weighted_sum − convert a group of bits to an integer
loadrt weighted_sum wsum_sizes=size[,size,...]
Creates weighted sum groups each with the given number of input bits (size).
This component is a "weighted summer": Its output is the offset plus the sum of the weight of each TRUE input bit. The default value for each weight is 2^n where n is the bit number. This results in a binary to unsigned conversion.
There is a limit of 8 weighted summers and each may have up to 16 input bits.
process_wsums (requires a floating point thread)
Read all input values and update all output values.
wsum.N.bit.M.in bit in
The m’th input of weighted summer n.
wsum.N.hold bit in
When TRUE, the sum output does not change. When FALSE, the sum output tracks the bit inputs according to the weights and offset.
wsum.N.sum signed out
The output of the weighted summer
wsum.N.bit.M.weight signed rw
The weight of the m’th input of weighted summer n. The default value is 2^m.
wsum.N.offset signed rw
The offset is added to the weights corresponding to all TRUE inputs to give the final sum.
