Definition

Namespace:
Android.Renderscripts
Assembly:
Mono.Android.dll

8-bit GEMM-like operation for neural networks: C = A * Transpose(B) Calculations are done in 1.

[Android.Runtime.Register("BNNM", "(Landroid/renderscript/Allocation;ILandroid/renderscript/Allocation;ILandroid/renderscript/Allocation;II)V", "", ApiSince=23)]
public void BNNM (Android.Renderscripts.Allocation? A, int a_offset, Android.Renderscripts.Allocation? B, int b_offset, Android.Renderscripts.Allocation? C, int c_offset, int c_mult);
[<Android.Runtime.Register("BNNM", "(Landroid/renderscript/Allocation;ILandroid/renderscript/Allocation;ILandroid/renderscript/Allocation;II)V", "", ApiSince=23)>]
member this.BNNM : Android.Renderscripts.Allocation * int * Android.Renderscripts.Allocation * int * Android.Renderscripts.Allocation * int * int -> unit

Parameters

A
Allocation

The input allocation contains matrix A, supported elements type Element#U8.

a_offset
Int32

The offset for all values in matrix A, e.g A[i,j] = A[i,j] - a_offset. Value should be from 0 to 255.

B
Allocation

The input allocation contains matrix B, supported elements type Element#U8.

b_offset
Int32

The offset for all values in matrix B, e.g B[i,j] = B[i,j] - b_offset. Value should be from 0 to 255.

C
Allocation

The input allocation contains matrix C, supported elements type Element#U8.

c_offset
Int32

The offset for all values in matrix C.

c_mult
Int32

The multiplier for all values in matrix C, e.g C[i,j] = (C[i,j] + c_offset) * c_mult.

Remarks

8-bit GEMM-like operation for neural networks: C = A * Transpose(B) Calculations are done in 1.10.21 fixed-point format for the final output, just before there's a shift down to drop the fractional parts. The output values are gated to 0 to 255 to fit in a byte, but the 10-bit format gives some headroom to avoid wrapping around on small overflows.
