64-bit computing more generally "multi-arch support". 64-bit computing In computer architecture, 64-bit computing is the use of processors that have datapath widths, integer size, and memory address widths of 64 bits (eight octets). Also, 64-bit computer architectures for central processing units (CPUs) and arithmetic logic units (ALUs) are those that are based on processor registers, address buses, or data buses of that size. From the software perspective, 64-bit computing means the use of code with 64-bit virtual memory addresses. However, not all 64-bit instruction sets support full 64-bit virtual memory addresses; x86-64 and ARMv8, for example, support only 48 bits of virtual
Byte (magazine) reminiscent of the Keystone Cops, "Byte" magazine finally has moved into separate offices of its own." Wayne Green was not happy about losing "Byte" magazine so he was going to start a new one called "Kilobyte". "Byte" quickly trademarked KILOBYTE as a cartoon series in "Byte" magazine. The new magazine was called "Kilobaud". There was competition and animosity between Byte Publications and 73 Inc. but both remained in the small town of Peterborough, New Hampshire. Articles in the first issue (September, 1975) included "Which Microprocessor For You?" by Hal Chamberlin, "Write Your Own Assembler" by Dan Fylstra and "Serial Interface"
