BoW PHY 2.1
By Kevin Donnelly (Eliyan), Kash Johal (Yorchip) and Shahab Ardalan (Enosemi)
The BoW working group is focused on extensions to the standard to expand its applications.
BoW.Optical. The co-integration of optical and electrical chiplet with a BoW interface not only reduces power consumption by utilizing direct-drive interfaces but also enables low-latency, distance-invariant I/O for any system, paving the way for the next generation of photonic-enabled systems.
BoW.Memory. With the growing needs of HPC and AI systems for Memory and low latency access, the “memory wall” is the limiting factor for performance. BoW.Memory will show how the BoW interface can be extended to improve BW/mm and be used to directly connect ASICs to Memory
BoW support for IoT and Wirebond. Key specs for this PHY are - low area, power, simplicity and flexibility. The goal is to support data rates of 1GHz down to 100Mhz. Wirebond devices and older technology nodes can now mix and match with more advanced BoW chiplets.
