Introduction
The Virtex
-E Extended Memory (Virtex-EM) family of
FPGAs is an extension of the highly successful Virtex-E
family architecture. The Virtex-EM family (devices shown in
Table 1
) includes all of the features of Virtex-E, plus addi-
tional block RAM, useful for applications such as network
switches and high-performance video graphic systems.
Xilinx developed the Virtex-EM product family to enable
customers to design systems requiring high memory band-
width, such as 160 Gb/s network switches. Unlike traditional
ASIC devices, this family also supports fast time-to-market
delivery, because the development engineering is already
device. There is no NRE, no silicon production cycles, and no
additional delays for design re-work. In addition, designers
can update the design over a network at any time, providing
product upgrades or updates to customers even sooner.
The Virtex-EM family is the result of more than fifteen years
of FPGA design experience. Xilinx has a history of support-
ing customer applications by providing the highest level of
logic, RAM, and features available in the industry. The Vir-
tex-EM family, first FPGAs to deploy copper interconnect,
offers the performance and high memory bandwidth for
advanced system integration without the initial investment,
long development cycles, and inventory risk expected in tra-
ditional ASIC development.
