 Posted: Fri Apr 13, 2007 3:42 pm Post subject: Cswitch - Configurable Switch Array for highspeed networking |
 |
|
The Cswitch Corporation from Santa Clara offers a very interesting chip specifically designed to provide all necessary switch components in a configurable - FPGA like - manner.
| Quote: | With all the Configurable Switch Array has to offer,
designers can now replace both costly and timeconsuming ASICs, and slow, inadequate FPGAs with a chip that offers the best of both. |
This "2 GHz switch specific FPGA" for networking provides the following resources internally:
- Configurable MACs:
- 10/100/1000 Mbps Ethernet
- 10 Gbps Ethernet
- 1/2/4 Gbps Fibre Channel
- SERDES:
- 4 Lane 1–6.4 Gbps full duplex
- Serial Links for 1 Gbps Ethernet,
- 10 Gbps XAUI, Fibre Channel
- PCI Express
Programmable Logic Blocks (PLBs):
- Up to 500 MHz FPGA Logic (4 Input LUTs with 64 Bits of Distributed RAM)
- Dual Port RAMs:
- 1 GHz SRAMs, up to 2.2 Mb
- PacketParser™ Frame Parser Blocks:
- 800 MHz Nanoprocessors for parsing layer 2–4 protocols such as Ethernet, TCP/IP, MPLS, and Fibre Channel
- Reconfigurable Arithmetic Units (RAUs):
- 1 GHz Reconfigurable Arithmetic Units for packet editing (CRC, hashing, checksums, etc.)
- Reconfigurable CAMs (RCAMs):
- 1 GHz Reconfigurable CAMs for packet classification and filtering
- Single Port RAM:
- 1 GHz SRAM storage,up to 16 Mb
The chip is suitable for up to 100 Gbit networking applications. Internally, it relies on a 20-bit wide 2 GHz bus with Cswitchs own dataCrossconnect™ intersections. | Quote: | It’s the first configurable solution to deliver bandwidth at 40 to 100 Gbps for a range of applications, making it capable of moving up to 6 TBps of packets at speeds of up to 2 GHz. To handle editing tasks, the chip packs a rich
assortment of Frame Header Parsers, Arithmetic Units, and RCAMs to edit and classify packets at 1 GHz speeds. For storing packets, the chip includes over 18 Mb of on-chip memory, as well as support for the latest high-speed memories, such as DDR2, RLDRAM2, and QDR2. |
