| | Data General Nova - Wikipedia, the free encyclopedia |
 | | Data General developed a wide range languages for the Nova computers running under a range of consistent operating systems. | | | The Nova's biggest competition was from the newly-born DEC PDP-11 computer series, and to a lesser extent the venerable DEC PDP-8 systems. | | | Data General itself would later evolve into a vendor of Intel processor-based servers and storage arrays, eventually being purchased by EMC. |

| | A Brief History |
| | Developments between the mid 1930's and the early 1950's are commonly though of as the "first generation" of modern computers. | | | Machines such as the DEC VAX and Data General MV series have become "superminis." These processors differ from current mainframes principally in their less elaborate input-output processors and more limited capacity for data storage. | | | The Analytical Engine was intended to solve general arithmetic problems and introduced the concept of data storage. |

| | Minicomputer is a largely obsolete term for a class of multi-user computers which make up the middle range of the computing spectrum, in between the largest multi-user systems (mainframe computers) and the smallest single-user systems (microcomputers or personal computers). | | | The term evolved in the 1960s to describe the "small" third generation computers that became possible with the use of transistor and core memory technologies. | | | Today at the turn of the millennium few minicomputers are still in use, having been overtaken by Fourth Generation computers built using a more robust version of the microprocessor technology that is used in personal computers. |

| | All data that a computer processes must be encoded digitally, as a series of zeroes and ones. | | | In addition to the decimal format, computer data is often represented in binary (base 2), octal (base 8), and hexadecimal (base 16) formats. | | | While data is usually information resulting from or produced by a program, it can be the programs themselves. |

| | The 68020 (1984) expanded external data and address bus to 32 bits, simple 3-stage pipeline, and added a 256 byte cache (loop buffer), while the 68030 (1987) brought the MMU onto the chip (it supported two level pages (logical, physical) rather than the segment/page mapping of the Intel 80386 and IBM S/360 mainframe). | | | A microprocessor generally means a CPU on a single silicon chip, but exceptions have been made (and are documented) when the CPU includes particularly interesting design ideas, and is generally the result of the microprocessor design philosophy. | | | Program and Data memory were separate, 1K data memory and a 12-bit PC for 4K program memory (in the form of a 4 level stack, used for CALL and RET instructions). |

| | The Ultimate RISC |
| | In general, RISC machines are characterized by fixed format instructions and extensive use of pipelined execution, while CISC machines have variable length instructions and extensive use of microprogramming. | | | The Nova has an instruction set in which most instructions can execute in a single fixed-length cycle involving an instruction fetch, and one of either a fetch, a store, or an operation on registers. | | | Some early drum machines, such as the British DEUCE computer, circa 1955, encoded the data part of their instruction set as a series of move instructions, but these machines typically also included a next-address field in each instruction, making them quite different from pure move machines. |
