This paper describes the hardware features and performance improvement techniques employed in the central processing unit of the new DIPS-11/5E series. Internal performance is 2. 5 to 3 times higher than that of the earlier DIPS-11/5 series thanks to use of advanced high-speed, high-density logic LSIs (2000-5000 gates/chip), as well as improved hardware architectures. Extensive LSI also use results in lower power consumption, more compact size, and greater reliability. The dyadic configuration allows each model to be upgraded over a wide range. DIPS architecture has been extended while maintaining compatibility with earlier models. New features are an extended addressing architecture, and high-speed virtual machine functions supported by hardware.
