High-bandwidth 28nm FPGA for increased bandwidth in broadcast and communications systems
Published: 29 October 2012 - Michelle Winny
Transceiver technology from Altera Corporation has been developed that has the capability to deliver better core performance of more than two speed grades.
The technology is a response to the growing demand for more bandwidth in communications and broadcast applications. The company’s Arria V GZ FPGAs feature 36 backplane-capable transceivers, can operate at speeds of up to 12.5Gbps and can enable of a variety of protocols.
In addition to this, the devices feature four separate DDR3 DIMM interfaces at 72 bits wide, operating at 1600Mbps. The mix of transceivers, fabric performance and quantity of available off-chip memory interfaces in these devices is claimed by the company to represent the only type of device available for midrange FPGAs.
“Customers face many challenges when designing high-performance systems, including the need to balance power and performance while increasing bandwidth to off-chip memory,” said Patrick Dorsey, senior director of component product marketing at Altera Corporation.
“The Arria V GZ variant provides both the high-speed serial transceivers and the external memory capability that designers need to build today’s bandwidth-hungry data processing systems.”
Additional features of these devices include hardened PCI Express Gen3 protocol stacks along with soft intellectual property (IP)-based memory controllers which allow for maximum flexibility.
Further to this, the devices feature the most digital signal processing (DSP) in a midrange FPGA for high integration.
They are also designed with anti-tamper features including enhanced advanced encryption standard (AES) and easy-to-use on-board and off-board key programming.
