Appendix 1.5
Operation Processing Time of LCPU
The processing time for the individual instructions are shown in the table on the following pages.
Operation processing times can vary substantially depending on the nature of the sources and destinations of the instructions,
and the values contained in the following tables should therefore be taken as a set of general guidelines to processing time
rather than as being strictly accurate.
Appendix 1.5.1
Subset instruction processing time
The following describes the subset instruction processing time.
(1) The processing time shown in "(1) Subset instruction processing time table" applies when the device used in an
instruction meets the device condition for subset processing (For device condition triggering subset processing, refer
to Page 102, Section 3.5.1).
(2) When using a file resister (R, ZR), extended data register (D), and extended link register (W), add the processing time
shown in (2) to that of the instruction.
(3) When using an F,T(ST),C device with an OUT/SET/RST instruction, add the processing time for each instruction, with
reference to the adding time in (3).
(4) Since the processing time of an instruction varies depending on that of the cash function, both the minimum and
maximum values are described in the table.
