+The Agilex5 is a FPGA mounted on Oposa5e_sp. This SoC is composed of hps processor core and FPGA logic zone.
 There are 4 bridges connecting the HPS to the FPGA portion of the Agilex5
-* FPGA-to-HPS (F2H) bridge
+* FPGA-to-HPS (F2H) : 256b ACE5-Lite
-* HPS-to-FPGA (H2F) bridge
+* HPS-to-FPGA (H2F) : 32/64/128 bits AXI4 interface
-* Lightweight HPS-to-FPGA (LWH2F) bridge
+* Lightweight HPS-to-FPGA (LWH2F) : 32 bits AXI4 interface
-* FPGA-to-SDRAM (F2SDRAM) bridge
