A program consisting of 204 1.5
instructions is executing on
a simple processor. Each
instruction takes 4 cycles to
complete, with a clock rate
of 546 KHz. How long will
it take to execute the
program? Give your
answer in units of
milliseconds with at least 1
decimal place of precision.
A program consisting of 225 81.8
instructions is executing on
a simple processor. Each
instruction takes 4 cycles to
complete, with a clock rate
of 11 MHz. How long will it
take to execute the
program? Give your answer
in units of microseconds
with at least 1
decimal place of precision
If two computers made by Architecture
different companies have
the same machine
language, that means they
have the same:
A program consisting of 323 3.8
instructions is executing on
a simple processor. Each
instruction takes 4 cycles to
complete, with a clock rate
of 339 KHz. How long will
it take to execute the
program? Give your
answer in units of
milliseconds with at least 1
decimal place of precision.
