real-time OS
Caution When purchasing the RX78K/IV, fill out the necessary forms and conclude a contract with NEC.
Remark
S
and
RX78K4-
The RX78K/IV is intended to realize multi-task environments in areas where real-time features are
required.
This OS can improve the performance of the entire system by allocating the idle time of the CPU to
the other processing.
The RX78K/IV supplies 31 system calls conforming to the ITRON specifications. It also supplies a
tool (configurator) that is used to create the nucleus of the RX78K/IV and several information tables.
This OS is used in combination with the assembler package (RA78K4) and device file (DF784026)
optionally available.
Part number:
