Detailed Description

A framework to accelerate Quantized multiplication in Synet Framework.

Function Documentation

SimdSynetQuantizedMulForward()

void SimdSynetQuantizedMulForward	(	void *	context,
		const uint8_t *	a,
		const uint8_t *	b,
		uint8_t *	dst
	)

Performs element-wise quantized multiplication.

Algorithm's details for UINT8 output:

for(i = 0; i < size; ++i)
{
    _a = (a[i] - aZero)*aScale;
    _b = (b[i] - bZero)*bScale;
    dst[i] = RestrictRange(Round((_a * _b)/dstScale) + dstZero, 0, 255);
}

Parameters

[in]	context	- a pointer to quantized multiplication context. It must be created by function SimdSynetQuantizedMulInit and released by function SimdRelease.
[in]	a	- a pointer to input A tensor data. Its type is defined by parameter aType of SimdSynetQuantizedMulInit.
[in]	b	- a pointer to input B tensor data. Its type is defined by parameter bType of SimdSynetQuantizedMulInit.
[out]	dst	- a pointer to output tensor data. Its type is defined by parameter dstType of SimdSynetQuantizedMulInit.
