The DDB-VR5432 is a member of the North American RockHopper development system family. The SG-30541-2 and SG-MOTHER-2 pair is the Solution Gear II developmentr system for VR5432. Please note that in Japan and Asia, Solution Gear II is marketed instead of RockHopper which is software compatible with and similar to RockHopper. RockHopper systems are modular, with a common baseboard where the separate CPUcard connects via an edge connector to the PC board interface. The baseboard has PCI slots for cards and many standard peripheral interfaces. This is a highly efficient and flexible development environment featuring the capabilities of NEC's latest VR Series MIPS. embedded processors. RockHopper development systems are designed for evaluation of NEC processor and companion chip capabilities and for use as a reference design. The systems also support the full cycle of development and testing for peripheral hardware, device driver, and softwareapplications. The VR5432 processor is an efficient and highly cost effective choice for applications where hardware Floating Point performace is a requirement.
