In 2014 CHI (Coherent Hub Interface) was introduced for cache coherency and improved congestion handling.The host processor typical- ly connects to the peripheral using a standard bus interface such as AMBA AXI4 or AXI4-Lite.
AXI was first introduced with the third generation of AMBA, as AXI3, in 1996.Bridge. This module implements a bridge/adapter which can be used to convert AXI-4 transactions into AXI4-LiteThe board features multiple connectivity interfaces. 7000 FPGA with VIVADO in VHDL Create Custom AXI-4 Slave Led Controller IP with VIVADO IPI in VHDL.Transactions. This bridge acts as a slave on the AXI4Interface and as a master on an AXI4-Lite interface. In 2010 came AXI4 Lite and AXI4 Stream along with ACE Lite. (ACE stands for AXI Coherency Extensions.) Those were much more suitable as the backbone protocol interfaces for FPGAs and networking.
Axi4 Lite Interface Generator Inserts A
TheAuto setting means that the code generator inserts a certainNumber of pipelines for the AXI4 slave ports depending on the number of ports and theSynthesis tool that you specify. For example, an AX4 slave portTo pipeline register ratio of 20 means that onePipeline register is inserted for every 20 AXI slave registers. This setting indicates how many AXI4 slaveRegisters a pipeline register is inserted for. The default value ofThis setting is auto.
