Register

Offset

Attribute

Description

Intermediate_ddr_base_address

0x000

RW

Base address for the DDR intermediate data. This is a shared address across all graphs. Only required to be set once upon startup. Must be aligned to a multiple of the DDR word size.

Inference_completion_count

0x004

RO

Number of inference request completions by the FPGA AI Suite IP.

IP_reset 0x008 RW Write any non-zero value to this address to trigger a reset of the FPGA AI Suite IP.

The value is automatically cleared upon reset.

Reading from this register always returns 0.

Activate_streaming 0x00C RW When streaming is enabled in the architecture, writing "1" to this register makes the FPGA AI Suite IP begin queuing descriptors and start listening for streaming inputs.

Writing "0" stops queuing descriptors and turns off the input streaming interface.
