what type of processor is used in the pdp 11? - EAS
- The PDP-11 architecture is a CISC instruction set architecture (ISA) developed by Digital Equipment Corporation (DEC). It is implemented by central processing units (CPUs) and microprocessors used in PDP-11 minicomputers. It was in wide use during the 1970s, but was eventually overshadowed by the more powerful VAX-11 architecture in the 1980s.en.wikipedia.org/wiki/PDP-11_architecture

- All PDP-11's have a Processor Status Word register.The contents vary from model to model, but in all of them it contains: the four condition code bits; a bit to control 'trace' traps (which allow single-stepping the CPU); and the CPU's current priority level (to allow or defer peripheral interrupts). On models which provide memory management, there...
