Table 1142.  Registers
Name Description
Input Section

The IP reads the debug registers relating to the input section of the Warp IP using the intel_vvp_warp_get_input_debug_register () API call.

INPUT_FRAME_COUNT

A count of the number of frames that have started at the input of the Warp IP. The last frame counted may be incomplete.

This counter can indicate the video activity at the input of the Warp IP. Sampling this count periodically indicates frame rate. A static count indicates that the upstream pipeline to the Warp IP is not producing video data.

INPUT_FRAME_PERIOD

The number of axi4s_vid_in_0_clock cycles seen between the last two start of frames seen at the input.

Use this counter to indicate the frame rate by comparing its value with the input clock frequency. If the value from this register varies greatly, it indicates an unstable processing pipeline upstream of the Warp IP.

INPUT_MEM_DIRECT_WRITES

The number of blocks of direct, non-mipmap data the IP writes to memory during the processing of the last frame of input data. A block is defined as a 16x8 region of pixel data.

INPUT_MEM_MIPMAP_WRITES

The number of blocks of mipmap data the IP writes to memory during the processing of the last frame of input data. A block is defined as a 16x8 region of pixel data. This value is only available when Use mipmap is on.

Output Section

The debug registers relating to the output section of the Warp IP are read using the intel_vvp_warp_get_output_debug_register () API call.

OUTPUT_FRAME_COUNT

A count of the number of frames that have started at the output. The last frame counted may be incomplete.

This counter can indicate the video activity at the output of the Warp IP. Sampling this count periodically gives an indication of frame rate and a static count indicates that the downstream pipeline from the Warp IP is blocked and not accepting video data.

OUTPUT_FRAME_PERIOD

The number of axi4s_vid_out_0_clock cycles seen between the last two start of frames seen at the output.

This counter can indicate the frame rate by comparing its value with the output clock frequency. If the value from this register varies wildly, it indicates an unstable processing pipeline downstream of the Warp IP.

Engine Section

The debug registers relating to the engine section of the Warp IP are read using the intel_vvp_warp_get_engine_debug_register () API call.

ENGINE_FRAME_COUNT

A count of the number of frames that have started to be processed by the engine being referenced. The processing of the last frame counted may be in progress.

This counter is useful for indicating the video activity within the Warp IP. It gives an indication that the Warp IP is set up and that the engine is configured to process correctly.

ENGINE_FRAME_PERIOD

The number of core_clock cycles seen between the last two start of frames seen at the engine.

This counter is useful for confirming that the core_clock is set correctly given the expected frame rate. It is also useful for comparing against the ENGINE_BUSY _CYCLES value as an indication of how busy the engine is.

ENGINE_BUSY CYCLES

The number of core_clock cycles for which the engine actively processes video data during the last frame. The counter starts when the processing of a frame begins and continues until either the IP completes the frame or encounters the start of the next frame. For the latter the engine fails to complete the processing of the frame in time, refer to the ENGINE_FAILED_TO_COMPLETE_FRAME status indicator.

When compared to the ENGINE_FRAME_PERIOD, the value of ENGINE_BUSY_CYCLES gives an indication of how busy an engine is during the processing of a frame.

ENGINE_FRAME_DELAY

The number of core_clock cycles between the start of the last input frame and the start of the engine’s processing phase.

Use this counter for low latency behavior to determine if you have enough delay when programming the low latency settings. It also indicates the input and output frame synchronization that is a requirement for correct low latency behavior. This delay must be stable for low latency IPs to work correctly. If the IP does not see a stable value, the delay is changing over time, which indicates the input to output frame synchronization may not be operating correctly.

ENGINE_FAILED_TO_COMPLETE_FRAME

A sticky flag that indicates that the engine has failed to complete the processing of a frame in the required frame period. The flag is cleared each time it is interrogated.

The IP sets this to indicate that the engine has not had sufficient time to process the video frame as required and image corruption occurs. The most likely reason is insufficient memory bandwidth available to the engine. Insufficient memory bandwidth gives processing stalls either while waiting for read data to return or stalls while blocked waiting for write data is sent out.

ENGINE_RUN_STATUS

This value is only relevant when Use single memory bounce is on.

The lower 16 bits of the value indicate the lowest buffering level the IP reaches during the processing of the previous frame. The buffering level is the difference between the write position and the read position of the current cache accesses. If this value is 0, it indicates that the engine stalls during the processing of the frame. This stall can give unstable output video when Use single memory bounce is on.

The upper 16 bits of the value is the output line at which the IP reaches the lowest buffering level. They indicate at which point in the transform this output line occurs.

ENGINE_CACHE_LOADS The number of cache loads the IP produces while the IP processes the previous frame. Each cache load reads a 16x8 pixel block (128 pixels in total). The total number of cache reads indicates the memory bandwidth load that the current warp transform is placing on the memory.

General Section

The debug registers relating to the general section of the Warp IP are read using the intel_vvp_warp_get debug_register () API call.

MEM_WR_QUEUES0

Indicates the number of internal requests that queue at any one time for each of the write accesses through the Warp IP’s memory controller. The IP stores each queue depth value as a byte in the 32-bit data word returned by the read to this register. The IP has a number of queues depending on the configuration (Separate Queue Values (Write Accesses)).

MEM_RD_QUEUES0 and MEM_RD_QUEUES1

Indicates the number of internal requests that queue at any one time for each of the read accesses through the Warp IP’s memory controller. The IP has two 32 bit registers for access to the read queue depths. Each individual queue depth value is stored as a nibble in the 32 bit data word returned by a read to one of these registers. The IP has a number of queues depending on the configuration (Separate Queue Values (Read Accesses))

MEM_RD_ACCESSES

The number of active memory read accesses issued by the Warp IP in the last second that were not blocked by the av_mm_memory_host_waitrequest signal. Each access represents a burst of eight cycles of data on the memory bus so the reported value should be multiplied by eight to get the number of actual read data transfer cycles.

MEM_WR_ACCESSES

The number of active memory write access cycles issued by the Warp IP in the last second that were not blocked by the av_mm_memory_host_waitrequest signal. This value represents the actual number of data transfer cycles that were active on the memory bus.

MEM_STALLED_ACCESSES

The number of cycles on the memory bus for which the IP blocks a read or write access cycle because of asserting of the av_mm_memory_host_waitrequest signal.
Table 1143.  Separate Queue Values (Write Accesses)

The table shows the separate queue values for each configuration. The maximum depth value for each write queue is 48. If periodically sampling of the queue depth values finds them to be close to or at this maximum value, it indicates a limitation on write bandwidth from the IP to the external memory because the queues are filling up and blocking throughput.

Engine 0 Write N/A MEM_WR_QUEUES0[15:8] MEM_WR_QUEUES0[15:8]
Engine 1 Write N/A N/A MEM_WR_QUEUES0[23:16]
Table 1144.  Separate Queue Values (Read Accesses)The table shows the separate queue values for each configuration.

The maximum value for each read queue depth is 12. If periodically sampling of queue depth values finds them close to or at this maximum value, it indicates a limitation on read bandwidth from the IP to the external memory because the queues are filling up and blocking throughput.
