AXI5 to/from AXI4 Bridge
The AXI-BRG enables communication between an AXI5 interface and an AXI4 interface.
Overview
The AXI-BRG enables communication between an AXI5 interface and an AXI4 interface. The core is designed for minimal latency and area, with its main functions including calculation of check signals from the AXI4 interface and parity checking of signals sent by the AXI5 interface.
The bridge also adds WAKEUP and USER inputs/outputs and offers configuration options to suit different applications. The core provides different error handling options for each signal, including the option to either terminate or propagate the transmission upon error detection.
The AXI-BRG implements a set of maskable interrupt lines for each AXI parity signal independently. The bridges also support both AXI and AXI-Lite protocols through synthesis configuration.
The core includes two bridges: a 4-to-5 bridge that connects an AXI4 Master with an AXI5 Subordinate, and a 5-to-4 bridge that connects an AXI5 Master with an AXI4 Subordinate.
Key features
- Calculation of parity check signals to be sent to the AXI5 interface.
- Parity checking for check signals sent from the AXI5 interface.
- Addition of WAKEUP and channel USER signal inputs/outputs.
- Registered signals on the AXI5 interface.
- Support for both AXI and AXI-Lite through synthesis configuration.
- Bus width options:
- 2N data bits, where 2 < N < 11.
- Configurable address width.
- Configurable number of user bits.
- Parity error output line per AXI signal.
- Configurable error behavior per AXI signal through mode input:
- Terminate transfer and disable core.
- Continue transfer after error reporting.
- Maskable interrupt lines for parity errors per AXI signal.
