STR91x DSP library (DSPLIB)

Introduction

This manual presents a library of ARM assembly source code modules for digital signal

processing (DSP) applications such as infinite impulse response (IIR) filter, finite impulse

response (FIR) filter and fast Fourier transform (FFT) applicable for a range of DSP

applications including VSLP vocoder. These assembly source code modules are presented

for ARM mode and have been tested in an ARM9E-based STR91x platform.

In addition, the assembly source code modules have been tested in an IAR Workbench

environment as well, but STMicroelectronics cannot guarantee that these assembly source

code modules will be flawless for all applications.

The algorithm modules are presented "as is with no warranty".
