    • Computing Euclidean Distances is a very important operation in digital communication, especially in the case of trellis coded modulation, where it is used numerously. This paper shows that a substantial reduction in complexity can be achieved in hardware processing elements for computing Euclidean Distances. A reduction in complexity down to 39% is shown compared to traditional designs. The paper also shows that the optimized design can be done completely ripple free, which leads to a reduction of the critical path to far more than half. The reduction in complexity leads to a reduction in power consumption. The ripple free design also leads to lower power consumption for two reasons: the rippling in itself leads to unnecessary glitches, which costs power and the shorter critical path enables a lower supply voltage, which reduces the power consumption as well. © 2011 IEEE.

  • A VLSI Implementation of Logarithmic and Exponential Functions Using a Novel Parabolic Synthesis Methodology Compared to the CORDIC Algorithm
  • 2011
  • Ingår i: 2011 20th European Conference on Circuit Theory and Design (ECCTD). - New York : Institute of Electrical and Electronics Engineers (IEEE). - 9781457706189
  • Konferensbidrag (refereegranskat)abstract
    • High performance implementations of unary functions are important in many applications e.g. in the wireless communication area. This paper shows the development and VLSI implementation of unary functions like the logarithmic and exponential function, by using anovel approximation methodology based on parabolic synthesis, which is compared to the well known CORDIC algorithm. Both designs are synthesized and implemented on an FPGA and as an ASIC. The results of such implementations are compared with metrics such as performance and area. The performance in the parabolic architecture is shown to exceed the CORDIC architecture by a factor 4.2, in a 65 nm Standard-VT ASIC implementation. © 2011 IEEE.
