Software Development
Product Introduction MP211
As cellular phone services become increasingly sophisticated, the amount of software required for design and development is increasing significantly. In addition to the mobile communication software that was required in the early cellular phones, today's third-generation cellular phones have a host of additional requirements such as browser and video support, and the amount of software that is now required has grown to over ten times than that of early mobile phones.
Furthermore, the percentage of man-hours required for software development out of the total number of man-hours spent on cellular phone development is rising, and more efficient software development is required.
To answer this need, NEC Electronics' application processors employ an architecture that makes it possible to reuse one particular software item for various products when designing various versions of a given product.
NEC Electronics' application processors also contribute to more efficient software verification. Since the software operation of each CPU is highly independent from that of the other CPUs, the software for each CPU can be developed independently. As a result, when new applications are added, existing applications that have already been verified need not be verified again and verification can be concentrated on the new applications, which greatly simplifies verification.
This also has the advantage of simplifying the estimation of chip performance since applications are clearly assigned to specific CPUs.
