void qrd_householder(input_stream<cfloat>* __restrict matAU_0,
                     input_stream<cfloat>* __restrict matAU_1,
                     output_stream<cfloat>* __restrict matRQ_0,

Note

  • To utilize bandwidth of input / output stream, the input matrix and output result are transfered in such way: Elem[N*4] and Elem[N*4+1] are transferred with matAU_0/matRQ_0, Elem[N*4+2] and Elem[N*4+3] are transferred with matAU_1/matRQ_1.
  • Input:
    • input_stream<cfloat>* matAU_0 stream of input matrix, contains lower two elements of each 4 elements.
    • input_stream<cfloat>* matAU_1 stream of input matrix, contains higher two elements of each 4 elements.
    • column_id column id, the elements below diagonal will be zeroed.
  • Output:
    • input_stream<cfloat>* matRQ_0 stream of output matrix, contains lower two elements of each 4 elements.
    • input_stream<cfloat>* matRQ_1 stream of output matrix, contains higher two elements of each 4 elements.
