New Processor Fuzzing Mechanism


Researchers from Boston University and University of Washington published a technical paper titled "ProcessorFuzz: Guiding Processor Fuzzing using Control and Status Registers." Abstract "As the complexity of modern processors has increased over the years, developing effective verification strategies to identify bugs prior to manufacturing has become critical. Undiscovered micro-architectur... » read more

High-Level Synthesis For RISC-V


High-quality RISC-V implementations are becoming more numerous, but it is the extensibility of the architecture that is driving a lot of design activity. The challenge is designing and implementing custom processors without having to re-implement them every time at the register transfer level (RTL). There are two types of high-level synthesis (HLS) that need to be considered. The first is ge... » read more

What’s So Important About Processor Extensibility?


While the ability to extend a processor is nothing new, market dynamics are forcing a growing percentage of the industry to consider it a necessary part of their product innovation. From small IoT functions to massive data centers and artificial intelligence, the need to create an optimized processing platform is often the only way to get more performance or lower power out of the silicon area ... » read more

Chiplets, Faster Interconnects, More Efficiency


Big chipmakers are turning to architectural improvements such as chiplets, faster throughput both on-chip and off-chip, and concentrating more work per operation or cycle, in order to ramp up processing speeds and efficiency. Taken as a whole, this represents a significant shift in direction for the major chip companies. All of them are wrestling with massive increases in processing demands ... » read more

ARM Cortex-M For Beginners


The ARM Cortex-M family now has six processors. In this paper, we compare the features of various Cortex-M processors and highlight considerations for selecting the correct processor for your application. The paper includes detailed comparisons of the Cortex-M instruction sets and advanced interrupt capabilities, along with system-level features, debug and trace features, and performance compa... » read more

How To Choose A Processor


Choosing a processor might seem straightforward at first glance, but like many engineering challenges it's harder than it looks. When is a CPU better than a GPU, MCU, DSP or other type of processor? And for what design—or part of a design? For decades, the CPU has been the default choice. “It is deliberately designed to be pretty efficient at all tasks, is straightforward to program, ... » read more

Revolutionizing The Connected World


One of the 21st century’s biggest global developments is the evolution of connectivity. If you had asked someone 20 years ago what they understand the word ‘connected’ to mean, it is unlikely they would associate it so firmly with technology. Mobile technology has transformed the way in which we interact with one another. We are surrounded by a rapidly growing network of connected devi... » read more

x86 Processor Road Map No Longer Just About Speed


By Ed Sperling The decades-old approach of powerful processors with ever-faster clock speeds is changing. Performance matters in some settings, but the real concern is adding more functionality within power budgets. The most pressing tradeoff is now performance vs. power, which has forced processor architects at AMD, Intel and IBM to take into account everything from application software to... » read more

Hot Chips 2009: It’s All About Multicore And Low-Power


By Pallab Chatterjee The game has changed for processors. The goal now is data throughput, not higher gigahertz and more watts. That shift dominated the presentations at the Hot Chips conference this week. In previous years, the theme was higher single-core performance, more power and smaller geometries processes. This year it was all about multi-core and multi-power options as the realities ... » read more
