Figure 4. ADSP-TS201S Shared Memory Multiprocessing System
external memory. These transfers only use handshake mode protocol. DMA priority rotates between the four receive channels.
•AutoDMA transfers. Two dedicated unidirectional DMA channels transfer data received from an external bus master to internal memory or to link port I/O. These transfers only use slave mode protocol, and an external bus master must initiate the transfer.
The DMA controller provides these additional features:
•Flyby transfers. Flyby operations only occur through the external port (DMA Channel 0) and do not involve the DSP’s core. The DMA controller acts as a conduit to trans- fer data from an I/O device to external SDRAM memory.
During a transaction, the DSP relinquishes the external data bus; outputs addresses and memory selects
•DMA chaining. DMA chaining operations enable applica- tions to automatically link one DMA transfer sequence to another for continuous transmission. The sequences can occur over different DMA channels and have different transmission attributes.
