Product Summary

The UPD30710RS-300 is a new member of NECs VR seriesTM RISC (Reduced Instruction Set Computer) microprocessors for UNIX servers, Windows NTservers, Desktop workstations, etc. The new high-performance 64-bit microprocessor UPD30710RS-300 employs a new RISC architecture developed by MIPSTM, ANDESTM architecture. The VR10000 and VR12000 are designed to be used in high-performance computers and achieve considerably higher processing speed through the employment of a super scalar pipeline.
