計算Mel倒譜系數的matlab程序:
MELCEPST Calculate the mel cepstrum of a signal C=(S,FS,W,NC,P,N,INC,FL,FH)
使用: c=melcepst(s,fs) % calculate mel cepstrum with 12 coefs, 256 sample frames
This a FREE tool chain which compiles C codes into 8051 binary code, converts the binary to RTL ROM, and simulate in Modelsim.
SDCC is the compiler.
Example compilation:
cd compile
sdcc --iram-size 0x80 --xram-size 0x800 t8051.c
REM sdcc --iram-size 0x80 t8051.c
packihx t8051.ihx > t8051.hex
..\test\mkrom.exe ..\compile\t8051.hex

HsGpsDll Library 1.1
A GPS Control/Component for C/C++
HsGpsDll is a Windows Dynamic Link Library which provides access to any NMEA-183 compliant GPS receiver via a serial communications port. HsGpsDll is designed for use from Visual C, Visual Basic or other languages, capable of calling DLL functions. HsGpsDll allows a user application to read from a GPS device the current GPS position fix, velocity over ground (speed in kilometers per hour), plus number of of sattelites in view, current altitude (against mean sea level) and UTC date and time
