Embedded Microprocessor
An embedded microprocessor can be used to remotely
upgrade the System ACE MPM data sets. The embedded
microprocessor can program the Flash memory in the Sys-
tem ACE MPM using the native Flash memory interface to
directly control the Flash memory or the four-wire Boundary
Scan port.
The native Flash memory interface provides direct read
access, as well as write access, to the Flash memory. See
the AMD Flash memory data sheet for the proper Flash
memory programming protocol.
The FCM_ENABLE signal on the System ACE MPM must
be held Low during external access to the Flash memory.
Otherwise, contention between the microprocessor and
System ACE MPM configuration controller can occur.
The System ACE software can generate an SVF file for pro-
gramming a System ACE MPM Flash memory through the
System ACE MPM Boundary Scan interface. The Xilinx
application note (XAPP058) at:
(
http://www.xilinx.com/xapp/xapp058.pdf
)
provides reference C code and solutions for programming a
device through Boundary Scan from an SVF file.
Software Support
The standard Xilinx design flow is followed for the develop-
ment of the FPGA design sets. The Xilinx design software
packages are used to develop the design from which
.
bit
configuration file(s) are generated for each target FPGA.
The Xilinx PROM File Formatter tool is then used to compile
the .
bit
file(s) into a single image for downloading to a
Slave-Serial chain of FPGAs or to a single SelectMAP
FPGA. The output from the Xilinx PROM File Formatter is
an .
MCS
PROM image. The set of .
MCS
PROM images that
configure all of the target FPGA(s) connected to the System
ACE MPM is a called a design set.
The System ACE MPM can store up to eight data sets. The
System ACE software is used to compile multiple data sets
into a single Flash memory image. The Flash memory
image is stored as an
.MPM
file. The .
MPM
file is a standard
Intel Hex (.MCS) file. The assignment of each data set to a
target FPGA chain or SelectMAP device is defined within
the System ACE software.
The System ACE software can also program the final Flash
memory image into the System ACE MPM through a Xilinx
Parallel Cable III, or it can generate an SVF file for program-
ming the System ACE MPM using an alternate, Boundary
Scan-based programming method. Details of the System
ACE software are described in the
System ACE CF Tech-
nology Software User Guide
.
