M80C186EB EXECUTION TIMINGS
A determination of M80C186EB program execution
timing must consider the bus cycles necessary to
prefetch instructions as well as the number of exe-
cution unit cycles necessary to execute instructions.
The following instruction timings represent the
mini-
mum
execution time in clock cycles for each instruc-
tion. The timings given are based on the following
assumptions:
#
The opcode, along with any data or displacement
required for execution of a particular instruction,
has been prefetched and resides in the queue at
the time it is needed.
#
No wait states or bus HOLDs occur.
#
All word-data is located on even-address bound-
aries.
All jumps and calls include the time required to fetch
the opcode of the next instruction at the destination
address.
All instructions which involve memory accesses can
require one or two additional clocks above the mini-
mum timings shown due to the asynchronous hand-
shake between the bus interface unit (BIU) and exe-
cution unit.
With a 16-bit BIU, the M80C186EB has sufficient bus
performance to ensure that an adequate number of
prefetched bytes will reside in the queue most of the
time. Therefore, actual program execution time will
not be substantially greater than that derived from
adding the instruction timings shown.
