The had a small byte direct-mapped instruction cache, arranged as 64 four-byte entries. The UX shipped with Amiga Unix, requiring an ‘ or ‘ processor. All other processors had to hold off memory accesses until the cycle was complete.
It also found use in laser printers. For more information on the instructions and architecture see Motorola The Nortel Networks DMS telephone central office switch also used the as the first microprocessor of the SuperNode computing core. A lower cost version was also made available, known as the 68EC The previous and processors could only access word bit and long word bit data in memory if it were word-aligned located at an even address. 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.
It is also the processor used on board TGV trains to decode signalling information which is sent to the trains through the rails. Newer packaging methods allowed the ‘ to feature more external pins without the large size that the earlier dual in-line package method required. The replaced this with a proper instruction cache of bytes, the first 68k series processor to feature true on-chip cache memory.
Although small, it still made a significant difference in the performance of many applications.
The has a coprocessor interface supporting up to eight coprocessors. The added many improvements over the including a bit arithmetic logic unit ALUbit external data and address buses, extra instructions and additional addressing modes. Under the and later, this was made privileged, to better support virtualization software. This page was last edited on 5 Septemberat Wikimedia Commons has media related to Motorola The had bit internal and external data and address buses, compared to the early x0 models with bit data and bit address buses.
Fixed branch prediction, branch-never-taken approach . While the had ‘supervisor mode’, it did not meet the Popek and Goldberg virtualization requirements due to the single instruction ‘MOVE from SR’ being unprivileged but sensitive. Unsourced material may be challenged and removed.
The 68EC is a lower cost version of the Motorola Please help improve this article by adding citations to reliable sources.

Retrieved from ” https: It is further being used in the flight control and radar systems of the Eurofighter Datasyeet combat aircraft. It is the successor to the Motorola and is succeeded by the Motorola The and had a proper three-stage pipeline. InRochester Electronics has re-established manufacturing capability for the microprocessor and it is still available today. The datahseet ALU was also natively bit, so could perform bit operations in one clock, whereas the took two clocks minimum due to its bit ALU.
This article needs additional citations for verification.

The coprocessor interface is asynchronous, so it is possible to run the coprocessors at a different clock rate than the CPU. Though the had a “loop mode”, which sped loops through what was effectively a tiny instruction cache, it held only two short 6020 and was thus little used. Fundamentals of Digital Logic and Microcomputer Design. From Wikipedia, the free encyclopedia. In other projects Wikimedia Commons. The had no alignment restrictions on data access.
The main CPU recognizes “F-line” instructions with the four most significant opcode bits all oneadtasheet uses special bus cycles to interact with a coprocessor to execute these instructions.
To avoid problems with returns from coprocessor, bus error, and address error exceptions, it was generally necessary in a multiprocessor system for all CPUs to be the same model, and for all FPUs to be the same model as well. The HP, and also use thetogether with a math coprocessor.
