There is a continuous drive for methodologies and approaches of low power design. This is mainly driven by the surge in portable computing. On the other hand, the design of low power systems for different portable applications is not a simple task. This is because of the number of constraints that influence the power consumption of a device. In addition to(More)
In this paper, the authors present implementation of a number of low power FIR filter architectures to design reuse-able, programmable and parameterized soft FIR filter IP Cores and compare their performance in terms of area and power. An overall 22.1% power saving is achieved. The paper provides an analysis of the programmable cores and the impact of their(More)
1. Abstract The paper describes a scheme for the implementation of low power cores for hearing aid applications. Power saving features of the scheme are two fold. The first due to the utilisation of a macro-component framework which allows the rapid assembly of the cores on easy-to-verify hierarchical plug-in basis. The second is due to the system-on-chip(More)
The power consumption of a minimum mean square error (MMSE) multi-carrier CDMA receiver implemented in digital hardware is considered. A low power block based architecture is investigated for the combiner subsystem , and compared with a multiply accumulate circuit approach. Simulations using data consistent with typical performance of a multi-carrier CDMA(More)
The integration of different re-usable IPs (Intellectual Properties) to design SoC (System-on-Chip) devices is widely accepted as the key to achieving higher productivity to meet shorter time-to-market demands. Nevertheless, productivity improvements suffer because the importance of interface definitions and consequently the integration of IPs for the(More)
We approach "nite impulse response (FIR) equalization problem from an H perspective. First, we formulate the calculation of the optimal H performance for a given equalization setting as a semide"nite programming (SDP) problem. H criterion provides a set of FIR equalizers with di!erent optimality properties. Among these, we formulate the calculation of(More)
