2.1.3 - Signal levels
Regarding signal levels, the eZdsp is the only alternative that doesn’t support the standardized
[-10, 10] V by default – however, as part of a previous master thesis, a custom built interface
card has been fitted to the system in order to receive proper signal levels.
2.1.4 - Ethernet
Network connectivity is not of any main concern, though it is a nice feature mastered by
National Instruments. The APCI-3110 is only limited by the features of the PC it’s installed
upon so it should also be regarded as somewhat connected. The eZdsp F2812 on the other
hand – completely lacks this feature, the CPU-chip supports it however – and there are other
DSPs based on this that comes with an Ethernet connection.
2.1.5 - Mathworks integration
MATLAB has specific links for both DSpace and the eZdsp F2812, Code Composer Studio
actually. MATLAB also supports PCs as targets so the APCI-3110 should also be considered
to be somewhat integrated – it is unclear which compiler to use however since none are
included in the bundle, so it should therefore be considered possible but tiresome.
2.2 – The verdict
With all the factors above taken into account, the eZdsp F2812 from Spectrum Digital seems
to be very interesting to evaluate considering the needs and resources of the department.
