  2. PDP-14 - Wikipedia

    en.wikipedia.org/wiki/PDP-14

    The PDP-14 was designed to process Boolean equations, usually expressed as “ladder diagrams” and as such had a programmable read-only program memory. Programs were developed using a PDP-8 then tested using a direct connection to the PDP-14. The PDP-14 was put into a check out mode where instructions were provided by the PDP-8.

  3. PDP-11 architecture - Wikipedia

    en.wikipedia.org/wiki/PDP-11_architecture

    It is the successor to PAL-11 (Program Assembler Loader), an earlier version of the PDP-11 assembly language without macro facilities. MACRO-11 is supported on all DEC PDP-11 operating systems. PDP-11 Unix systems also include an assembler (called "as"), structurally similar to MACRO-11, but with different syntax and fewer features.

    Ford's internal code name for the TLCS-12 microprocessor was "PM-11" or "Poor Man's 11" implying it was a stripped down version of the, then popular, Digital Equipment Corporation PDP-11 computer. A PDP-11 was used in a vehicle in the first half of the 1970s for "proof of concept".

    An example IOMMU is the graphics address remapping table (GART) used by AGP and PCI Express graphics cards on Intel Architecture and AMD computers. On the x86 architecture, prior to splitting the functionality of northbridge and southbridge between the CPU and Platform Controller Hub (PCH), I/O virtualization was not performed by the CPU but ...
