In-Depth Information
on a variety of platforms (provided there is a C compiler for a given archi-
tecture and instruction set). In CCS, the C compiler has four optimization
levels. The highest level of optimization does not achieve the same level of
optimization that programmer-optimized assembly programs does, but TI
has done a good job in making the optimized C compiler produce code that
is comparable with programmer-optimized assembly code.
Finally, a hybrid between assembly language and C exists within CCS. It
is called
linear assembly code
. Linear assembly looks much like assembly
language code, but it allows for symbolic names and does not require the
programmer to specify delay slots and CPU core registers on the DSP. Its
advantage over C code is that it uses the DSP more efficiently, and its advan-
tage over assembly code is that it does not require the programmer to manage
the CPU core registers.

Software/Hardware Laboratory Using the TI
TMS320C6711 DSK
7.2.1
Software and Hardware Equipment Requirements
For most exercises in this laboratory, the following equipment will be needed
at every lab station:
•
A Pentium-based computer with CCS version 2.0 or greater installed
on it
•
A 'C6711 DSK including power supply and parallel printer port cable
•
Two coaxial cables with an 1/8-inch stereo headphone male jack on
one end and two BNC male connectors (RF connectors) on the other
end
•
A set of speakers or headphones
•
One coaxial cable with 1/8-inch stereo headphone jacks on both ends
•
A signal generator
•
An oscilloscope
7.2.2
Initial Setting Up of the Equipment
•
Connect the parallel printer port cable between the parallel port on
the DSK board (J2) and the parallel printer port on the back of the
computer.
•
Connect the 5V power supply to the power connector next to the
parallel port on the DSK board (J4). You should see 3 LEDs blink
next to some dip switches.
