Accelerate Visual Basic for Real Time Applications
QuBASE is a real time software accelerator for Visual Basic based on TI’s C3x/C6x family of floating point DSPs. QuBASE is fully compatible with VB .NET under all Windows 32/64 bit platforms. Currently, QuBASE works in conjunction with all Sheldon Instruments’ hardware which includes a full array of DSP accelerator cards and expansion modules with analog and digital I/O.
A slew of common functions have been coded in DSP assembly for ultra high performance. QuBASE has also been enhanced with less common but highly useful features such as Z Transforms for any system transfer function, classic and state space control algorithms, arithmetic and signal processing functions that are implemented on either a sample-by-sample basis or on an array of samples, adaptive filter algorithms, as well as DMA driven data exchange between the host processor and the DSP.
A typical QuBASE application allows the user to implement the following:
QuBASE is available for PCI, PC/104-Plus, PMC, and CompactPCI bus plug-in boards based on TI’s C3x/C6x family of DSPs. QuBASE is included FREE of charge when purchased with any data acquisition, control and DSP hardware from Sheldon Instruments. Please consult factory for adaptation to other manufacturer’s cards based on other DSPs. Development of new functions is available as QuBASE’s library is constantly being expanded.
