US Patent 7849283 Linear combiner weight memory

A linear combiner weight memory. Various embodiments of the weight memory provide a weight bank and control logic. The weight bank is operable to couple with a data stream and may include four registers. The first register is operable to store a first in-phase weight value. The second register is operable to store a second in-phase weight value and be written with the second in-phase weight value while the first in-phase weight value is read from the first register. The third register is operable to store a first quadrature weight value. The fourth register is operable to store a second quadrature weight value and be written with the second quadrature weight value while the first quadrature weight value is read from the third register.
