An ultra-low power bus
MBus is the next-generation interconnect that enables the millimeter-scale computing class
MBus is a chip-to-chip bus designed for ultra-constrained systems. MBus is a multi-master bus supporting an arbitrary number of nodes, priority arbitration, efficient acknowledgements, and extensible addressing, with only four wires and consuming only 3.5 pJ/bit/chip.
MBus is power-aware, enabling the design of power-oblivious systems. Individual chips can fully power off and MBus will automatically take care of all the tricky details.
MBus was invented and built by a team of researchers at the University of Michigan:
- Pat Pannuto, Ph.D. Student, University of Michigan; Principal Systems Architect, CubeWorks
- Yoonmyung Lee, Assistant Professor, SungKyunKwan University; Co-Founder, CubeWorks
- Ye-Sheng Kuo, Research Fellow, University of Michigan
- ZhiYoong Foo, Co-Founder and CEO, CubeWorks; Research Fellow, University of Michigan
- Benjamin Kempke, Ph.D. Student, University of Michigan; Founder and CEO, Kempke Engineering
- David Blaauw, Professor, University of Michigan; Co-Founder, CubeWorks
- Prabal Dutta, Associate Professor, University of Michigan; Co-Founder, CubeWorks
