L2330GC is DSP or not?

[Worfvx]

Hello,
i need know if this L2330GC or TMC2330 are DSP's or not.
In Specsheet Results are write - Digital Signal Processor - Coordinate Transformer.
Pls, see this site for datasheets and Specsheet Result http://www.datasheetarchive.com/

Very thanks for help

Seems they are not as a general DSP but a processor to do only polar conversions

from this pdf
http://www.andraka.com/files/supercn.pdf

There are a few specialty chips such as the TRW
TMC2330 and the GEC Plessey PDSP16330 designed
specifically for polar conversions.

and details from a US patent
http://www.patentstorm.us/patents/5450500/description.html

One possible hardware implementation, incorporated by reference herein, utilizes first the TRW model TMC2272 chip, which transforms the incoming RGB to YUV, which is a color space comprising luminance (Y) and two mutually orthogonal chrominance vectors U and V. The second stage is the TRW model TMC2330 chip, which mathematically transforms from rectangular (Y,U,V) to polar coordinates (H,S,L). Both of these chips are also usable in the reverse direction for conversion from HSL to YUV to RGB.

Thanx Neon_WA for this info.
