More about memory addresses
Memory
addresses
are always written in base 16 or
hexadecimal
notation. Unlike the ten digits of the decimal system (0-9),
hexadecimal uses sixteen digits (0-9 and A-F, where A=10, B=11,
C=12 and so on up to F=15).
Hexadecimal numbers are denoted either by the suffix “h” or by the
prefix “0x”. The final digit of a five-digit memory address is often
omitted, so C8000h may be written as C800h.
Because
amounts
of memory are usually stated as kilobytes (Kbytes)
rather than in hexadecimal notation, the following conversion table
may be helpful:
4 Kbytes = 1000h
32 Kbytes = 8000h
8 Kbytes = 2000h
64 Kbytes = 10000h
16 Kbytes = 4000h
128 Kbytes = 20000h
