 ZiLOG   (Site not responding. Last check: 2007-10-13)
ZiLOG, often seen as Zilog, is a manufacturer of 8-bit CPUs, and are most famous for their Intel 8080-compatible Z80 series.
Zilog was incorporated in California in 1974 by Federico Faggin, who left Intel after working on the 8080, and the Z80 shared many features with it.
Later Zilog introduced 16-bit and 32-bit processors, but these were not particularly successful, and the company refocussed on the microcontroller market, producing both basic CPUs and application-specific standard products (ASSPs) built around a CPU.

Although Zilog made several attempts to move off the Z80 onto more powerful 16-bit (Zilog Z800, Zilog Z8000, Zilog Z180, Zilog Z280) and 32-bit (Zilog Z80000, Zilog Z380) platforms, other companies were offering CPUs in this performance range years earlier, and the Zilog chips never caught on.
Zilog’s most recent CPU is the Zilog eZ80, a faster Z80 with a 24 MB addressing range.
The Zilog Z80 has also become a popular embedded microprocessor and microcontroller core, where it remains in widespread use today.

 Zilog Z8000   (Site not responding. Last check: 2007-10-13)
The Z8000 was a 16-bit microprocessor introduced by ZiLOG in 1979.
Like the Zilog 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.
The Zilog Z80000 was a 32-bit followon design.

 Zilog Z80000
The Z80000 was Zilog's 32-bit processor from 1986, an expansion of its 16-bit predecessor, the Zilog Z8000.
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.

 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.
Zilog also designed a UNIX "supermicro" system called the S8000 initally based on the Z8000, then the Z80000 with a UNIX based OS called Zeus.

Zilog was founded in 1974 and became a wholly owned subsidiary of Exxon Corp. by 1980.
Zilog now produce a range of 8-bit microcontrollers, 8-, 16- and 32-bit microprocessors, and digital signal processors, covering the home entertainment, communications, and embedded systems markets.

 Zilog Z80 - CompWisdom
Zilog shrunk (they were once owned by Exxon!) because they went from 1 8 bit Z80 hugely successful processor to a pure 16 bit processor (Z8000?).
Zilog has added more instructions and changed mnemonics, but the basic core of instructions works the same and has the same opcodes in both 8080 and Z80.
Zilog adopted a different (and more logical) set of mnemonics, possibly because Intel claimed that the 8080 mnemonics were copyrighted.

 CPU-World: Zilog Z8000 microprocessor family
Zilog Z8000 is a family of 16-bit microprocessors comprising of 4 processors with slightly different features:
The Zilog Z8000 processors have separate code, data and stack memory space.
Memory management and protection features for the Zilog Z8000 are provided by Z8010 MMU.

 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.

 ZiLOG, Inc.
Formed in the mid-1970s, ZiLOG was a trailblazer in the semiconductor industry and a pioneer of the California high-tech hotbed known as Silicon Valley.
ZiLOG was also slow to bring out the complementary software that potential users of the chip needed to incorporate the microprocessors into their electronics products, and as a result the company was unable to capitalize on its established market presence to counter its late start.
ZiLOG's financial performance quickly began to improve, with the company posting its first profit in 1986 after several years of consecutive losses and continuing to record surpluses throughout the late 1980s and early 1990s.

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.
