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
completed. Just complete the design and program the
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.
