Build 01 Specific Changes

Below is a list of changes and improvements specific to DADiSP 6.7 B01:

New Features and Functions

64 Bit Processing

DADiSP 6.7 B01 Win64 is a true 64-bit application. Although individual series are limited to a maximum length of 2 giga-samples, DADiSP 6.7 B01 Win64 has full access to all system resources. On 64-bit systems with a large amount of on-board RAM, setting a large series buffer with SETBUFSIZE allows a long series to remain resident in fast RAM, resulting in faster processing of big data.

On 32-bit systems, DADiSP 6.7 B01 Win32 is now Large Address Aware, providing access up to 4 GB of on-board RAM.

New ProPac Math Accelerator Module

The new DADiSP/ProPac Module combines the VectorXL module with the FFTXL and MatrixXL modules to provide a single, optimized numeric processing engine. Together, all three modules deliver accelerated vector math, FFT and matrix computations by using the Math Kernel Library from Intel. Speed improvements of 20% up to a factor of 50x are common.
