DSP Libraries Update - November 2010
IntegrIT have a wide range of highly optimised libraries for Texas Instruments and Analog Devices DSPs and recently launched DSP signal processing libraries for Tensilica DSP cores. Libraries include NatureDSP Math and DSP Signal and APCO P25CAI for SDR applications plus audio codecs for wideband and narrowband VoIP.
Nature DSP Signal library is a collection of signal processing routines needed for implementation of typical algorithms for voice/audio processing. Special memory management optimizes performance and allows designer to utilize efficiently cache or DARAM/SARAM spaces and place most memory consuming blocks into the slow memory. Unique “filter-on-the-fly” feature enables fast filter synthesis in real time.
This library is available in binaries and in source code written on fully portable C-language for: Texas Instruments C54xx, C55xx, C64xx, OMAP, DaVinci, ARM7, ARM9 and ARM9E.
Another important feature is availability of bit exact library for x86 PC which makes development and simulation of complex DSP algorithms simpler and much more straight forward. |

NatureDSP Math library is a fixed point digital signal processing library. NatureDSP Math efficiently implements accurate fixed point representation of commonly used mathematic routines. NatureDSP Math saves product development time. It utilizes 100% of fixed point DSPs capabilities requiring minimum CPU cycles. The NatureDSP Math library is useful for signal processing algorithms developers and digital communication system designers.
Supported platforms include Texas Instruments C64/DaVinci, C55, ARM9E/ARM11 and Tensilica HiFi2 and ConnX D2. |
