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 |
|
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. |
