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 […]
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 […]
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 […]
The advent of extreme fine line processes at 130nm or less presents many challenges. On the back end, optimizing a design to manage physical effects such as power, heat, and timing is more daunting than ever. At the front end, implementing a system-on-chip’s (SoC) behavior and features is becoming equally difficult. The early exploration of […]
No one disputes the promise inherent in the concept of design reuse. But the true value of what has been delivered so far is often debated. This paper proposes a reuse methodology that is both practical and real and which uses behavioral synthesis as its driving technology. It discusses the most basic elements of behavioral […]
Alcatel Space supplies complete satellites for use in geostationary and low-earth orbit as well as custom designs for specific missions. These are based on various in-house platforms which support different payloads according to their final use. Fields serviced include telecommunications, observation, meteorology, navigation and science. The company has 5,600 employees, of which around 2,000 work […]
