چکیده

This paper presents methods based on the formalism of aane recurrence equations for the synthesis of bit-level regular architectures from word-level (integer or real) algorithms. Because of bit-level dependency analysis, the arrays have optimal eeciency. We present two possible design ows leading to architectures based either on bit-parallel or bit-serial operators. The rst one is fully automated.

Implementation and Comparison of Vedic Multiplier using Area Efficient CSLA Architectures

In the design of Integrated circuits, area plays a vital role because of increasing the necessity of portable systems. Carry Select Adder (CSLA) is a fast adder used in many dataprocessing processors for performing fast arithmetic functions. From the structure of the CSLA, the scope is reducing the area of CSLA based on the efficient gate-level modification. In this paper 4 bit, 8 bit, 16 bit, ...

Libraries of schedule-free operators in Alpha

This paper presents a method, based on the formalism of affine recurrence equations, for the synthesis of digital circuits exploiting parallelism at the bit-level. In the initial specification of a numerical algorithm, the arithmetic operators are replaced with their yet unscheduled (schedule-free) binary implementation as recurrence equations. This allows a bit-level dependency analysis yieldi...

High-level Synthesis of Scalable Architectures for Iir Filters Using Parameterized Mcm's

We describe the high-level synthesis of scalable 1 parallel architectures implementing in niteimpulse response (IIR) lters using multi-chip module (MCM). Our approach is based on a new class of parallel schedules for computing mth-order IIR lters, called regular schedules. The simplicity of the regular schedules facilitates characterization of their inter-processor communications, which is gene...
