Description
The VSP 94x2A (PRIMUS) is a new component of the Micronas MEGAVISION® IC set in a CMOS embedded DRAM technology. The VSP 94x2A comprises all main functions of a digital featurebox in one monolithic IC. The number of features is limited in favor of a lowcost solution, but no trade-off has been made concerning picture quality.
