LeWiz provides a range of Ethernet MAC controllers from 100Gbps to 10Mbps for use in space, defense, and ultra-low latency applications. This datasheet is for the 100G/50G/25G/10Gbps Ethernet MAC IP core.
On the internal user logic side, it has 3 interfaces. Two are FIFO interfaces. One FIFO interface is used for transmit purposes (including data and control signals). The other is used for receiving purposes. A third interface is also available for interface to internal registers. This is the simple advanced peripheral bus interface standard (address, data, read/write control).
For ultra-low latency applications, a bond-out option can be provided to directly receive data from internal of the MAC by-passing other logics.
For security applications, a split interface option can be provided to enable the user to implement data filtering, deep packet inspection and other functions.
For space applications (option), each core can be made available with built-in full or partial tri-modular redundancy.
For AXI based internal bus system, an option can be provided to bond out as AXI-stream interface to the user. The design can be connected directly to DMA or smart, descriptor-based DMA functions (as shown above). FIFO interface and other interfaces in the MAC are 256/64-bit at 156MHz Ethernet clock rate. User clock or under internal bus can be designed to run at different clock (or much higher speed) than the MAC internal clock.
Sustain full 100G line rate performance on both the receiving and transmitting side. Best performance even at smallest Ethernet packet size
If used in conjunction with LeWiz smart, descriptor-based DMA (option), the DMA uses command descriptors constructed by the device driver software to enable the MAC to transmit and receive without requiring CPU assistance. DMA will fetch data for the MAC on transmit and will place data into system memory for the software stack to process on receiving side.
Driver Support is available for Linux (Windows and others available based on customer request)
FPGA support currently available for Stratix V. Others available based on customer request.
LeWiz also provides customization and design services to assist customers if required.
