Data Structures | |
struct | IDMA3_MemRec |
Record containing attributes of the IDMA3 Channel environment memory when (optionally) the IDMA3 Channel is requested with a non-NULL IDMA3_ProtocolObj. More... | |
struct | IDMA3_ChannelRec |
DMA Channel Descriptor to logical DMA channels. More... | |
struct | IDMA3_Fxns |
These fxns are used to query/grant the DMA resources requested by the algorithm at initialization time, and to change these resources at runtime. All these fxns are implemented by the algorithm, and called by the client of the algorithm. More... | |
struct | IDMA3_ProtocolObj |
These functions are used to determine memory requirements for and initialize the IDMA3 protocol's environment that will be allocated by the DMA manager. More... | |
struct | IDMA3_Obj |
IDMA3_Obj holds the private state associated with each logical DMA channel. More... | |
Defines | |
#define | IDMA3_PROTOCOL_NULL ((IDMA3_ProtocolHandle)NULL) |
NULL protocol definition. | |
Typedefs | |
typedef IDMA3_Obj * | IDMA3_Handle |
Handle to "logical" DMA channel. | |
typedef IDMA3_ProtocolObj * | IDMA3_ProtocolHandle |
Handle to IDMA3 protocol object. | |
Enumerations | |
enum | IDMA3_MemType { IDMA3_INTERNAL, IDMA3_EXTERNAL } |
Memory space descriptors for IDMA3_MemRec. More... | |
enum | IDMA3_Priority { IDMA3_PRIORITY_URGENT, IDMA3_PRIORITY_HIGH, IDMA3_PRIORITY_MEDIUM, IDMA3_PRIORITY_LOW } |
IDMA3 Priority Levels. More... |
#define IDMA3_PROTOCOL_NULL ((IDMA3_ProtocolHandle)NULL) |
NULL protocol definition.
The NULL protocol can be used when no protocol is needed, e.g. when the algorithm directly accesses the eDMA PaRAM registers, or when the DMA driver library used does not retain any state. When the NULL protocol is used 'env' buffer is not allocated
typedef struct IDMA3_Obj* IDMA3_Handle |
Handle to "logical" DMA channel.
typedef struct IDMA3_ProtocolObj* IDMA3_ProtocolHandle |
Handle to IDMA3 protocol object.
enum IDMA3_MemType |
Memory space descriptors for IDMA3_MemRec.
enum IDMA3_Priority |
