چکیده
This paper presents a Field-Programmable Digital Filter (FPDF) IC that employs carry-propagation-free redundant arithmetic algorithms for faster computation and multiplevalued current-mode circuit technology for high-density lowpower implementation. The original contribution of this paper is to evaluate, through actual chip fabrication, the potential impact of multiple-valued current-mode circuit technology on the reduction of hardware complexity required for DSP-oriented programmable ICs. The prototype FPDF fabrication with 0.6μm CMOS technology demonstrates that the chip area and power consumption can be reduced to 41% and 71%, respectively, compared with the standard binary logic implementation. key words: multiple-valued logic, signal processor, FPGAs, FIR filters

متن کاملLook-up Tables (LUTs) for Multiple-Valued, Combinational Logic
The use of Look-Up Tables (LUTs) is extended from binary to multiple-valued logic (MVL) circuits. A multiple-valued LUT can be implemented using both current-mode and voltage-mode techniques, reducing the transistor count to half compared to that of a binary implementation. Two main applications for multiple-valued LUTs are multiple-valued FPGAs and intelligent memories. An FPGA uses a LUT as a...
