Abstract: A new operation model of flexible calculation that allows us to adjust the operation delay depending on the available time is presented. The operation method design uses look-up tables and progressive construction of the result. The increase in the operators’ granularity opens up new possibilities in calculation methods and microprocessor design. This methodology, together with the advances in technology, enables the functions of an arithmetic unit to be implemented on the basis of techniques based on stored data that provide quality results and systematization in the implementation. The proposed techniques are applied in the design of a multiplier operator. We report an evaluation of the architecture in area, delay and computation error, as well as a suitable implementation of an application example in FPGA to validate the design.
