7.3.2 HPDMA Use Models

This section explains the use models and gives directions for using HPDMA in an application. The SmartFusion 2 soft memory controller fabric interface controller (SMC_FIC) is used to access external bulk memories other than DDR through the FPGA fabric. The SMC_FIC can be used with a soft memory controller for the MSS to access memories such as SDRAM, Flash, and SRAM. MSS masters communicate with the SMC_FIC through an MSS DDR bridge present in the MSS. Fore more information on SMC_FIC, see UG0446: SmartFusion2 and IGLOO2 FPGA High Speed DDR Interfaces User Guide.
