Hardware-software cosynthesis for digital systems

A Hardware/Software Cosynthesis System for Digital Signal Processor Cores with Two Types of Register Files

In digital signal processing, bit width of intermediate variables should be longer than that of input and output variables in order to execute intermediate operations with high precision. Then a processor core for digital signal processing is required to have two types of register files, one of which is used by input and output variables and the other one is used by intermediate variables. This...

MOGAC: a multiobjective genetic algorithm for hardware-software cosynthesis of distributed embedded systems

In this paper, we present a hardware-software cosynthesis system, called MOGAC, that partitions and schedules embedded system specifications consisting of multiple periodic task graphs. MOGAC synthesizes real-time heterogeneous distributed architectures using an adaptive multiobjective genetic algorithm that can escape local minima. Price and power consumption are optimized while hard real-time...

Software and Hardware Improvements for Digital Solar

SOFTWARE AND HARDWARE IMPROVEMENTS FOR DIGITAL SOLAR MAGNETOGRAPH SYSTEM by Shu Yang Digital solar imaging systems have been widely used in solar observations. Their high resolution, high rate of image acquisition and convenience for off-line image processing have provided significant improvements to solar physics research. In this project, two digital magnetograph systems established at Big Be...

Hardware/Software Co-Reliability of Configurable Digital Systems

This paper investigates on the co-effect of hardware and software on the reliability as measured by quality level (or defect level) of configurable multichip module (CMCM) systems. Hardware architecture of CMCM can be configured to accommodate target application design. An application, as provided in a form of software, is partitioned and mapped on the provided configurable hardware. Granularit...
