The Mercury Computer Systems / Themis USP IIi-3V is a 6U VME64 computing engine built on the Sun UltraSPARC IIi processor. It delivers 64-bit SPARC V9 performance at 360 MHz or 440 MHz for embedded systems, telecommunications, and real-time data processing applications requiring high availability and processing power. The platform combines substantial memory capacity, dual network interfaces, SCSI storage, and multiple serial I/O options in a compact VME form factor.
