In 1999, I led a project to develop the embedded processor design technology with the sponsorship of Korea Ministry of Science and Technology, Korea Ministry of Commerce, Industry and Energy.
In order to catch up the state-of-art technology, I designed the ARM7TDMI compatible processor first.
The behavioral compatibility is verified by developing the instruction set simulator, ARMISS and
prototyping with FPGA.

It was integrated to RamP processor which using the MML (Merged Memory Logic) process.
As the MML process is not developed for the commercial usage, there was no standard cell library. I developed not only the processor but also the standard cell library for it with the technology that I developed for IDEC library.
