“…Program threads were also represented as directed graphs. Yen and Wolf [Wolf 1994;Yen and Wolf 1996] considered the codesign of embedded computing systems. Their target design consisted of a hardware engine made up of several processing elements (PE) which could be either CPUs or ASICs and an application software architecture with allocation and scheduling of processes and communication [Yen and Wolf 1995a].…”

“…The current hardware-software codesign researches are all devoted to application-specific systems such as heterogeneous multiprocessor systems [Prakash and Parker 1992], DSP applications [Kalavade and Lee 1993], embedded digital systems [Gupta and De Micheli 1993], UNITY language programs [Barros, Rosentiel, and Xiong 1994], and distributed embedded computing systems [Wolf 1994;Yen and Wolf 1995b, a;Wolf 1996;1997]. Application-specific systems typically require system partitioning into hardware and software parts.…”

“…When software is simultaneously synthesized, it is called cosynthesis or codesign which requires system partitioning, hardwaresoftware tradeoff refinements, and cosimulation. In particular, embedded digital systems and DSP applications are often targets of hardware-software cosynthesis [Wolf 1994;Kalavade and Lee 1993].…”

Currently, a lot of research is devoted to system design, and little work is done on requirements analysis. Besides going from specification to design, one of our main objectives is to show how an application problem can be transformed into specifications. Working from the hardwaresoftware codesign perspective, a system is designed starting from an application problem itself, rather than the detailed behavioral specifications. Given an application problem specified as a directed acyclic graph of elementary problems, a hardware-software solution is derived such that the synthesized software, a parallel pseudoprogram, can be scheduled and executed on the synthesized hardware, a set of system-level parallel computer specifications, with heuristically optimal performance. This is known as system-level cosynthesis of application-oriented general-purpose parallel systems for which a novel methodology called Cosynthesis Methodology for Application-Oriented Parallel Systems (CMAPS), is presented. Since parallel programs and multiprocessor architectures are largely interdependent, CMAPS explores the relationship between hardware designs and software algorithms by interleaving the modeling phases and the synthesis phases of both hardware and software. High scalability in terms of problem complexity and easy upgradability to new technologies are achieved through modularization of the input problem specification, of the software algorithms, and of the hardware subsystem models. The work presented in this paper will be beneficial to designers of general-purpose parallel computer systems which must be oriented toward solving some user-specified problem such as the global controller of an industry automation process or a multiprocessor video server. Some application examples are given to illustrate various codesign phases of CMAPS and its feasibility.

“…separate treatment of hardware and software) do not cope with the complexity of today's embedded systems and the steadily increasing time-to-market pressure. Sloppily speaking, "building a machine and seeing whether it works" is not feasible due to unpredictable design times when heterogeneous applications are getting integrated to create a complex system [23]. A promising approach to deal with the complexity of modern embedded systems is hardware/software co-design, i.e.…”

Abstract. 8-bit microcontrollers like the 8051 still hold a considerable share of the embedded systems market and dominate in the smart card industry. The performance of 8-bit microcontrollers is often too poor for the implementation of public-key cryptography in software. In this paper we present a minimalist hardware accelerator for enabling elliptic curve cryptography (ECC) on an 8051 microcontroller. We demonstrate the importance of removing system-level performance bottlenecks caused by the transfer of operands between hardware accelerator and external RAM. The integration of a small direct memory access (DMA) unit proves vital to exploit the full potential of the hardware accelerator. Our design allows to perform a scalar multiplication over the binary extension field GF(2 191 ) in 118 msec at a clock frequency of 12 MHz. Considering performance and hardware cost, our system compares favorably with previous work on similar 8-bit platforms.

“…The process of concurrently defining the hardware and software portions of an embedded system while considering dependencies between the two is called hardware-software co-design [1]- [4]. Time pressure makes it difficult for an engineer to explore the numerous alternative designs which have the potential to meet a given set of specifications.…”
