HES Proto-AXI Host Interface

Aldec HES™ Proto-AXI is a host interface module that provides:


Aldec provides two types of Proto-AXI interfaces:


They are compatible with each other at the hardware level (the same Proto-AXI IP) and software level (the same software API).




Max. Throughput Min. Round-trip message latency
  Proto-AXI PC Host 2000 MB/s 33 us
  Proto-AXI Embedded 1245 MB/s 15 us

 Benchmarking data for HES-US-440 board

  • Max throughout measured using burst transfers
  • Min Round-trip message latency measured using 32-bit datagrams


Both types also provide an easy access to all kinds of on-board memories without the need of configuring custom memory controllers. These memories are accessible at pre-configured address ranges of the AMBA AXI subsystem. Proto-AXI allows connecting multiple user design modules that can be both Master and Slave memory mapped AXI devices. Moreover, all these devices can transfer data with one another thanks to the AXI interconnect contained in Proto-AXI IP. The memory map of Proto-AXI can be customized thanks to configurable memory remappers included in the Proto-AXI IP. There are also GPI/GPIO lanes in the Proto-AXI IP used to realize non-standard interfaces or to transfer status or configuration data directly without using AXI protocol. An example of the Proto-AXI IP configuration on the HES-US-440 board is shown in the following block diagram.
