what is the difference between a microprocessor and a microcontroller?
Answer - microprocessor- computer system with i/o and memory
microcontroller - can do computing, but most functions are built into it, a to do
io capabilities built into it, less powerful
Explain Connecting I/Os to CPU using bus, 2^x adress line where x is the
number of adresses i the number of location Answer -
**what are some of the pieces inside of a cpu? what does eahc one do?
Answer - ALU = number cruncing and computation
register= memory location in CPU, uses values in register for computation,
temporary
instruction decoder- translates commands and decipher what intructions
should do,
Program counter = tells you when to move on from that program and move to
next command, keeps track of intruction, point adress to next command to be
executed, which instruction we are on
FLIP
i/o device 17, load in a
copy a and put in b
take whatever is adress 7 and put into a
put a+b into A
put a in memory location Answer - Try to explain what this psuedo code means
, what are the meanings of these operation codes
000
001
010
011
100
101
110
111
and how do they work? Answer -
***FLIP
program counter gives first adress to execute the program, data bus reads in
the first command located in 0 to the instruction decoder (31) , instruction
decoder decodes the instruciton to read I/O 17 and to place it in register A
adress bus gets 1 from the program counter, goes to 1 command locations,
data bus reads command into instruction decoder, decoder deciphers to copy
what is in a into b, Answer - explain how this computer and it's components
work
read vs write with I/O Answer - read I/O into the CPU (input)
write from CPU into I/O (output)
memory organization description Answer -
what is the relationship between the CPU, memory, and I/O Answer -
