  Zilog Z8000 - Wikipedia, the free encyclopedia
The Z8000 was a 16-bit microprocessor introduced by ZiLOG in 1979.
Like the Z80, the Z8000 included builtin DRAM refresh circuitry, but although an attractive feature for designers of the time, overall the Z8000 was not especially fast and had some bugs, and in the end it was overshadowed by the x86 family.
One notable use of the Z8000 series was by Namco in the design of its famous Pole Position series of racing videogames.

 Zilog Z80000 - Wikipedia, the free encyclopedia
It could execute code written for the Z8000, but was not compatible with the Intel x86 architecture, nor was it Z80 compatible.
Sixteen general-purpose registers of variable size were available through use of a 64-byte "register file." The processor included a memory management unit that provided protected memory, important for multitasking, and virtual memory addressing for temporary storage of RAM on a hard disk.
The processor was designed to interoperate with other integrated circuits designed for use with the Z8000, such as the Zilog Z8070 floating-point coprocessor.

Internally, the Z8000 had sixteen 16-bit {registers}, but register size and use were exceedingly flexible.
They were all general purpose registers - the {stack pointer} was typically register 15, with register 14 holding the stack segment (both accessed as one 32-bit register for painless address calculations).
The Z8000 featured two modes, one for the {operating system} and one for user programs.

 The Z8000 / Z80,000 / Z16C00 CPU homepage
The Z8000 CPU series has been Zilog's contribution in the "Processor War" (i.e the competition between various 16-bit microprocessor designs during 1978-1985, before the Intel 80*86 family came out as the winner), and was introduced in 1979 between the 8086 CPU (Intel) and the 68000 CPU (Motorola).
The Z8000 CPUs appeared in two versions; a large memory version (Z8001) with 8 Mbyte addressing capability, and a small memory version (Z8002) with 64 Kbyte addressing capability.
Although initially the Z8000 got some acceptance and was widely recognised to have a very elegant and user-friendly architecture, it became quickly surpassed by the Motorola 68000 and the Intel 80286 in the commercial domain.

 OLD-COMPUTERS.COM : HISTORY / detailed info
The Z8000 CPU series was introduced in early 1979, between the launch of the Intel 8086 (April 1978) and the Motorola 68000 (September 1979).
Internally the Z8000 chip held 17500 transistors in NMOS design, and it had sixteen 16 bit registers which could be extremely flexibly used.
The Z8000 was followed in 1986 by the Z80000, an amazing 32 bit processor whose features (pipeline, cache memory) would not appear until six years later in Intel processors.

 Using as - Z8000 Dependent Features
The Z8000 as supports both members of the Z8000 family: the unsegmented Z8002, with 16 bit addresses, and the segmented Z8001 with 24 bit addresses.
Direct: the 16 bit or 24 bit address (depending on whether the assembler is in segmented or unsegmented mode) of the operand is in the instruction.
The Z8000 port of as includes these additional assembler directives, for compatibility with other Z8000 assemblers.

Z8000 Dependent Features ======================== The Z8000 as supports both members of the Z8000 family: the unsegmented Z8002, with 16 bit addresses, and the segmented Z8001 with 24 bit addresses.
When the assembler is in unsegmented mode (specified with the `unsegm' directive), an address takes up one word (16 bit) sized register.

 Software for the Z8000 / Z16C00 CPUs
Although the software base for the Z8000 CPU is very limited, I got some very useful information from some kind people who emailed me with concrete links.
The ZASM software does not include documentation on assembler directives, so for the Z8000 I have made an example assembler code file, a batch file that I use to generate listings and object code, and list and code files.
The resulting code may be transferred to a z8000 sytem using the HyperTerminal application in Windows, for example.

For the Z8000 family, `target sim' simulates either the Z8002 (the unsegmented variant of the Z8000 architecture) or the Z8001 (the segmented variant).
The simulator recognizes which architecture is appropriate by inspecting the object code.
You can refer to these values in GDB expressions with the usual conventions; for example, `b fputc if $cycles>5000' sets a conditional breakpoint that suspends only after at least 5000 simulated clock ticks.
