What does Tecsun mean by "DSP" ?

So in 2009 they are not offering a Shortwave
Radio with DRM ?
.

The DSP is digital signal processing. The processor reduces noise.

Actually, it can do way more than that. For instance, IF filtering in the
digital domain can potentially yield vitrual filters of continuously
variable bandwidth and perfect shape factors unattainable with ceramic or
crystal filters and at minimal cost. For more insight how this can be done
right, read the reviews of the Sony HD tuner - a $99 box with advanced DSP
functions which flat out beats any previously produced high-end AM/FM
tuner at any price.
