An Open ISA, a Closed Mindset — Predictive Execution Charts a New Path
The RISC-V revolution was never just about open instruction sets. It was a rare opportunity to break free from the legacy assumptions embedded in every generation of CPU design. For decades, architectural decisions have been constrained by proprietary patents,… Read More
The transition to the digital age from a mostly analog world really began with the invention of the A-to-D and D-to-A converters. However scalar processors can easily be overwhelmed by the copious data produced by something as simple as an audio stream. To solve this problem and to really jumpstart the digital age, the development… Read More
What we think of as a “baseband processor” for cellular networks is often comprised of multiple cores. Anecdotes suggest to handle the different signal processing requirements for 2G, 3G, and 4G networks, some SoC designs use three different DSPs plus a control processor such as an ARM core. That’s nuts. What is the point of having… Read More
For some time, we’ve been talking about ideas for IoT-specific chips, evolved from garden-variety MCUs or mobile SoCs. I sat in on a fascinating talk from an MCU vendor at ARM TechCon 2015 regarding multi-protocol radio silicon, and a question kept coming from the audience: what about software-defined modems? The vague response… Read More
