Digital Signal Processor  DSP is new generation of multiple function processor, high integration for one chip solution to meet all small size of consumer electronics requirements, new concept of S.O.C. system on chip is help for short time development and mass production, according to the common working platform, we prepared many application unit for market valuable function for customer design reference, to help for design stage and time to market.

Body Sense : Using P21K DSP , different to usually  P.I.R. infrared way, we use one 1_cm square to detect body electrical field, it also can be by PCB layout for human touch detective, high sensitive for body electrical force by digital data output.  < Bull Dog Introduction.htm >

Sound Point Detector : Using P25K DSP, Mic R/L array to detect voice source and calculation azimuth data,  sound array can trace voice source and auto correcting for mismatch. < Snd 360 Techinfo.pdf >

Communications : Providing DSP chip communication with PC Windows by RS-232 , Parallel port , I2C .... communication interface.

DTMF Tone Generator : Providing DTMF generator, for codeless phone and voice dialer application.
