The Verification Mindset

By Ann Mutschler - 26 Apr, 2021 - Comments: 2

The practice of semiconductor verification has changed substantially over the years, and will continue to do so. The skillset needed for functional verification 20 years ago is hardly recognizable as a verification skillset today, and the same should be expected moving forward as design and verification becomes more abstract, the boundary of what is implemented in hardware versus firmware and s... » read more

Adding Value To Open-Source RISC-V Cores With Verification

By Lee Moore - 22 Apr, 2021 - Comments: 0

By Steve Richmond (Silicon Labs), Mike Thompson (OpenHW Group), and Lee Moore (Imperas Software) Modern SoC verification has matured to the point that some are suggesting the use of the word ‘prototype’ when referring to the first silicon samples is now unnecessary. This is due in part to the commercial EDA industry, which has provided the innovation and tools used throughout the design... » read more

Merging Verification And Test

By Brian Bailey - 22 Apr, 2021 - Comments: 0

While the disciplines of functional verification and test serve different purposes, their histories were once closely intertwined. Recent safety and security monitoring requirements coupled with capabilities being embedded into devices is bringing them closer together again, but can they successfully cooperate to bring about improvements in both? Getting there may be difficult. Three phases ... » read more

RISC-V Targets Data Centers

By Ann Mutschler - 22 Apr, 2021 - Comments: 0

RISC-V vendors are beginning to aim much higher in the compute hierarchy, targeting data centers and supercomputers rather than just simple embedded applications on the edge. In the past, this would have been nearly impossible for a new instruction set architecture. But a growing focus on heterogeneous chip integration, combined with the reduced benefits of scaling and increasing demand for ... » read more

Computing Where Data Resides

By Ann Mutschler - 29 Mar, 2021 - Comments: 3

Computational storage is starting to gain traction as system architects come to grips with the rising performance, energy and latency impacts of moving large amounts of data between processors and hierarchical memory and storage. According to IDC, the global datasphere will grow from 45 zettabytes in 2019 to 175 by 2025. But that data is essentially useless unless it is analyzed or some amou... » read more

What Does RISC-V Stand For?

By Roddy Urquhart - 29 Mar, 2021 - Comments: 1

RISC-V (pronounced “risk-five”) stands for ‘reduced instruction set computer (RISC) five’. The number five refers to the number of generations of RISC architecture that were developed at the University of California, Berkeley since 1981. The RISC concept (like the parallel MIPS development in Stanford University) was motivated by the fact that most processor instructions were not... » read more

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

By Codasip - 24 Mar, 2021 - Comments: 0

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

An Insider’s View Of Verifying Custom RISC-V Processor Cores
