TCP2用户手册中的几个问题

Other Parts Discussed in Thread: TMS320C6457

参考文档是sprugk1(TMS320C6457 DSP Turbo-Decoder Coprocessor 2 (TCP2))

1、40 <= Frame Size <=20730时,TCP2使用SA 模式效率更高,SP模式也可以使用,只不过效率低,对吗?

2、 TCP2文档中多次提到“The base address must be double-word aligned”,也就是说该数据的起始地址是64bit对齐吗,即起始地址的最低3位是0,例如0x12345000?

3、文档4.1.1节,Figure6.   Word N出现了3个SP3,认为应该如下:

Word  N+1

Word  N

RSVD

(63:62)

SP9

0

SP8

A1’

SP7

0

SP6

0

SP5

X1

RSVD

(31:30)

SP4

0

SP3

0

SP2

0

SP1

A0

SP0

X0

Word  N+3

Word  N+2

RSVD

(63:62)

SP9

0

SP8

A3’

SP7

0

SP6

0

SP5

X3

RSVD

(31:30)

SP4

0

SP3

0

SP2

0

SP1

A2

SP0

X2

TCP2的6bit量化输入数据格式要拼成成这个格式吗? 同时,sp0、sp1...sp9对应地址是依次递增还是递减?

4、4.1.2节的Table 2. Interleavler Data,有些没看懂,能否解释下表格字段和具体内容含义?

5、6.20节Table 25 的SNR_EXCEED的Value和Desciption是否有歧义,能帮看下吗?

6、能给出函数TCP2_makeTailArgs()的源代码吗?

非常谢谢!
