How to organize data stream through AMBA bus between FPGA and HPS (with Linux)?

Hi,

First read Cyclone V SoC device handbook especially on HPS-FPGA bridges.

Then examine a simpler Examples in the installed EDS_SOC (\embedded\examples). Use LW_HPS-FPGA bridge and GPIO Linux example.

A more complex design is the VipDemo for Arrow SoCKit (run linux, and use bridges between FPGA-HPS portions).

There are full descriptions about functions under your installed EDS_SOC directory:

SoCAL: as abstraction layer for SoC (similar to Nios's HAL)

HWLib: Hardware Libraries

Altera HWLib and SOCAL API pages:

<altera_installation_directory>/embedded/ip/altera/hps/altera_hps/doc/hwmgr/html/index.html

<altera_installation_directory>/embedded/ip/altera/hps/altera_hps/doc/socal/html/index.html

I hope these helps to start your work.

best regards
