MELCOM70 MX5800

The MX5600, MX5700 and MX5800 super minicomputers from Mitsubishi Electric were high-end models in the MELCOM70 MX Series. They achieved high-performance and low power consumption by packing higher performance architecture into 20,000 gate and 11,000 gate CMOS VLSI. The MX5600 and MX5700 had arithmetic performance 3.3 times that of the MX/2600. They were equipped with a variable length 9-stage pipeline, an 80 megabyte/second high-speed bus, and a 256 kilobyte large-capacity cache memory. Overall processing capability was improved by increasing speed of double-precision arithmetic using a 64-bit arithmetic bus, and by using VLSI for the character/string processing which is frequently used in communications control and program development.
