Class CPUDevice

constructor

• new CPUDevice(): CPUDevice

  Returns CPUDevice

Readonlyid

Readonlytype

createData

• createData(byteLength: number): DeviceData

  Allocate data on the CPU

  Parameters

  • byteLength: number

  Returns DeviceData

disposeData

• disposeData(data: DeviceData): void

  Free CPU memory

  For CPU backend, this is mostly a no-op as JavaScript handles GC, but we can clear the buffer reference to help GC.

  Parameters

  • data: DeviceData

  Returns void

execute

• execute<T extends AnyStorageTransformation>(
      op: T,
      inputs: DeviceData[],
      output?: DeviceData,
  ): Promise<DeviceData>

  Execute a tensor operation

  Dispatches to specific operation implementations based on the operation type.

  Type Parameters

  • T extends AnyStorageTransformation

  Parameters

  • op: T
  • inputs: DeviceData[]
  • Optionaloutput: DeviceData

  Returns Promise<DeviceData>

readData

• readData(data: DeviceData): Promise<ArrayBuffer>

  Read data from CPU memory

  For CPU backend, this returns the buffer directly.

  Parameters

  • data: DeviceData

  Returns Promise<ArrayBuffer>

supportsNonContiguous

• supportsNonContiguous(_op: AllOperationTypes): boolean

  Check if CPU backend supports non-contiguous tensors for a specific operation

  For the CPU demo backend, we don't support non-contiguous tensors for any operations to keep the implementation simple. All operations expect contiguous data.

  Parameters

  • _op: AllOperationTypes

  Returns boolean

writeData

• writeData(data: DeviceData, buffer: ArrayBuffer): Promise<void>

  Write data to CPU memory

  Parameters

  • data: DeviceData
  • buffer: ArrayBuffer

  Returns Promise<void>
