Advanced packaging (3D and chiplets)
What is the data transfer capacity that can be secured per unit length of chip edge called, emphasized as a performance metric for chiplet interconnects?
- AFIT
- BBandwidth density (transfer rate per unit length of chip edge)
- CProcess capability index
Show answer and explanation
Answer: B. Bandwidth density (transfer rate per unit length of chip edge)
Chiplets are usually connected through terminals arranged along their edges, so how much data can be transferred per 1 mm of edge length (bandwidth density) is an important metric. The energy needed to send one bit is also emphasized.
