The RealView. Application Baseboard for the ARM926EJ-S core is a silicon-vendor independent software development board for the ARM926EJ-STM and PrimeXsys developer community. At the heart of the board is a highly integrated development chip which is based on the ARM926EJ-S PrimeXsys Platform architecture. External bus interfaces on the development chip, which enable bus layers inside the chip to be routed off-chip, allow additional peripherals to be added in an FPGA on the baseboard.
