Motorola 6809

Dtasheet processors and microcontrollers. A micro-controller version with a slightly modified instruction set, thewas discontinued as late as the second decade of the 21st century.

Motorola spun off its microprocessor division in Hitachi produced its own based machines, the MB and later the S1.

Retrieved 2 April The CPU was also used in traffic signal controllers made in the s by several different manufacturers. Faster versions were produced later by Hitachi. In addition to home computers and game consoles, the was also used in a number of arcade games released during the early datasbeet mids.

The index and stack registers allowed advanced addressing modes. Datashet like the andthe uses a two-phase clock to gate the latches.

The division changed its name to Freescale and has subsequently been acquired by NXP. The very first Macintosh prototype, wire-wrapped by Burrell Smithcontained a Retrieved from ” https: The is sometimes considered to be the conceptual precursor of the Motorola family of processors, though this is mostly a misunderstanding: OS-9 Level II, also took advantage of such memory dtaasheet facilities. In fallQualcomm and NXP announced that they would merge. Retrieved April 22, However, there is a certain amount of design philosophy similarity e.

Since a CPU designer could hardly guarantee where this code would be located in a future system, the design focused heavily on support ofcode that could be freely located anywhere in the memory map. An example of standard ROM datzsheet might be binary floating point arithmetic, which is a common requirement in many systems.

However, the decisions 6b09 by the design team yielded a datashheet powerful processor and made possible 68b009 operating systems like OS-9 and UniFlexwhich took advantage of the position-independence, re-entrancy orientated nature of the to create multi-user multitasking operating systems. Drawing routines for graphics primitives, Lempel-Ziv LZ77 or LZ78 data compression and decompression, and string searching e.

It was a major advance over both its predecessor, theand the related. From Wikipedia, the free encyclopedia. Some instructions were replaced by more general ones which the assembler translated into equivalent operations and some were even replaced by addressing modes.

The design also focused on supporting reentrant code, code that can be called from various different programs concurrently without concern for coordination between them, or that can recursively call itself.

For yet another example, Motorola’s official programming manual [3] contains the full listing of assist09a so-called monitora miniature operating system intended to be burned in ROM.

Neither Motorola nor Hitachi produce processors or derivatives anymore.

Like theit included an undocumented address bus test instruction that would exceed the limits of some memory controllers, evoking the nickname [. It was similar in this to machines produced by, and several other suppliers. It was a major advance over both its predecessor, the Motorolaand the related MOS Technology Unlike contemporary processors that often used a microcoded architecture such as the and dataeheet thethe ‘s internal design was more similar to dztasheet simple CPU designs and to some degree also the RISC machines that appeared in the mid s and onwards.

Among the systems to use the are the Dragon home computers, TRS Color Computer datqsheet, the Vectrex home console, and early s arcade machines including DefenderRobotron: This article is based on material taken from the Free On-line Dictionary of Computing prior to 1 November and incorporated under the “relicensing” terms of the GFDLversion 1.

However, there is a certain amount of design philosophy similarity e. Some opcodes also live on in the Freescale embedded processors.

TSC produced a Unix-like operating system uniFlex which ran only on such machines.
