1.2 Functional Overview of the TMS320C6416 DSK
The DSP on the 6416 DSK interfaces to on-board peripherals through one of two
busses, the 64-bit wide EMIFA and the 8-bit wide EMIFB. The SDRAM, Flash and
CPLD are each connected to one of the busses. EMIFA is also connected to the
daughtercard expansion connectors which is used for third party add-in boards.
An on-board AIC23 codec allows the DSP to transmit and receive analog signals.
McBSP1 is used for the codec control interface and McBSP2 is used for data. Analog
I/O is done through four 3.5mm audio jacks that correspond to microphone input, line
input, line output and headphone output. The codec can select the microphone or the
line input as the active input. The analog output is driven to both the line out (fixed
gain) and headphone (adjustable gain) connectors. McBSP1 and McBSP2 can be
re-routed to the expansion connectors in software.
A programmable logic device called a CPLD is used to implement glue logic that ties
the board components together. The CPLD also has a register based user interface
that lets the user configure the board by reading and writing to the CPLD registers.
The DSK includes 4 LEDs and 4 position DIP switch as a simple way to provide the
user with interactive feedback. Both are accessed by reading and writing to the CPLD
registers.
An included 5V external power supply is used to power the board. On-board switching
voltage regulators provide the 1.4V DSP core voltage and 3.3V I/O supplies. The
board is held in reset until these supplies are within operating specifications. A
separate regulator powers the 3.3V lines on the expansion interface.
Code Composer communicates with the DSK through an embedded JTAG emulator
with a USB host interface. The DSK can also be used with an external emulator
through the external JTAG connector.

Spectrum Digital, Inc
1.3 Basic Operation
The DSK is designed to work with TI’s Code Composer Studio development
environment and ships with a version specifically tailored to work with the board.
Code Composer communicates with the board through the on-board JTAG emulator.
To start, follow the instructions in the Quick Start Guide to install Code Composer.
This process will install all of the necessary development tools, documentation and
drivers.
After the install is complete, follow these steps to run Code Composer. The DSK must
be fully connected to launch the DSK version of Code Composer.
1) Connect the included power supply to the DSK.
2) Connect the DSK to your PC with a standard USB cable (also included).
3) Launch Code Composer from its icon on your desktop.
Detailed information about the DSK including a tutorial, examples and reference
material is available in the DSK’s help file. You can access the help file through Code
Composer’s help menu. It can also be launched directly by double-clicking on the file
c6416dsk.hlp in Code Composer’s docs\hlp subdirectory.

1.4 Memory Map
The C64xx family of DSPs has a large byte addressable address space. Program code
and data can be placed anywhere in the unified address space. Addresses are always
32-bits wide.
The memory map shows the address space of a generic 6416 processor on the left
with specific details of how each region is used on the right. By default, the internal
memory sits at the beginning of the address space. Portions of memory can be
remapped in software as L2 cache rather than fixed RAM.
Each EMIF (External Memory Interface) has 4 separate addressable regions called
chip enable spaces (CE0-CE3). The SDRAM occupies CE0 of EMIFA while the CPLD
and Flash are mapped to CE0 and CE1 of EMIFB respectively. Daughtercards use
CE2 and CE3 of EMIFA.

1.5 Configuration Switch Settings
The DSK has 3 configuration switches that allows users to control the operational state
of the DSP when it is released from reset. The configuration switch block is labeled
SW3 on the DSK board, next to the reset switch.
Configuration switch 1 controls the endianness of the DSP while switches 2 and 3
configure the boot mode that will be used when the DSP starts executing. By default all
switches are off which corresponds to EMIFB boot (out of 8-bit Flash) in little endian
mode. The figure below shows these settings.

1.6 Power Supply
The DSK operates from a single +5V external power supply connected to the main
power input (J5). Internally, the +5V input is converted into +1.4V and +3.3V using a
dual voltage regulator. The +1.4V supply is used for the DSP core while the +3.3V
supply is used for the DSP's I/O buffers and all other chips on the board. The power
connector is a 2.5mm barrel-type plug.
There are three power test points on the DSK at JP1, JP2 and JP4. All 6416 I/O
current passes through JP2 while all core current passes through JP1. All system
current passes through JP4. Normally these jumpers are closed. To measure the
current passing through remove the jumpers and connect the pins with a current
measuring device such as a multimeter or current probe.
The DSK provides +3.3V, up to 1A for the daughter card. The +3.3V supply is derived
from the +5V power source via the main +3.3 volt regulator. It is also possible to
provide the daughter card with +12V and -12V when the external power connector (J6)
is used.

2.1 CPLD (Programmable Logic)
The C6416 DSK uses an Altera EPM3128TC100-10 Complex Programmable Logic
Device (CPLD) device to implement:
• 4 Memory-mapped control/status registers that allow software
control of various board features.
• Address decode and memory access logic.
• Control of the daughter card interface and signals.
• Assorted "glue" logic that ties the board components together.
2.1.1 CPLD Overview
The CPLD logic is used to implement functionality specific to the DSK. Your own
hardware designs will likely implement a completely different set of functions or take
advantage of the DSPs high level of integration for system design and avoid the use
of external logic completely.
The CPLD implements simple random logic functions that eliminate the need for
additional discrete devices. In particular, the CPLD aggregates the various reset
signals coming from the reset button and power supervisors and generates a global
reset.
The EPM3128TC100-10 is a 3.3V (5V tolerant), 100-pin QFP device that provides
128 macrocells, 80 I/O pins, and a 10 ns pin-to-pin delay. The device is
EEPROM-based and is in-system programmable via a dedicated JTAG interface
(a 10-pin header on the DSK). The CPLD source files are written in the industry
standard VHDL (Hardware Design Language) and included with the DSK.

2.1.2 CPLD Registers
The 4 CPLD memory-mapped registers allows users to control CPLD functions in
software. On the 6416 DSK the registers are primarily used to access the LEDs and
DIP switches and control the daughter card interface. The registers are mapped into
EMIFB data space at address 0x60000000. They appear as 8-bit registers with a
simple asynchronous memory interface. The following table gives a high level
overview of the CPLD registers and their bit fields:
The table below shows the bit definitions for the 4 registers in CPLD.

2.1.3 USER_REG Register
USER_REG is used to read the state of the 4 DIP switches and turn the 4 LEDs on or
off to allow the user to interact with the DSK. The DIP switches are read by reading the
top 4 bits of the register and the LEDs are set by writing to the low 4 bits.
