Ð On-Chip Emulation (OnCE

Ô

) module

Ð Joint test action group (JTAG) test access port (TAP)

Ð Address trace mode reflects internal Program RAM accesses at the external port

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.
