We are now entering the tail end of an era, and many of us do not even know it. For as long as there have been microprocessors, there have been engineers and engineering teams whose job it was to create interconnects. Although this will undoubtedly continue in some companies, the increasing complexity of systems-on-a-chip (SoCs) […]
There is a growing productivity gap in the design of embedded systems. One recent survey estimated that the number of lines of embedded code written per year is growing at a rate of 46% a year, although the number of developers available to write it is growing at only 7.5%. The problem is further compounded […]
How do we bridge the gap between the highly abstract view provided by traditional system-level design and the detailed implementation in RTL? The article answers this question by describing the components within an ESL methodology and illustrating its use via customer case studies. The methodology uses the ARM RealView SoC Designer tool and Tenison Design […]
In late 2001, Nick Baker and other members of the Ultimate TV team at Microsoft learned that the company was ending development work on the product. For a still youthful engineer whose curriculum vitae already took in some ill-fated early-days video card work at Apple and the short-lived 3DO games console, Baker could have been […]
Consumer electronics is a difficult business.Market windows open and close quickly. Cost is critical. Requirements change unpredictably. Risk is high. Functionality and performance increase with every product generation, while both manufacturing-limitations and feature-driven demand require low power implementations. Of all these, power constraints have the largest impact on current product architectures. As CMOS reaches its […]
Timing closure is one of the major problems faced by SoC designers. The inclusion of several, often diverse, IP cores that need to communicate with each other on a chip makes it difficult for a designer to meet the complex timing requirements between these cores. Furthermore, as process nodes shrink, process variability becomes a more […]
SystemC [1] is rapidly becoming the language of choice for ESL-centric design methodologies. It is set to become the framework for higher-level flows above today’s RTL, and has three key components: modeling, synthesis and verification. High-level modeling particularly demonstrates the language’s versatility and advantages. Strong progress is also being made in higher-level synthesis. However, our […]
Designers thinking about low power and energy have a variety of strategies at their disposal. The most common are: Process/libraries (e.g. low-power processes/libraries; high and low threshold voltage cells; and voltage scaling); Power and voltage domains; Clock gating; Low-power optimized clock synthesis; Low-power synthesis (e.g. automatic insertion of operand isolation circuitry); Implementation optimizations (e.g. operand […]
As the third wave of the digital revolution finally gains momentum, the chip industry is breaking loose from its homogeneous telecom/PC-centric confines – where everyone’s product and box essentially looked and worked the same – into the arms of the fragmented consumer-centric heterogeneous multimedia, with significantly more brand names and lots of different price points. […]
For years, ASIC and FPGA designers have shared the goal of having totally reusable intellectual property (IP) blocks. This goal has been partially fulfilled, with the introduction of high-level hardware description languages such as VHDL and Verilog, and powerful Register Transfer Level (RTL) synthesis tools in the late 1980s and early 1990s. However, with a […]
