I) DSP circuit
DSP TMS320F28335 is a type ofTMS320C28X series
floating-point DSP controller produced by TI company.
Compared with fixed-point DSP, the chip TMS3-20F28335
has the character of higher precision, lower cost and power,
higher performance and peripheral integration, lager data
and program storage volume as well as faster and more
accurate A / D convert. Its inner power is 1.9V, and external
power is3.3V, therefore the power is reduced greatly. The
main frequency, which is up to 150 MHZ, and the
processing speed, are the ideal choice for portable products
which require floating point calculation.
It must be noted that when using memory map of
TMS320F28335:
l. The peripheral register block 0 to 3 on-chip is only
used for data store, users can not write the procedures in this
