Hillsboro, Ore. - Lattice Semiconductor Corp. has extended the performance range of its fifth-order low-pass filter, ispPAC80, to 750 kHz for Butterworth topologies. The previous top end was 500 kHz. Priced at $8.25 in lots from 100 to 199, this is a single-chip in-system programmable, continuous-time device that offers Chebychev, Legendre, elliptical, Gaussian and linear-phase topologies as well.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
