Supports integration of
accelerated time-to-market for ZSP users. The framework鈥檚 software environment
improves development efficiency by providing a standardized integration
methodology, allowing algorithms from multiple vendors to be used while
maintaining hardware abstraction. The ZOpen framework consists of a rules-
based specification to standardize application development, high-level
application programmer interfaces (APIs), low-level physical interface drivers,
an application module for execution control and a software validation utility.
The ZOpen framework is designed to leverage third-party algorithms and real-
time operating systems (RTOSes) to give maximum flexibility to application
developers. All ZSP platforms, including licensed designs, ASICs and ASSPs,
benefit from the ZOpen framework.

ZOPEN ARCHITECTURE
The ZOpen framework鈥檚 architecture is modular with well-defined interfaces
between functional modules. This architecture provides an open environment
that enables the use of customized modules to meet application requirements.
The ZOpen framework鈥檚 architecture is comprised of three components:
Application Module, Algorithm Modules and Platform Interface Module.
Figure 1 provides a block diagram that shows the architecture of the ZOpen framework.
