TC1767
Introduction
Data Sheet
18
V1.3, 2009-09
Each SRN can be mapped to the CPU or PCP interrupt system
Flexible interrupt-prioritizing scheme with 255 interrupt priority levels per SRN to
choose from
2.3.2
Direct Memory Access Controller
The TC1767 includes a fast and flexible DMA controller with independant DMA channels
( DMA Move engine).
Features
independent DMA channels
– Up to 16 selectable request inputs per DMA channel
– 2-level programmable priority of DMA channels within the DMA Sub-Block
– Software and hardware DMA request
– Hardware requests by selected on-chip peripherals and external inputs
3-level programmable priority of the DMA Sub-Block at the on chip bus interfaces
Buffer capability for move actions on the buses (at least 1 move per bus is buffered)
Individually programmable operation modes for each DMA channel
– Single Mode: stops and disables DMA channel after a predefined number of DMA
transfers
– Continuous Mode: DMA channel remains enabled after a predefined number of
DMA transfers; DMA transaction can be repeated
– Programmable address modification
– Two shadow register modes (with / w/o automatic re-set and direct write access).
Full 32-bit addressing capability of each DMA channel
– 4 Gbyte address range
– Data block move supports > 32 Kbyte moves per DMA transaction
– Circular buffer addressing mode with flexible circular buffer sizes
Programmable data width of DMA transfer/transaction: 8-bit, 16-bit, or 32-bit
Register set for each DMA channel
– Source and destination address register
– Channel control and status register
– Transfer count register
Flexible interrupt generation (the service request node logic for the MLI channel is
also implemented in the DMA module)
DMA module is working on SPB frequency, LMB interface on LMB frequency.
Dependant on the target/destination address, Read/write requests from the Move
Engine are directed to the SPB, LMB, MLI or to the the Cerberus.
