Data unit

31-bit computing

In computer architecture, 31-bit integers, memory addresses, or other data units are those that are 31 bits wide. In 1983, IBM introduced 31-bit addressing in the System/370-XA mainframe architecture as an upgrade to the 24-bit physical and virtual, and transitional 24-bit-virtual/26-bit physical, addressing of earlier models. This enhancement allowed address spaces to be 128 times larger, permitting programs to address memory above 16 MB (referred to as "above the line"). Support for COBOL, FORTRAN and later on Linux/390 were included. In the early 1980s, the Motorola 68012 was introduced; it had 32-bit data and address registers, as the Motorola 68010 did, but instead of providing the lower 24 bits of an address on the address pins, it provided all but bit 30 on the address pins.

Designing and building a 1-bit register - 8 bit register - Part 3

Before we build the 8-bit registers for our computer, let's design and build a 1-bit register. The 8-bit registers we'll actually use in our 8-bit computer will be simplified. We're going to take a big shortcut—using the 74LS173—described at the end of this video. But before we get to tha
