AHB-to-APBH Bridge with DMA (APBH-Bridge-DMA)
6.1 AHB-to-APBH Bridge Overview
The AHB-to-APBH bridge provides the i.MX28 with an inexpensive peripheral attachment
bus running on the AHB's HCLK. (The H in APBH denotes that the APBH is synchronous
to HCLK, as compared to APBX, which runs on the crystal-derived XCLK.)
As shown in the following figure, the AHB-to-APBH bridge includes the AHB-to-APB
PIO bridge for a memory-mapped I/O to the APB devices, as well as a central DMA facility
for devices on this bus and a vectored interrupt controller for the ARM926 core. Each one
of the APB peripherals, including the vectored interrupt controller, is documented in their
own chapters elsewhere in this document.
