چکیده

This paper presents the design of a new bit-serial floating-point unit (FPU). It has been developed for the processors of the Instruction Systolic Array parallel computer model. In contrast to conventional bit-parallel FPUs the bit-serial approach requires different data formats. Our FPU uses an IEEE compliant internal floating point format that allows a fast least significant bit (LSB)-first arithmetic and can be efficiently implemented in hardware.

Design and Implementation of a High Speed Systolic Serial Multiplier and Squarer for Long Unsigned Integer Using VHDL

A systolic serial multiplier for unsigned numbers is presented which operates without zero words inserted between successive data words, outputs the full product and has only one clock cycle latency. &#10The multiplier is based on a modified serial/parallel scheme with two adjacent multiplier cells. Systolic concept is a well-known means of intensive computational task through replication of fu...

Design and Implementation of an Efficient Programmable Floating Point Unit with Coarse - Grained FPGA Arun

The novel method is to optimize coarse-grained floating point units (FPUs) in a hybrid FPGA by employing common sub graph extraction to determine the number of floating point adders / subtracters (FAs), multipliers (FMs) and word blocks (WBs) in the FPUs. Single precision FP adders / subtracters (FAs) and FP multipliers (FMs), with normalization are generated using standard cell library design ...

Method for Ultra-precision FPU Integration based on Fine-Grained Control

In general, the FPU and processor are decoupled in the method for FPU integration, in which the communication between them requires software intervention and ultra-precision FPU is unsupported. To avoid this problem, a method based on fine-grained control for integration of FPU into the RISC processor is proposed in this paper. In terms of operand width of floating-point instructions, the metho...
