Application convergence

Driven by the consumer's hunger for features, various technologies are coming together in single appliances. Not far down the road will be cell phones with video capability.

Convergence can also mean different technologies combining for one application. Convergence is also vital in cars, where silicon vendors are developing processor-based chips that deal with several functions concurrently.

But application convergence poses a formidable challenge to silicon IP providers. Designing systems that deal with multiple technologies is not as simple as combining single application-specific subsystems within the same package. Such designs can result in systems with unnecessary redundancy. They also put an unnecessary strain on system resources, such as the OS, and require a larger memory footprint. Vendors must be able to integrate technologies efficiently.

One way to accomplish integration is via configurable-processing engines. One example is a soft microprocessor core that can process both video and audio information by using instruction-set extensions. Such a core results in a system that has a lower clock frequency and, hence, lower power, than one that uses two processor cores to handle audio and video separately. Configurable and extendable processor cores also allow you to choose the best combination of speed, area and power for a specific application.

The challenge of successfully designing silicon IP for application convergence goes beyond the technology you need to integrate application-specific subsystems. Vendors must also deal with the realities of shrinking design cycles and leaner design teams. To exponentially increase design complexity, you need a design team that can work with different technologies concurrently.

Those companies that wish to excel as silicon IP providers must adopt a business model that addresses the technological convergence of products and companies. The successful silicon IP providers will morph into silicon system providers and will offer a complete package: silicon; software; and, most important, end-use knowledge. The silicon IP provider that has proven knowledge of vertical markets is an invaluable member of the customer's team and, in fact, extends the customer's design expertise without additional head count.
