 Mentor Graphics 
Short Desc. : Ethernet IP AHB DMA Ethernet Bridge
Overview :

The M-AHBE™ module from Mentor Graphics provides a DMA bridge between a host system that uses an AMBAAHB™ bus and Ethernet MACs available in the Mentor Graphics Ethernet IP library. Use of the M-AHBE module also requires the
use of a suitable FIFO alongside the Ethernet MAC.
The M-AHBE module interfaces to the host system through 32-bit AHB master
and slave ports. On the MAC side of the module, it has a high-performance
synchronous interface for DMA data transfer to/from the FIFO and a semisynchronous interface for configuring the MAC and the FIFO through their HST
interfaces.


Features : - • AMBA AHB 2.0 compliant master port for payload data transfer
- • AMBA AHB 2.0 compliant slave port for DMA bridge, FIFO, and MAC configuration
- • Synchronous backend interface compatible with Mentor Graphics PE-MCXMAC and PE-MACMII Ethernet MAC cores and associated FIFO modules
- • Asynchronous interface included for addition of Mentor Graphics PE-MSTAT statistics module
- • RAM-free synchronous single-clock domain design
- • 32-bit architecture
- • Linked-list transfer descriptors for minimal software overhead
- • Speed of operation is synthesis dependent only
- • Supports ASIC and FPGA based designs
