A software-hardware cosynthesis approach to digital system simulation

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...

The JavaTime Approach to Mixed Hardware-Software System Design

"What has been is what will be, and what has been done is what will be done, and there is nothing new under the sun." Abstract We describe an approach for using Java as a basis for a design and specification language for embedded systems and use our JavaTime system to illustrate many of the aspects of the approach. Java is a pragmatic choice for several reasons. Since it is a member of the C " ...

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...
