说明 |
---|---|---|
tl_cfg_add[3:0] H-Tile tl_cfg_add[4:0] L-Tile |
Output |
TLP寄存器的地址。此信号是一个索引,表明哪个Configuration Space寄存器被驱动到tl_cfg_ctl。请参考H-Tile Multiplexed Configuration Register Information Available on tl_cfg_ctl或者 E-Tile Multiplexed Configuration Register Information Available on tl_cfg_ctl来获取可用信息。 Address of the TLP register. This signal is an index indicating which Configuration Space register information is being driven onto tl_cfg_ctl. Refer to L-Tile Multiplexed Configuration Register Information Available on tl_cfg_ctl for the available information. |
tl_cfg_ctl[31:0] | Output |
Tl_cfg_ctl信号是多路复用的,包含Configuration Space寄存器的一组内容。 |
tl_cfg_func[1:0] | Output | 指定功能,此功能的Configuration Space寄存器值被驱动到tl_cfg_ctl[31:0]。下面编码定义为:
|
app_err_hdr[31:0] | Input | 错误TLP的header信息。四个4-byte传输发送此信息到IP core。 |
app_err_info[10:0] | Input | Application可以选择提供以下信息:
|
app_err_valid | Input | 置位时,表明app_err_info[10:0]上的数据是有效的。对于多功能类别,app_err_func_num指定其功能。 |
