Operand bus
performance
(cont)
Waited
cycle
Waited cycles for
operand fetch
(READ)
WOR
The number of wait cycles by a
memory access (read) of an
operand.
Waited cycles for
operand fetch
(WRITE)
WOW
The number of wait cycles by a
memory access (write) of an
operand.
Waited cycles for
operand cache miss
(READ)
WCMR
The number of wait cycles by
an operand cache miss (read)
(however, the number of wait
cycles of cache FIII is included
due to contention).
Waited cycles for
operand cache miss
(WRITE)
WCMW
The number of wait cycles by
an operand cache miss (write).
System bus
performance
(only available
for Ch3 and
Ch4)
System bus
Number of requests
RQ
The number of valid bus cycles
(cells) is counted by the
system bus clock.
Number
of
responses
RS
The number of valid bus cycles
(cells) is counted by the
system bus clock.
Waited cycles for
request
WRQ
The cycles for an issued
request (req), that no
acceptance signal (gnt) is
issued to, are counted by the
system bus clock.
Even if the waits are issued
simultaneously for multiple
requests, they are counted as
1.
Waited cycles for
response
WRS
The cycles for an issued
response (r_req), that no
acceptance signal (r_gnt) is
issued to, are counted by the
system bus clock.
Even if the waits are issued
simultaneously for multiple
requests, they are counted as
1.
