A massively popular and influential 8-bit microprocessor originally released in 1974. Among other uses, it powered the Altair 8800 and served as the basis for the Z80 and the LR35902.
The 8080 has the following registers:
15…8 | 7…0 | |
---|---|---|
A | F | PSW |
B | C | B |
D | E | D |
H | L | H |
SP | ||
PC |
Flags register:
7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
---|---|---|---|---|---|---|---|
S | Z | 0 | A | 0 | P | 1 | C |
Like its descendants, the 8080 stores addresses in little-endian format and has a stack that grows downward.
