Original Abstract Submitted

Circuitry for decomposing block floating-point numbers into lower precision floating-point numbers is provided. The circuitry may include a high precision storage circuit configured to provide high precision floating-point numbers, input selectors configured to receive the high precision floating-point numbers from the high precision storage circuit and to generate corresponding lower precision floating-point components with adjusted exponents, and a low precision block floating-point vector circuit configured to combine the various lower precision floating-point components generated by the input selectors. The lower precision floating-point components may be processed spatially or over multiple iterations over time.
