Altera claims fastest, largest PLDs with up to 40% speed improvement News & Analysis 2/11/2002 Post a comment SAN JOSE -- Altera Corp. today announced it has developed the industry's fastest and largest programmable logic devices with the launch of a new series, called Stratix, which offers up to 10 megabits of RAM and 114,140 logic elements on a chip. The new series will offer a 40% speed improvement over the company's previous generation of PLDs, said Altera.
21st Century Slide Rules with Logarithmic Arithmetic Design How-To 2/6/2002 Post a comment Using the Logarithmic Number System (LNS) as an alternative to fixed- and floating-point arithmetic reduces multiplication, division, and square root implementation while improving power and area. Mark G. Arnold of the University of Manchester discusses three forms of LNS along with a Verilog implementation of a linear-Lagrange interpolator targeted for an FPGA.
FPGA-Based FIR Filters using Distributed Arithmetic Design How-To 2/4/2002 Post a comment You employ Distributed Arithmetic techniques to save resources in multiply-and-accumulate (MAC) structures implementing DSP functions. M. Martinez-Peiro and fellow authors from the Universidad Politecnica de Valencia, Spain, describe three types of FPGA-based FIR filters they designed using DA methodology, along with a comparison of filter performance.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
