A large number of system-on-a-chip (SoC) designs utilize fixed-point computation units due to their simplicity and efficiency over floating-point functional units. The selection of variable widths for fixed-point computing is critical in determining the computation accuracy and hardware complexity of these SoCs. In this paper, we present an optimization procedure for a wireless receiver. Extensive...
Rotary clock is a resonant clocking technique that delivers on-chip clock signal distribution with very low power dissipation. Since it can only generate clock signals with multiple phases that are spatially distributed, rotary clock is often considered not applicable to industrial very large scale integration (VLSI) designs. This paper presents the first rotary-clock-based nontrivial digital circuit...
In this paper, we present a systems-on-chip (SoC) design for the 3G code division multiple access (CDMA) receiver using the multiple-input multiple-output (MIMO) technique. Our chip integrates the entire digital signal processing part of the receiver. Furthermore, the proposed design can be reconfigured in real-time to handle different modulation schemes based on the signal-to-noise ratio, resulting...
