2 Hardware Overview
The micro-line® C6713CPU is a high performance DSP board that combines several key
technologies for high speed data processing:
•
a TMS320C6713 DSP with 256 KB internal fast SRAM and 225MHz or 300MHz CPU clock
(1800 MIPS / 1350 MFLOPS or 2400 MIPS / 1800 MFLOPS)
•
•
•
a Xilinx Spartan 3 FPGA with up to 1M gates
32 / 64 MB SDRAM in standard versions and 128 MB on request
2 MB flash memory for non-volatile program, data and FPGA design storage
The C6713CPU is available in different versions, regarding processor speed and memory size.
Please contact ORSYS or ORSYS distributors for the newest product list.
For proper operation of the micro-line® C6713CPU ORSYS recommends the desk carrier micro-
line® PowerSupply board which provides:
•
•
•
•
3.3 V regulated power supply for the C6713CPU
a 9-Pin SUB-D connector for the RS-232 interface
a reset button
Two isolated ±15 V DC/DC converters for peripheral I/O power supply (optional)
ORSYS furthermore offers complete development packages including Code Composer Studio,
XDS510 JTAG emulator/debugger or equivalent types and all necessary accessories like cables,
power supplies and software libraries.
This documentation describes the basic features of the C6713CPU. It does not include details of
the FPGA or the DSP. For further information about the FPGA, please refer to Xilinx [2]. For further
Many operational features of the C6713CPU require the use of a specific FPGA design, which is
provided by an according board support package (BSP).
The FPGA of the C6713CPU can be used either with the default BSP from ORSYS which is pre-
installed when the C6713CPU is shipped, or with individual custom designs using the FPGA
development option. The default BSP from ORSYS allows to operate the C6713CPU as a standard
micro-line® DSP board. In this case it is logically upward compatible to other existing micro-line®
products such as the C6711CPU (if the C6711CPU is operated with 3.3V only).

2.2 Connectors
2.2.1 micro-line® Connectors
The micro-line® connectors are the main I/O connectors of the C6713CPU. They provide access to
all signals that are needed for a wide range of I/O connectivity. The signals on the micro-line®
connectors can be grouped into the following categories:
•
•
•
power supply
DSP- and board specific interfaces, such as timers and serial ports
FPGA specific signals (their function depend on the respective FPGA design)
Historically (without FPGA) the micro-line® connectors carried the following signals:
•
•
•
power supply
DSP- and board specific interfaces, such as timers and serial ports
the micro-line® peripheral interface which allowed straightforward access to peripherals
Today, with FPGA technology onboard, many of the micro-line® I/O signals can be individually
hardware-configured for nearly any application. This is possible by building an individual,
application-specific FPGA design which exactly covers the application's requirements.
Nevertheless, the micro-line® standard peripheral interface is still available as a board support
package, the micro-line busmaster BSP®. It is the default configuration when the C6713CPU board
is shipped from ORSYS. The pinning of the micro-line® connectors (without any particular FPGA
design loaded) is described in chapter 6. The pinning and functionality of the micro-line® busmaster
2.2.2 JTAG Connector
The JTAG connector is used during development of application software or FPGA designs. It
contains two separate JTAG interfaces, one for the DSP and one for the FPGA.
The DSP JTAG interface is used for debugging and application software download during
development, together with Texas Instruments Code Composer Studio and an XDS510 (or similar)
emulator. After the software development is finalized, the user application software can be
downloaded from the development PC to the C6713CPU's flash memory via RS232 for permanent
storage. This is managed by the Flash File System which is permanently installed on the
C6713CPU.
The FPGA JTAG interface can be used to quickly download and test FPGA designs during
development without permanent storage on the C6713CPU. After the FPGA development is
finalized, the FPGA design can be downloaded from the development PC via RS232 to the
C6713CPU's flash memory for permanent storage. This is managed by the Flash File System
which is permanently installed on the C6713CPU.
In order to connect a standard DSP JTAG emulator or a standard FPGA download cable to the
C6713CPU, a JTAG adapter is used, which is included in C6713CPU development kits. The JTAG
adapter is described in chapter 6.4.
2.3 Interfaces and Hardware Components
2.3.1 FPGA
The default FPGA design for the C6713CPU can be used for standard micro-line® bus compatible
applications. Alternatively the FPGA can be individually programmed by the user. This is possible
by using an optional FPGA development package from ORSYS together with standard FPGA
development tools from Xilinx. FPGA technology allows flexible internal logic and individual I/O
