3.7.3.3 - processor instruction set - 3.7.3.6 factors affecting cache speed memory

Question 1

what is a processor instruction set

Answer 1

the set of intstructions defined by the manufacturer of a processor that defines what instructions the processor can carry out

Question 2

how is the instrucction set written

Answer 2

it is written in low level languages, and
can only be executed by a processor using the same instruction set it was written for

this is called non portable

Question 3

what does the opcode consisty of

Answer 3

the opcode: a set of bits defining what instruction s to be carried out, such as storing, reading, writing, arithmetic, and logical bit shifts

the operand: the piece ofdata on which the instruction is performed; couldbe memory adress or value

Question 4

adressing mode- what is it and what are the two types

Answer 4

bits in the opcode that dictate how the operand should be interpreted
there are two adressing modes:
diect adress: the value of the operand is a memory adress
immediate adress: the value of the operand is an actual value

Question 5

what are low level languages

Question 6

6 factora affecting processor performance

Answer 6

cache memory -
number of cores -
clock speed -
word length -
data bus width -
address bus width -
