Data Formats

Sixteen-bit words were stored little-endian (with least significant bytes first). Due to the popularity of the PDP-11, this format is still sometimes referred to as pdp-endian. Thirty-two-bit data—supported as extensions to the basic architecture, e.g., floating point in the FPU Instruction Set, double-words in the Extended Instruction Set or long data in the Commercial Instruction Set—was stored in more than one format, including an unusual middle-endian format.

Famous quotes containing the word data:

    Mental health data from the 1950’s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isn’t surprising. If society tells you that your main role is to be attractive to men and you are getting crow’s feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.
