Crate nxpu_backend_core 

Backend trait and plugin architecture for NxPU.

Defines the Backend trait that all NPU code emitters implement, along with supporting types (BackendOptions, BackendOutput, BackendError) and a BackendRegistry for CLI dispatch.

Structs

BackendOptions

Options passed to a backend during compilation.

BackendOutput

The output produced by a backend.

BackendRegistry

Registry of available backends, used for CLI --target dispatch.

BufferAllocation

A buffer allocation for a single tensor.

ConstantTensor

Contents for one tensor, supplied by the caller rather than by the kernel.

Diagnostic

A non-fatal diagnostic message from a backend.

IrDumpBackend

Built-in backend that dumps the IR as text using nxpu_ir::dump_module.

MemoryPlan

The result of memory planning: buffer assignments and peak usage.

OutputFile

A single output file.

PerChannelParam

Per-channel quantization parameters for a weight tensor.

QuantParam

A per-tensor quantization parameter entry.

TensorId

A unique identifier for a tensor in the memory plan.

TilingPlanInfo

A tiling plan passed through to backends.

VectorizationHintInfo

A vectorization hint passed through to backends.

Enums

BackendError

Errors that can occur during backend compilation.

DiagnosticLevel

Severity level for diagnostics.

OutputContent

Content of an output file.

PerformanceTier

Performance tier for an operator on a specific NPU.

Precision

Target precision for NPU compilation.

PrecisionPolicy

Policy for choosing precision during compilation.

Traits

Backend

A backend that compiles NxPU IR to target-specific output.

OperatorSupport

Trait describing which operators an NPU supports and at what performance tier.

Functions

validate_patterns

Validate a set of operator patterns against an OperatorSupport implementation.
