Description

SimaAI-specific nodes (decode/encode/preproc/postproc).

Enumerations

SimaBEVPoolPlanFormat

enum class simaai::neat::SimaBEVPoolPlanFormat

strong

Layout of a SimaBEVPoolPlan plan, which SimaBEVPool must be told.

Enumeration values

V1	Points grouped by BEV cell (= 1)
V2	Work tiles with planned cache loads, for EV74 SimaBEVPool (= 2)

Definition at line 61 of file SimaKernelTypes.h.

SimaBEVPoolStorage

enum class simaai::neat::SimaBEVPoolStorage

strong

Byte order of a SimaBEVPool depth, context or BEV tensor.

Enumeration values

ChannelsLast	Channels innermost
Contiguous	Logical order

Definition at line 30 of file SimaBEVPool.h.

SimaKernelTarget

enum class simaai::neat::SimaKernelTarget

strong

Hardware that executes a kernels-library Node.

Enumeration values

A65	Application CPU (Arm Cortex-A65)
EV74	EV74 vector DSP

The selected target is final: preparation fails if the operation has no implementation for it. There is no automatic fallback to another target.

Definition at line 22 of file SimaKernelTypes.h.

SimaQuantRounding

enum class simaai::neat::SimaQuantRounding

strong

Integer rounding applied after the binary32 product of a fused quantization.

Enumeration values

NearestEven	Round half to even (default)
TowardZero	Truncate
TowardPositive	Ceiling
TowardNegative	Floor

Definition at line 32 of file SimaKernelTypes.h.
