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 all
elements necessary to run complex DSP algorithms independently without any exter-
nal resources.
The self-contained subsystem contains the OakDSPCore itself, program memory,
data memory, an on-chip emulation module and a flexible codec interface. These
resources allow the subsystem to run complex DSP routines, such as V.34 modem
emulation or state-of-the-art voice compression.
The codec interface permits connection of any external industry-standard codec
device, allowing the DSP subsystem to handle directly external analog signals such as
telephone line or handset signals.
Communication between the DSP subsystem and the on-chip ARM7TDMI core is
achieved through a semaphore-operated dual-port mailbox.
