Parameters
| Name | Type | Range | Default | Description |
|---|---|---|---|---|
| work_mode | unsigned | 0 for Pipeline, 1 for Req-ack | 0 | This module's working mode. |
| window_width | unsigned | 2 - 15 | 3 | The width(and height) of window. |
Ports
| Name | Port | Type | Range | Default | Description |
|---|---|---|---|---|---|
| clk | input | unsigned | None | None | Clock. |
| rst_n | input | unsigned | None | None | Reset, active low. |
| template | input | unsigned | window_width * window_width - 1 : 0 | None | Reset, active low. |
| in_enable | input | unsigned | None | None | Input data enable, in pipeline mode, it works as another rst_n, in req-ack mode, only it is high will in_data can be really changes. |
| in_data | input | unsigned | window_width * window_width - 1 : 0 | None | Input data, it must be synchronous with in_enable. |
| out_ready | output | unsigned | None | None | Output data ready, in both two mode, it will be high while the out_data can be read. |
| out_data | output | unsigned | None | None | Output data, it will be synchronous with out_ready. |

HDL functional simulation for pipeline mode is on the left, for req-ack mode is on the middle, and which on the right is the soft simulation

The max Data Path Delay is 2.199ns, so:
FMax = 454.75MHz
