Cyclone V SOC ARM DMA

Hello, Does the Cortex ARM A9 processor of the Cyclone V SOC FPGA have a hard silicone DMA ? If so, can this DMA be configured to access data from the FPGA through the H2F 128 bit bridge ?

Hi, referring to the Technical Reference DOcument here:

https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/hb/cyclone-v/cv_5v4.pdf

The Cyclone V SOC has an (hardened) DMA-330 instance that connects to the L3 interconnect switch via 64-bit bus. So yes, technically it can be used to access data in the FPGA using H2F bridge, but it will not be efficient since the bandwidth of the bridge is much larger.
