APPLICATIONS

The DSP56307 is intended for applications requiring a large amount of on-chip memory, such as

wireless infrastructure applications. The EFCOP may be used to accelerate general filtering

applications, such as echo-cancellation applications, correlation, and general purpose

convolution-based algorithms.
