Overview

The multi-channel, multi-speed Ethernet universal media access control (MAC) and physical coding sublayer IP (UMAC) is fully configurable and programmable to support “any rate on any channel” (800G/600G/400G/200G/100G/50G/25G/10G/1G). It uses a novel time-sliced architecture that affords maximum density for high port count applications while maintaining industry-leading latencies that are optimized for data center applications.

In addition to being compliant with the IEEE 802.3bs, IEEE 802.3-2012, 25G/50G Ethernet Consortium, IEEE 802.3by, and OIF Flex-E Standards, CoMira also offers non-standard and application-driven protocols and modes of operation that allow us to tailor each IP configuration to a customer’s specific needs. This, in turn, lets them better differentiate their own end products.

The encoding and security IPs are available as seamless configuration add-on options that can be included with the UMAC IP.

Key features

Programmable application-side FIFO sizes (or complete bypass ) on TX, RX or both for easy integration with application logic
Packing and unpacking logic for application to internal data path matching
Supports line rate with minimum IFG
Memory-based statistics counter implementation for Area/gate savings

Virtual Lane Mapping (VLM) support of multiple SerDes
Support for flow control using either standard or priority pause frames
Jumbo frame support
Per Frame IFG on transmit for frame pacing
Per frame configurable preamble on transmit
Per frame preamble extraction on receive
Custom preamble length
Frame time stamping on both transmit and receive
Optional custom header insertion
Per frame CRC control/CRC stomping
Configurable statistics counters from 32 to 90+ per channel depending on application requirements
