System Management
System management continues to gain importance in the design of
all electronic systems, since smaller process geometries drive more
multi-volt devices and are more susceptible to voltage and temperature
fl uctuations. System management tasks focus on maximizing system
uptime, identifying and communicating alert conditions and logging
data and alarm conditions. This can be combined with in-system
diagnostics and prognostics, not only to help debug systems that
have failed, but also to identify potential failures before they arise.
Thus, using a SmartFusion device as a system manager provides the
designer maximum implementation fl exibility.

Power Management
SmartFusion Mixed Signal Power Manager (MPM) offers a graphically
confi gurable power management solution that performs power rail
monitoring, power sequencing, closed-loop trimming, power-up and
power-down control and event data logging.

With complete PC-based GUI, source code and a fully
implemented reference design available for use with the
MPM Daughtercard to evaluate the full solution, the MPM
reference design also enables designers to integrate intelligent
confi gurable power management with their own Cortex-M3
fi rmware and FPGA design using SmartFusion devices.
Use the sample sequence engine in the ACE to manage system
health data collection.
Use the post-processing engine in the ACE to manage alert
condition fl ag generation.
Cortex-M3 only needs to make requests to the ACE and respond to
interrupts; no processing cycles needed.
Use FPGA gates for control algorithms when needed.
Communicate through I 2 C, UART, SPI or Ethernet for updates and
reporting.
Manages up to 32 power regulators
8 confi gurable PWM trimming outputs
32 general purpose digital outputs
Data logging to eNVM of critical events
I 2 C and JTAG confi guration updates
Interface
JTAG
Leveraging the considerable processing power of the ACE leaves the
Cortex-M3 and FPGA gates available for running the actual application
or communicating with the outside world. This not only eliminates the
need for multiple ASSP devices to perform system management, but
prevents system management from being an unnecessary burden on
the bill-of-materials (BOM) cost. Selecting SmartFusion devices for
system management provides fl exibility and reliability at the lowest total
cost of ownership (TCO).
