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
  • IP core clock is independent of line rate and can be asynchronous to both the SerDes and application clocks
  • Support for SerDes with parallel interfaces of multiple bit widths
  • 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

UFS Goes Mainstream

UniversalFlash Storage (UFS) was created for mobile applications and computer systems requiring high performance and low power consumption. These systems typically use embedded Flash based on the JEDEC standard eMMC. UFS was defined by JEDEC as the evolutionary replacement for eMMC offering significantly higher memory bandwidth. The standard builds on existing standards such as the SCSI command set, the MIPI Alliance M-PHY and UniPro as well as eMMC form factors to simplify adoption and development.

Design IP Faster: Introducing the C~ High-Level Language

In this paper, we introduce a new high-level, dataflow programming language called C~ (“C flow”) that further increases productivity by raising the level of abstraction from behavioral descriptions, while overcoming the limitations of C for hardware design. We present the syntax and semantics of this language, and the framework that provides hardware and software code generation. This paper illustrates the benefits of using C~ for hardware design of a IEEE 802.3 MAC, synthesized for FPGA and for 90nm CMOS technology.

These systems typically use embedded Flash based on the JEDEC standard eMMC. UFS was defined by JEDEC as the evolutionary replacement for eMMC offering significantly higher memory bandwidth. The standard builds on existing standards such as the SCSI command set, the MIPI Alliance M-PHY and UniProSM as well as eMMC form factors to simplify adoption and development.

Can MIPI and MDDI Co-Exist?

Since MIPI and MDDI standards both target interfaces to cameras and displays on mobile devices, are two separate standards really needed?
