Software Development
 Shift to architecture significantly reduces burden to create similar system
management solutions in software and creates clear methodology for maintaining
synchronization between software and underlying IP hardware during operation
 Bring Up and Test
 Provides unique post silicon control of IP cores for debugging. Scripts also a way to
implement potential work-arounds to problems associated with IP block state
changes.
 Production Engineering Testing
 Consistent testing methodology throughout all phases of the development cycle yields
a comprehensive suite of testing sequences that are also easily modified.
 Remote Diagnostics and Updating
 SSM can deliver IP block state data to a remote host using a communications link or
a JTAG port for debugging and monitoring functions.
 SSM can be used to coordinate firmware and software updates remotely through the
use of its communications bus and connectivity to the IP blocks.

15. SSM Facilitates Policies
 Policies (chains of commands) accepted from any
source are loaded into local RAM
 Executes policy enforcement in any desired pattern
(called scripting)
 Guaranteed conditional or unconditional
enforcement sequencing
 Hardware uses message passing for IP block to block
communication
 Software uses drivers
Sequences of Commands Are Predetermined
and Tested For Any Number of Scenarios

16. Virtualizing System Management
 Typical Multicore Host Reset Script
 Suspend DSP; Send message to DSP O/S on DSP, Wait for ACK, toggle IP core
enable signal inactive
 Suspend MPE; Same as above
 Reset Host; Send message to host O/S, wait for ACK, toggle reset
 Resume DSP; Activate enable signal, send message to DSP O/S
 Resume MPE; Same as above
Software Scripts are Developed
Independent of Hardware Development
