31 *
32 * Required #defines:
33 * ------------------
34 * TASKSETUP_NAME:
35 * TaskSetup function name, set to TaskSetup_<TASK_NAME>
36 * TASK_API:
37 * task API defined in dma_image.h
38 * MAX_BD:
39 * <=0 : non-BD task
40 * else: number of BD in BD table
41 * BD_FLAG:
42 * 0 : no flag implemented for BD
43 * else: flags can be passed on a per BD basis
44 * MISALIGNED:
45 * 0 : task API supports Bytes%IncrBytes==0
46 * else: task API supports any parameter settings
47 * AUTO_START:
48 * <-1 : do not start a task after task completion
49 * -1 : auto start the task after task completion
50 * <MAX_TASKS: auto start task with the TaskID = AUTO_START
51 * else : do not start a task after task completion
52 * INITIATOR_DATA:
53 * <0 : runtime configurable
54 * else: assume INITATOR_DATA equal hard-coded task initiator
55 * TYPE_SRC: (needs to be consistent with Task API)
56 * FLEX_T : Task API TYPE_SRC = flex, SzSrc defines size
57 * UINT8_T : Task API TYPE_SRC = char
58 * UINT16_T: Task API TASK_SRC = short
59 * UINT32_T: Task API TASK_SRC = int
60 * INCR_TYPE_SRC:
61 * 0 : FIFO address, do not implement data pointer
62 * 1 : automatic, set INCR_SRC based on SzSrc parameter
63 * 2 : runtime, set INCR_SRC to IncrSrc parameter
64 * else: used hard-coded INCR_SRC
65 * INCR_SRC:
66 * INCR_TYPE_SRC=0: force INCR_SRC=0
67 * else : use for src pointer increment
68 * TYPE_DST: (needs to be consistent with Task API)

77 * else: used hard-coded INCR_DST
78 * INCR_DST:
79 * INCR_TYPE_DST=0: force INCR_DST=0
80 * else : use for dst pointer increment
81 * PRECISE_INCREMENT:
82 * 0 : increment when possible
83 * else: increment at end of iteration
84 * NO_ERROR_RESET:
85 * 0 : reset error flags on task enable
86 * else: leave error flags unmodified on task enable
87 * PACK_DATA:
88 * 0 : do not pack data
89 * else: pack data based on data type
90 * INTEGER_MODE:
91 * 0 : type conversions handle as fixed point numbers
92 * else: type conversions handle as integers
93 * WRITE_LINE_BUFFER:
94 * 0 : do not use write line buffers
95 * else: enable write line buffers
96 * READ_LINE_BUFFER:
97 * 0 : do not use read line buffers
98 * else: enable read line buffers
99 * SPEC_READS:
100 * 0 : do not speculatively read
101 * else: speculatively read data ahead of DMA engine
102 *
103 * Optional #defines:
104 * ------------------
105 * MAX_TASKS:
106 * 1 : #define MAX_TASKS>0
107 * else: 16
108 * ITERATIONS:
109 * 1 : #define ITERATIONS>0
110 * else: 1
111 * INCR_BYTES:
112 * This macro is defined based on following priority:
113 * 1 : INCR_SRC != 0
114 * 2 : DST_TYPE != 0
115 * 3 : #defined INCR_BYTES<0
116 * else: -4 (SZ_UINT32)
117 * DEBUG_BESTCOMM_API:
118 * >0 : print basic debug messages
119 * >=10: also print C-API interface variables
120 * >=20: also print task API interface variables
121 * else: do nothing
