3.17. 64-bit to 32-bit funnel

The AHB funnel, Funnel, is a data path multiplexor block used to convert a 64-bit data bus to 32-bit data bus in AMBA systems. This module is used where the 32-bit slaves are to be accessed by a 64-bit master using transfers of word size or smaller. Figure 3.41 shows the signal interface of the funnel module.
