How to Use FPGAs for Speed & Flexibility – 8400650

Benefits of FPGA Modules Derived from their Speed and Flexibility – You Can’t Do More for Less

Learn about FPGA-based system design for embedded computing I/O signal processing applications.

This white paper discusses how Advanced Xilinx Virtex and Altera Stratix FPGAs make use of multiple digital clock managers and simultaneous parallel execution to rapidly compute a set of integrated processes including:

  • FFT
  • FIFO Management
  • Logic Sequencing
  • DDR Control
  • and More

FPGA I/O Flexibility

The external world has a wide mix of I/O interfaces. Any FPGA module to be used must meet that interface. Acromag started with and developed a large family of FPGA modules. The IP-EP20x family of FPGA modules has a fixed I/O interface with several options including CMOS/TTL, RS422/485, mixtures of these, and LVDS.
The larger FPGA modules in the Virtex-4 and Virtex-5 family (PMC and XMC) offer rear I/O configurable within the FPGA via the constraints file to accommodate LVCMOS, LVTTL, and LVDS for 64 total connection points. Realizing that the need for I/O flexibility is paramount to a successful FPGA application, Acromag proceeded by providing additional I/O flexibility at the front I/O using the AXM mezzanine module concept. These AXM modules provide for wide flexibility with standard
offerings of: TTL, RS422/485, LVDS, and 105MHz A/D. Custom modules for an open specification can also be designed by you or by Acromag to meet your specification.

So, how fast can an FPGA module process data?
