Description

The AT75C DSP subsystem is an autonomous DSP-based computation block that co-exists on-chip with other processors and functions. It is built around a 16-bit, fixed-point, industry-standard OakDSPCore. Additionally, the DSP subsystem embeds allelements necessary to run complex DSP algorithms independently without any exter-nal resources.

The AT75C self-contained subsystem contains the OakDSPCore itself, program memory,data memory, an on-chip emulation module and a flexible codec interface. Theseresources allow the subsystem to run complex DSP routines, such as V.34 modememulation or state-of-the-art voice compression.

The AT75C codec interface permits connection of any external industry-standard codecdevice, allowing the DSP subsystem to handle directly external analog signals such astelephone line or handset signals.Communication between the DSP subsystem and the on-chip ARM7TDMI™ core isachieved through a semaphore-operated dual-port mailbox.
