MP6

The MP6 was the microprocessor developed by the Rise Technology. Their intention was to compete with the Intel Pentium. They hardly spent 5 years in developing the processor. It was in 1998 that the Rise Technologies MP6 dint got clicked in the market and the quited the market silently.
The Silicon Integrated Systems later licensed the MP6 technology and so they used it in the SiS550, a system-on-a-chip that integrated the MP6 CPU sound and video on a single chip. The SiS550 was then used in some of the DVD players.
