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...
This paper presents a new constraint-driven method for computational pattern selection, mapping and application scheduling using reconfigurable processor extensions. The presented method is a part of DURASE system (Generic Environment for Design and Utilization of Reconfigurable Application-Specific Processors Extensions). The selected processor extensions are implemented as specialized processor...
The Cell processor consists of a general-purpose core and eight cores with a complete SIMD instruction set. Although originally designed for multimedia and gaming, it is currently being used for a much broader range of applications.In this paper we evaluate if the Cell SPEs could benefit significantly from a scalar processing unit using two methodologies. In the first methodology the scalar processing...
We present a design and implementation of a radix-4 complex division unit with prescaling of the operands. Specifically, we extend the treatment of the residual bound and errors due to the use of truncated redundant representation. The requirements for prescaling tables are simplified and a detailed specification of the table design is given. All principal components used in the design are described...
There is a clear trend towards multi-cores to meet the performance requirements of emerging and future applications. A different way to scale performance is, however, to specialize the cores for specific application domains. This option is especially attractive for low-cost embedded systems where less silicon area directly translates to less cost. We propose architectural enhancements to specialize...
