niksiz kardeşim
bikaç site buldum vaktim yok şuanda ama mikro işlemcinin en fazla kılıf yapısı fln değişiktir
ancak mantık aynı oluyo biliyosun
sana tam olarak nesi lazım bu işlemcinin
mikroişlemciyle aram iyi yardımcı olabilirim istersen

ARCHITECTURE SUMMARY: Zilog Z-80
The Z-80 was introduced by the Zilog Corp. in the late 1970's as an enhanced version of the Intel 8080 microprocessor chip. The Z-80 provided additional instructions, higher speed, and required fewer support chips. The Z-80 may be the most widely used 8-bit microprocessor. So great was the dominance of the 8080, though, that the Z-80 is usually used as a direct equivalent, with its extra instructions ignored.
Addressing unit: 8-bit byte
Address space: 16 bits (65,536 bytes)
Data path: 8 bits and 16 bits
Typical instruction time: 1-2 µs
Typical cost: $10 (microprocessor only)
$1000 & up (complete microcomputer)
SYSTEM ORGANIZATION:
(typical)
CPU MEM I/O I/O

------------------------ ...
BUS
CPU STRUCTURE:
7 general purpose 8-bit registers, called A,B,C,D,E, H,L. The pairs B-C, D-E, and H-L can be loaded and stored as 16-bit units. H-L is normally used for register addressing.
8-bit PSW, including flags for zero value, negative value, carry, auxiliary (4-bit) carry, "borrow", parity/overflow.
A set of BACKUP registers for the 7 GP registers and PSW, which can be swapped with them.
2 16-bit index registers; 16-bit stack pointer; 16-bit program counter
Misc: IR, MAR, MDR (inaccessible); 8-bit interrupt vector register; 8-bit memory refresh register
DATA TYPES:
bit sequence: 8-bit, 16-bit
numeric:
integer, signed (2's compl): 8-bit
integer, packed BCD decimal: 8-bit
logical: 1-bit, 8-bit
character: 8-bit; strings to 256 bytes
stacks: without limit control
ADDRESSING MODES:
Immediate; Direct; Register (Explicit,Implied); Indexed (8-bit offset); Relative (branching only)
INSTRUCTION SET:
Notable aspects: Decimal instructions; swap instructions; block move; register addressing; Subr. return address saved in memory stack.
NOTES:
Limited vectored interrupt available. Programmed input & output.
Typical peripherals: Video terminal, printer, tape cassette, floppy disk, communication equipment, special hardware.
