J-11 chip set
The J-11 (formally, the DCJ11, although DEC documentation uses both names) is a high-performance CMOS implementation of the PDP-11 architecture, used in both the KDJ11 CPUs, and a variety of peripherals. It was implemented in two chips ('Control' and 'Data') carried on a single 60-pin DIP carrier.
It implements the full PDP-11 Memory Management architecture (with split Instruction and Data address space support, as well as Supervisor mode). Although it contains built-in FP11 floating point support (using microcode), it can operate with an optional FPJ11 floating point accelerator chip for higher performance.
