... Typical Applications: MP3 Player, Musical Instruments, Consumer Electronic, Effect Devices 1. Description The ATSAM3303B is a member of the new ATSAM3000 family that uses the DSP array technology. The ATSAM3303B includes three 24-bit DSPs, a 24-bit Audio Router and a general-purpose 16-bit on-chip CISC microcontroller. Its high perfor- mance and flexibility allow implementation of professional-quality audio applications, such as MP3 decoding, Wavetable synthesis, effect processing and mixing ...

... Functional Description 3.1 DSP Array The ATSAM3303B includes three on-chip DSPs. Each DSP (P24) is built around RAM and ROM. The RAM contains both data and P24 instructions; the ROM contains typical coefficients such as FFT cosines and win- dowing. A P24 sends and receives audio samples through the Sync Bus. It can request external data such as compressed audio through the Async Bus ...

... MMU (Memory Management Unit) The MMU handles transfer requests between the external or embedded RAM/ROM, the P16 and the P24s through the Async Bus. The ATSAM3303B includes an on-chip 16K x 24 RAM. 3.6 Router: Final ACC, MIX, Audio Out, Audio In This block includes a RAM, accessed through the Async Bus, which defines the routing from the Sync Bus to/from the Audio I/O or back to the Sync Bus (mix send) ...

... Stereo 31-band equalizer @48 kHz The ATSAM3303B runs firmware directly from an external ROM/Flash memory. It may also run firmware from local RAM, thus freeing many I/O pins, which can then be used for application- dependent functions. The ATSAM3303B is the ideal choice when wavetable synthesis or many I/O pins are required ...
