Instruction bus

Instruction
(cont)
Number of
instruction cache
miss
ICM The number of cache misses
by an instruction cache
access (the number of
accesses to the outside of the
CPU core due to a cache
miss).
Number of internal-
RAM access for
instruction fetch (XY-
RAM or L memory)
XL The number of accesses for
the XY memory in the
SH7343 during memory
accesses of the opcode.
Operand bus
performance
Access
count
Number of memory
access for operand
fetch (READ)
MR The number of memory
accesses by an operand read
(equal to loading on the
operand bus).
Accesses by the PREF
instruction or canceled
accesses are not included.
Number of memory
access for operand
fetch (WRITE)
MW The number of memory
accesses by an operand write
(equal to storing memory on
the operand bus).
Canceled accesses are not
included.
Number of operand
cache access
(READ)
CR The number of operand-
cache reads during memory
access (read) of an operand.
Number of operand
cache access
(WRITE)
CW The number of operand-
cache reads during memory
access (write) of an operand.
Number of internal-
RAM access for
operand fetch
(READ) (XY-RAM or
L memory)
XLR The number of accesses to
XY memory in the SH7343
during memory access (read)
of an operand.
(Accesses via the XY bus and
the operand bus are included.
When MOVX and MOVY are
executed simultaneously, it
increments one count
regardless of the read or
write.)
