Description

Loaded MPKs, preprocess plans, and the simplified inference entry point.

Enumerations

AutoFlag

enum class simaai::neat::AutoFlag

strong

Tri-state knob: let the planner decide, force on, or force off.

Enumeration values

Auto	Planner decides based on model contract and inputs (= 0)
On	Force this stage on (= 1)
Off	Force this stage off (= 2)

Used pervasively across PreprocessOptions so the application can express "I don't care, do the right thing" (Auto) without losing the ability to override.

Definition at line 32 of file PreprocessPlan.h.

32enum class AutoFlag {

33 Auto = 0,

34 On = 1,

35 Off = 2,

36};

InputKind

enum class simaai::neat::InputKind

strong

What kind of input the user is feeding the preprocess pipeline.

Enumeration values

Auto	Planner infers from caps / sample type (= 0)
Image	Decoded image (planar/packed pixels) (= 1)
Tensor	Already-shaped tensor; preprocess is mostly a pass-through (= 2)

Definition at line 40 of file PreprocessPlan.h.

40enum class InputKind {

41 Auto = 0,

42 Image = 1,

43 Tensor = 2,

44};

NormalizePreset

enum class simaai::neat::NormalizePreset

strong

Common normalize presets — convenient shorthand for famous mean/stddev pairs.

Enumeration values

None	Use the explicit mean/stddev fields (= 0)
ImageNet	Standard ImageNet stats (= 1)
COCO_YOLO	Stats commonly used by YOLO-family detectors trained on COCO (= 2)

Definition at line 67 of file PreprocessPlan.h.

67enum class NormalizePreset {

68 None = 0,

69 ImageNet = 1,

70 COCO_YOLO = 2,

71};

PreprocessColorFormat

enum class simaai::neat::PreprocessColorFormat

strong

Color format hint for the color-convert stage.

Enumeration values

Auto	Planner picks based on caps/contract (= 0)
RGB	Packed 8-bit RGB (= 1)
BGR	Packed 8-bit BGR (= 2)
GRAY8	8-bit single-channel grayscale (= 3)
NV12	Y plane + interleaved UV plane (semi-planar 4:2:0) (= 4)
I420	Y, U, V planes (planar 4:2:0) (= 5)

Definition at line 56 of file PreprocessPlan.h.

56enum class PreprocessColorFormat {

57 Auto = 0,

58 RGB = 1,

59 BGR = 2,

60 GRAY8 = 3,

61 NV12 = 4,

62 I420 = 5,

63};

PreprocessGraphFamily

enum class simaai::neat::PreprocessGraphFamily

strong

Which preprocess graph family the planner selected.

Enumeration values

Disabled	No preprocess graph (model accepts raw tensors) (= 0)
Preproc	Preprocess only; quant/tess happen inside the MLA (= 1)
Quant	Preprocess + quant; tess happens inside the MLA (= 2)
Tess	Preprocess + tess; quant happens inside the MLA (= 3)
QuantTess	Preprocess + quant + tess; nothing happens inside the MLA (= 4)

The four variants correspond to the four corners of the dtype-contract decision tree (BF16/INT8 × inside/outside MLA tess).

Definition at line 76 of file PreprocessPlan.h.

76enum class PreprocessGraphFamily {

77 Disabled = 0,

78 Preproc = 1,

79 Quant = 2,

80 Tess = 3,

81 QuantTess = 4,

82};

ResizeMode

enum class simaai::neat::ResizeMode

strong

How the resize stage maps non-matching input dimensions to the model's input shape.

Enumeration values

Stretch	Anisotropic scale to fit; aspect ratio not preserved (= 0)
Letterbox	Scale to fit while preserving aspect; pad the rest with pad_value (= 1)
Crop	Center-crop to the target shape after isotropic scale (= 2)

Definition at line 48 of file PreprocessPlan.h.

48enum class ResizeMode {

49 Stretch = 0,

50 Letterbox = 1,

51 Crop = 2,

52};

TransformType

enum class simaai::neat::TransformType

strong

Which transformation a Transform represents — used in user-supplied transform lists.

Enumeration values

Resize	Resize / letterbox / crop (= 0)
ColorConvert	Color-format conversion (= 1)
LayoutConvert	Axis permutation (e.g., HWC → CHW) (= 2)
Normalize	Mean/stddev normalization (= 3)
Quantize	INT8 quantization (= 4)
Tessellate	MLA-tile reshuffle (= 5)

Definition at line 86 of file PreprocessPlan.h.

86enum class TransformType {

87 Resize = 0,

88 ColorConvert = 1,

89 LayoutConvert = 2,

90 Normalize = 3,

91 Quantize = 4,

92 Tessellate = 5,

93};
