Analysis of floating point operations in microcontrollers

2011 Proceedings of IEEE Southeastcon, 2011
The purpose of this paper is to identify the advantages of including a floating point hardware / a mathematical co-processor in microcontrollers used for critical floating point operations. Three different microcontrollers are considered: Renesas M16C/62P (CISC without FPU), ATMEGA1280 (RISC without MCU) and Renesas RX62N (CISC with FPU).

Accelerating Microblaze Floating Point Operations

2007 International Conference on Field Programmable Logic and Applications, 2007
The MicroBlaze processor serves in many FPGA designs as the central 32 bit CPU with access to the global off chip memory and peripherals. MicroBlaze provides FSL links for up to 8 coprocessors. We present two MicroBlaze designs. The first design works with 8 PicoBlaze-based accelerators for pipelined, single-precision floating point vector-oriented ...

Semantics for exact floating point operations

[1991] Proceedings 10th IEEE Symposium on Computer Arithmetic, 2002
Semantics are given for the four elementary arithmetic operations and the square root, to characterize what are termed exact floating point operations. The operands of the arithmetic operations and the argument of the square root are all floating point numbers in one format.

Accurate floating-point operation using controlled floating-point precision

Proceedings of 2011 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing, 2011
Rounding and accumulation of errors when using floating point numbers are important factors in computer arithmetic. Many applications suffer from these problems. The underlying machine architecture and representation of floating point numbers play the major role in the level and value of errors in this type of calculations.

Formalization and implementation of floating-point matrix operations

Computing, 1976
The paper shows that floating-point matrix operations can be implemented in a way which leads to reasonable mathematical structures as well as to sensible compatibility properties between these structures and the structure of the real matrices. It turns out, for instance, that all the rules of the minus-operator for real matrices can be saved and that ...

An accelerator for double precision floating point operations

Eleventh Euromicro Conference on Parallel, Distributed and Network-Based Processing, 2003. Proceedings., 2003
We describe DPFPA (double precision floating point accelerator) an FPGA based coprocessor interfaced to the CPU through the PCI bus; it is conceived to accelerate the evaluation of double precision floating point operations. This coprocessor is based on two double precision floating point units: a pipelined adder and a pipelined multiplier. The work is

Improving the ratio of memory operations to floating-point operations in loops

ACM Transactions on Programming Languages and Systems, 1994
Over the past decade, microprocessor design strategies have focused on increasing the computational power on a single chip. Because computations often require more data from cache per floating-point operation than a machine can deliver and because operations are pipelined, idle computational cycles are common when scientific applications are executed ...

VHDL Floating Point Operations

1995
In this paper, we present a set of portable floating point VHDL functions. These functions provide the VHDL programmer with absolute portability and very precise control over floating point operations. A single VHDL type is used to represent single, double, and extended precision floating point numbers.

Parameterisable floating-point operations on FPGA

Conference Record of the Thirty-Sixth Asilomar Conference on Signals, Systems and Computers, 2002., 2003
The paper presents a group of IEEE 754-style floating-point units targeted at Xilinx VirtexII FPGA. Special features of the technology are taken advantage of to produce optimised components. Pipelined designs are given that show the latency of /spl sim/100 MHz single-precision components.
