STX SRDP2

Overview 

Silicon Turnkey Express’s (STx) Serial RapidIO Development Platform2 (SRDP2) is a prototyping platform that leverage’s IDT’s RapidIO Gen2 switches. The SRDP2 has a variety of interfaces that allow customers to interface DSPs, Microprocessors, and FPGAs to IDT switches. Interfaces include AMCs, SMAs, InfinBand/CX4, SFP+ and QSFP connectors. This allows customer to implement most network configurations that represent their production hardware in a logically equivalent manner. By doing so, systems firmware and software engineers can start implementing their code before actual production hardware is available accelerating development cycles and time to market. 
 
Other purposes for the SRDP2 include interoperability testing, network performance benchmarking, or even simply learning more about RapidIO Gen2 in a hands on environment.
 
The SRDP2 comes equipped with RapidFET JTAG a software tool that can be used to configure IDT switches out of band via the JTAG interface on the board, making access to registers simple via a user friendly Graphical User Interface.
