High precision arithmetic units for fine-grain massively parallel computing

In this paper we deal with new high precision arithmetic units (AUs). These AUs are specialized in the computation of one arithmetic operation (division, addition, etc.), but when hundreds of them are interconnected by a reconfigurable network, a parallel architecture that uses massive digit-level pipelining between floating-point arithmetic units (allowing fast computation of scientific jobs) becomes interesting. In this paper we present several new AUs for the fast computation of arithmetic expressions that will be used on a high precision massively parallel computer
