1 / 171 page  1 Features • Fully Autonomous DSP System • 16-bit Fixed-point OakDSPCore® • 24K x 16 of Uploadable Program RAM • 16K x 16 of Data RAM • 2K x 16 of X-RAM • 2K x 16 of Y-RAM • X-RAM and Y-RAM Accessible within the Same Cycle • JTAG Interface Available on AT75C220 and AT75C320 • On-chip Emulation Module • Flexible Codec Interface • Communication with External Processor through Dual-port Mailbox 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.
