Mitsubishi Electric Corp has developed an operating system, which it is calling MR770, for its 16-bit Tron microcontroller: the operating system is claimed to improve processing speed fourfold, and Mitsubishi will incorporate the chip in its MEPLS7700 16-bit microcomputer which it will start delivering in November: the MR7700 is the first version of Tron to implement the I-Tron specifications – I-Tron is the real-time industrial variant; task switching time is 32 microseconds, and the overall speed of the part with the operating system is about four times faster than Mitsubishi’s 32-bit microprocessor; the operating system has 35 modules, including functions such as time management, input output drivers and interrupt management, and the microcontrollers are expected to find their embedded way into anything from industrial robots to facsimiles machines.
