Modern semiconductor Modern semiconductor fabrication technology has made the incremental cost of producing embedded microprocessors essentially free. Consequently, uniprocessors are now giving way to multiprocessor system configurations. For high performance systems the design challenge has become leveraging and scaling free processors to maximize application performance and efficiency. Deeply coupled processor architectures combined with System-on-Chip implementation technologies are enabling new, economically attractive parallel processor system implementations as well as opportunities for improved programming flexibility and system-level co-development automation. CPU Technology presents a fourth generation, deeply coupled multiprocessor architecture, a cost-efficient System-on-Chip implementation methodology and software co-development tools to enable cost-effective implementations of a broad range of high performance electronic systems. CPU TECH introduces a significant breakthrough in general-purpose parallel system architecture called Deeply Coupled Computing. This breakthrough will have a profound impact on the future of high performance computing, giving birth to an era where any mainstream software application can be productively accelerated. In the near future, hundreds of deeply coupled 64-bit processors will fit compatibly onto a PC motherboard making parallel computing practical for everyone. Deep Coupling describes a trend toward ultra-low inter-processor communication and synchronization latency in high performance computing architectures where processors interact at intervals which range from less than one millionth of a second in large-scale systems to instantaneous on-chip. Deeply Coupled Computers will allow application developers to exploit parallelism from seemingly sequential code. What is System-on-a-Chip (SoC)? SoC technology is the next step in the evolution of computer science. Unlike a big chip stuffed mainly with random (glue) logic, SoC is designed as a programmable platform that integrates most of the functions of the end product in a single chip. It incorporates at least one processing element (microprocessor, DSP, etc.) that runs the system´s embedded software. SoC includes peripherals, random logic and interfaces to the outside world and employs a bus-based architecture. It may contain both memory and analog functions. The ability to produce SoCs is a result of new manufacturing techniques that are capable of producing ever-smaller transistors and putting more of them on a single chip - Moore´s Law in action - and the development of new tools that make it possible to automate the design and verification of such complex devices. is that it has now become possible to create complex electronic systems that are very small and portable, use very little power and are very reliable. Miniature cell phones and digital cameras are good examples. Thus far, SoCs have been used almost exclusively in high volume consumer applications, since they are the ones that have the armies of engineers and can afford the burden of time, cost and risk involved in the traditional development of an SoC based system. The broad-based application of SoC demands a new and very complex design methodology. SoC development requires a highly skilled design team with extensive system-level knowledge, very high quality tools, the availability of embeddable memory elements, logic and processor cores and a stable manufacturing process. The ability to perform system-level verification in a virtual environment before committing to manufacturing is also essential, and the tools to accomplish this are not yet available on the market.
CPU TECH´s tools, engineers and intellectual property allow development of new SoC based open systems which are compatible in every way with legacy application software ("plug and play"). This capability is unique in the market place and enables, for the first time, economical hardware-based solutions to massive, embedded systems obsolescence problems. CPU Tech´s methodology has made SoC based systems affordable even for low volume applications. All existing software, including tools, can be used unchanged on the new system. And the entire cost can often be recovered from a few years´ savings on maintenance. An additional added value is that it also becomes steadily cheaper to re-modernize systems in the future to take advantage of technological advances. Modernization of legacy systems using SoC can solve a number of critical problems. The number of components in a 15 year old computer, for example, can be reduced 100:1 or more. Reliability can be increased and maintenance costs dramatically reduced. Performance is readily improved tenfold or better.
