A RISC-V ISA Extension For Ultra-Low Power IoT Wireless Signal Processing


This work presents an instruction-set extension to the open-source RISC-V ISA (RV32IM) dedicated to ultra-low power (ULP) software-defined wireless IoT transceivers. The custom instructions are tailored to the needs of 8/16/32-bit integer complex arithmetic typically required by quadrature modulations. The proposed extension occupies only 2 major opcodes and most instructions are designed to co... » read more

Power/Performance Bits: March 23


Metasurface for optical media Researchers at Purdue University proposed a new way to store information in optical media, such as CDs and DVDs, that could improve both storage capacity and read times. The development focuses on encoding information in the angular position of tiny antennas, allowing them to store more data per unit area. "The storage capacity greatly increases because it is o... » read more

Analysis, Modeling And Characterization Of Multi-Protocol High-Speed Serial Links


Improved analysis, modeling, characterization and correlation methods of multi-protocol high-speed transceivers that utilize T-coil to enhance the transmitter and receiver bandwidth, transmitter FIR filters and receiver CTLE and DFE equalizers is presented. The key circuit blocks are measured and modeled using IBIS-AMI models and the overall system performance including the eye diagrams, BER cu... » read more

Case Study—RF ASIC Validation Of A Satellite Transceiver


ASIC validation in the RF world comes with its own set of hurdles and challenges, with high-quality lab equipment, experience and know-how essential. A recently completed RF sub-system validation at S3 Semiconductors is presented in the form of a case study of the execution. The validation PCB design focussed on impedance matching and shielding RF signals from noise sources. We built up an effi... » read more
