2.2.7. interface
Parameter | Applicable Interface | Description |
---|---|---|
name | All | For global_mem: instance name of the Platform Designer component. For channels: instance name of the Platform Designer component that has the channel interface. For interfaces: name of the entity in which the kernel interface resides (for example, board). |
port | For global_mem: name of the Avalon®-MM interface in the Platform Designer component that corresponds to the interface attribute. For channels: name of the streaming interface in the Platform Designer component. For interfaces: name of the interface to the OpenCL™ Kernel Interface Platform Designer component. For example, kernel_cra is the Avalon®-MM interface, and kernel_irq is an interrupt. |
|
type | For global_mem: set to agent. For channels:
For interfaces: set to either host, irq, or streamsource. |
|
width | For global_mem: width of the memory interface in bits. For channels: number of bits in the channel interface. For interfaces: width of the kernel interface in bits. |
|
waitrequest_allowance | For global_mem: [Optional] Amount of Avalon-MM waitrequest allowance supported on the agent interface (that is, kernel-facing interface) of the clock-crossing bridge that spans between the memory and the kernel clock domains. For kernel_cra: [Optional] Amount of Avalon-MM waitrequest allowance that the kernel_cra agent interface must support. This parameter defaults to 0 if you do not specify it in the board_spec.xml file. A value of 0 indicates that this waitrequest allowance feature is disabled. |
|
maxburst | global_mem | Maximum burst size for the agent interface.
Attention: The value of width ÷ 8 x maxburst must be less than the value of interleaved_bytes.
|
address | Starting address of the memory interface that corresponds to the host interface-side address. For example, address 0 should correspond to the bank1 memory host from the OpenCL Memory Bank Divider. In addition, any non-zero starting address must abut the end address of the previous memory. |
|
size | Size of the memory interface in bytes. The sizes of all memory interfaces should be equal. | |
latency_type | If the memory interface has variable latency, set this parameter to average to signify that the specified latency is considered the average case. If the complete kernel-to-memory path has a guaranteed fixed latency, set this parameter to fixed. | |
chan_id | channels | A string used to identify the channel interface. The string may have up to 128 characters. |
clock | interfaces | For the streamsource kernel interface type, the parameter specifies the name of the clock that the snoop stream uses. Usually, this clock is the kernel clock. |
