◆ vector_mul()

template<typename InType1 , typename InType2 , typename OutType , unsigned int VectorLength, bool Unroll>

void nvhls::vector_mul	(	nv_scvector< InType1, VectorLength >	in1,
		nv_scvector< InType2, VectorLength >	in2,
		nv_scvector< OutType, VectorLength > &	out
	)

Function implementing vector multiplication.

Template Parameters

InType1	Input1 Scalar Type
InType2	Input2 Scalar Type
OutType	Output Scalar Type
VectorLength	Length of vector
Unroll	Template parameter to control unrolling

Overview: This function multiplies two input vectors of InType1 and InType2 type and produces output of type OutType. Length of all vectors is VectorLength. If InType1, InType2, OutType are user-defined types, then OutType = InType1*InType2 should be defined by the user using operator overloading

A Simple Example: #include <nvhls_vector.h>

...

nv_scvector<NVUINT2, 8> v1, v2;

nv_scvector<NVUINT4, 8> out;

...

nvhls::vector_mul<NVUINT2, NVUINT2, NVUINT4, 8, true>(v1,v2,out);

◆ vector_add()

template<typename InType1 , typename InType2 , typename OutType , unsigned int VectorLength, bool Unroll>

void nvhls::vector_add	(	nv_scvector< InType1, VectorLength >	in1,
		nv_scvector< InType2, VectorLength >	in2,
		nv_scvector< OutType, VectorLength > &	out
	)

Function implementing vector addition.

Template Parameters

InType1	Input1 Scalar Type
InType2	Input2 Scalar Type
OutType	Output Scalar Type
VectorLength	Length of vector
Unroll	Template parameter to control unrolling

Overview: This function adds two input vectors of InType1 and InType2 type and produces output of type OutType. Length of all vectors is VectorLength. If InType1, InType2, OutType are user-defined types, then OutType = InType1+InType2 should be defined by the user using operator overloading

A Simple Example: #include <nvhls_vector.h>

...

nv_scvector<NVUINT2, 8> v1, v2;

nv_scvector<NVUINT3, 8> out;

...

nvhls::vector_add<NVUINT2, NVUINT2, NVUINT3, 8, true>(v1,v2,out);

◆ vector_sub()

template<typename InType1 , typename InType2 , typename OutType , unsigned int VectorLength, bool Unroll>

void nvhls::vector_sub	(	nv_scvector< InType1, VectorLength >	in1,
		nv_scvector< InType2, VectorLength >	in2,
		nv_scvector< OutType, VectorLength > &	out
	)

Function implementing vector subtraction.

Template Parameters

InType1	Input1 Scalar Type
InType2	Input2 Scalar Type
OutType	Output Scalar Type
VectorLength	Length of vector
Unroll	Template parameter to control unrolling

Overview: This function adds two input vectors of InType1 and InType2 type and produces output of type OutType. Length of all vectors is VectorLength. If InType1, InType2, OutType are user-defined types, then OutType = InType1-InType2 should be defined by the user using operator overloading

A Simple Example: #include <nvhls_vector.h>

...

nv_scvector<NVUINT2, 8> v1, v2;

nv_scvector<NVINT3, 8> out;

...

nvhls::vector_sub<NVUINT2, NVUINT2, NVINT3, 8, true>(v1,v2,out);

◆ reduction()

template<typename InType , typename OutType , unsigned int VectorLength, bool UseReduceTree>

void nvhls::reduction	(	nv_scvector< InType, VectorLength >	in,
		OutType &	out
	)

Function implementing vector reduction.

Template Parameters

InType	Input Scalar Type
OutType	Output Scalar Type
VectorLength	Length of vector
UseReduceTree	Template parameter to control datapath optimization by HLS tool

Overview: This function performs redcution of input vector of type InType and produces scalar output of type OutType. Length of all vectors is VectorLength. If InType and OutType, OutType are user-defined types, then OutType += InType, OutType = InType should be defined by the user using operator overloading

A Simple Example: #include <nvhls_vector.h>

...

nv_scvector<NVUINT2, 8> v1;

NVUINT5 out;

...

nvhls::reduction<NVUINT2, NVUINT5, 8, true>(v1,out);

◆ dp()

template<typename InType1 , typename InType2 , typename OutType , unsigned int VectorLength, bool UseReduceTree>

void nvhls::dp	(	nv_scvector< InType1, VectorLength >	in1,
		nv_scvector< InType2, VectorLength >	in2,
		OutType &	out
	)

Function implementing vector dot-product.

Template Parameters

InType1	Input1 Scalar Type
InType2	Input2 Scalar Type
OutType	Output Scalar Type
VectorLength	Length of vector
UseReduceTree	Template parameter to control datapath optimization by HLS tool

Overview: This function performs dot-product of 2 input vectors of "InType1" and "InType2" types and produces output of type "OutType". Input vector length is "VectorLength". If InType1, InType2, and OutType are user-defined types, then OutType += InType1*InType2, OutType = InType1*InType2 operations should be defined by the user

A Simple Example: #include <nvhls_vector.h>

...

nv_scvector<NVUINT2, 8> v1, v2;

NVUINT7 out;

...

nvhls::dp<NVUINT2, NVUINT2, NVUINT7, 8, true>(v1, v2, out);
