DSP imprementation of Chen's equation

Specification

DSP	Texas Instruments TMS320C3x DSP Starter KIT (DSK)
	50MHz 32Bit floating point 25MIPS, 50MFLOPS
	internal RAM: 2K word
extensions	external SRAM: 32K word (256kBit * 4)
	16Bit stereo audio CODEC, sampling rate 4kHz-50kHz

Host specificaitons

CPU	Pentium2-300MHz
	Memory 160MB
OS	FreeBSD-4.1 or VineLinux-2.1
C compiler	gcc

We would like to emphasize that all DSP codes have been developed by only C language with GNU C/C++ compiler. No DSP assembler is needed. The authors also examined simulations on TMS320C6211DSK (fixed point DSP) by using Code Composer Studio 1.02.

Overview

scene of the laboratory experiment

We show snapshots of an analog synchroscope since the view of digital synchroscope is wearisome for a presentaion :-P Other chaotic autonomous system has been examined, e.g., Rossler, and Lorenz equation. Output of a linear combination of any state can be constructed easily.
