In this work, we present a radix-10 division unit that is based on the digit-recurrence algorithm and implements binary encodings (binary integer decimal or BID) for significands. Recent decimal division designs are all based on the binary coded decimal (BCD) encoding. We adapt the radix-10 digit-recurrence algorithm to BID representation and implement the division unit in standard cell technology...
In this paper we deal with the throughput of on-line addition for a stream of data. This throughput is directly related to the initiation interval between two successive instances. The on-line delay for the addition of two signed-digit (or carry-save) numbers is two, and N+2 cycles are classically used to compute a new pair of N- digit data (initiation interval: N+2). In this paper we present some...
In this paper, we propose a class of division algorithms with the aim of reducing the delay of the selection of the quotient digit by introducing more concurrency and flexibility in its computation. From the proposed class of algorithms, we select one that moves part of the selection function out of the critical path, with a corresponding reduction in the critical path compared with existing alternatives:...
