At Texas Instruments, audio products range from mixed-signal devices such as audio codecs and analog-to-digital converters to single-core DSP chips
. So the company can help engineers with portable battery powered audio devices as well as with amplifiers for 100-watt speakers.
Today's DSP chips
will invariably contain a multiplier; on-board random access memory (RAM) for data storage; and read-only memory (ROM) for fixed-coefficient storage.
* Power consumption -- e.g., millions of floating point operations per second (MFLOPS) per watt, an important military consideration -- is less in the DSP chip
The speed of these operations depends on a variety of factors: DSP chip
speed, the number of taps, and the number of bits of accuracy in each computation.
A company that claims to have produced accurate pattern recognition algorithms so tight that they can be fitted on an 8-bit smart card or in spare capacity on a DSP chip
on a mobile phone is beefing up its management team in a drive to penetrate new markets.
However, to prevent a decrease in CPU and modem performance a separate, and less expensive, DSP chip
is used to share the load.
Blue Wave Systems has launched new DSPs based on the C6000 DSP chip
and its new dual processor PCI/C6600 DSP board.
When a buffer fills, data are downloaded tea DSP chip
through a 16 MB/sec port.
"You might implement something on a DSP chip
today and move it to an ARM processor in a few months.
This depends on whether the onboard processor is a DSP chip
or conventional (Pentium-class) CPU.
Many factors affect whether or not you can make use of a DSP chip
for your DAQ application: Extremely low and very high sampling rates may present particular problems.
Although application-specific devices can apply voltages to a DSP chip
in a set sequence, they cannot perform other functions.
