The Z8000 was a 16-bit microprocessor introduced by ZiLOG in 1979. A microprocessor incorporates most or all of the functions of a Central processing unit (CPU on a single Integrated Zilog Inc, often seen as ZiLOG (the official company denotation in 1998 through Jun 2007 is a manufacturer of 8-bit, 16-bit, 24-bit The architecture was designed by Bernard Peuto while the logic and physical implementation was done by Masatoshi Shima, assisted by a small group of people. Masatoshi Shima (嶋正利 Shima Masatoshi, born on August 22[[ 943]] in Shizuoka, Japan) was one of the designers of the world's first Microprocessor Z8000 was not Z80-compatible, and although it saw steady use well into the 1990s, it was not very widely used. The Zilog Z80 is an 8-bit Microprocessor designed and sold by Zilog from July 1976 onwards However, the Z16C01 and Z16C02 Serial Communication Controllers still use the Z8000 core.
Although fundamentally a 16-bit architecture, some versions had 7-bit, segment registers that extended the address space to 8 megabytes. The term architecture (from Greek αρχιτεκτονικήarchitektoniki) can be used to mean a process a profession or documentation x86 memory segmentation refers to the implementation of Memory segmentation on the X86 architecture.
The register set consisted of sixteen 16-bit registers, and there were instructions that could use them as 8-bit, 16-bit, 32-bit, and 64-bit registers. In Computer architecture, a processor register is a small amount of storage available on the CPU whose contents can be accessed more quickly than storage Eight-bit CPUs normally use an 8-bit data bus and a 16-bit address bus which means that their Address space is limited to 64 KBs This is not a "natural The range of Integer values that can be stored in 32 bits is 0 through 4294967295 or −2147483648 through 2147483647 using Two's complement encoding '64-bit' CPUs have existed in Supercomputers since the 1960s and in RISC -based workstations and servers since the early 1990s. The register set was completely orthogonal, with register 15 conventionally designated as stack pointer, and register 14 for stack segment. In Mathematics, two Vectors are orthogonal if they are Perpendicular, i In Computer science, a stack is an Abstract data type and Data structure based on the principle of Last In First Out (LIFO
Like the Z80, the Z8000 included built-in DRAM refresh circuitry. 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. See also X86 assembly language The generic term x86 refers to the most commercially successful Instruction set architecture in the history of Personal
One notable use of the Z8000 series was by Namco in the design of its famous Pole Position series of racing videogames. is an amusement company based in Japan, best known overseas for Video games development Pole Position is a racing Video game released in 1982 by Namco. Two Z8002's (small-memory versions of the Z8000) were incorporated into the design.
The reported inclusion of the device within military designs (source:TechWeb ), perhaps provides an explanation for the continued survival of the Z8000 today, in the shape of the Z16C01/02 Serial Communication Controllers (Zilog SCC). A military is an Organization authorized by its Nation to use force usually including use of Weapons in defending its Country (or by attacking The Zilog Serial Communications Controller or Zilog SCC was introduced in the early 1980s and provided the ability to do both standard UART style serial communications Indeed, an active order code and datasheet may still be located upon the ZiLOG website.
The Zilog Z80000 was a 32-bit follow-on design. The Z80000 was Zilog 's 32-bit processor from 1986, an expansion of its 16-bit predecessor the Zilog Z8000.
