Software Design of A Cost/Performance Estimation Method for Hardware/Software PartitioningHuang, Yau-Shian 01 October 2001 (has links)
In the age of deep submicron VLSI, we can design various system applications in a single chip. On this system-on-chip design, there are ASIC circuitry, processor core together with software components, and hardware modules. During system design, we need to select the forms of execution for kinds of system functions.It is called hardware/software partitioning. Different hardware/software partitioning, affect the achievable cost and performance of the accordingly elaborated system chip designs.
In this research, we explore research and software design issues of an estimation method for hardware/software partitioning. It consists of these tasks:
¡Esoftware scheduling
¡Ehardware/software co-scheduling
¡Ecost and performance estimation for
hardware/software partitioning
For a system description, given a chosen hardware/software partitioning and a set of allocated resources, we can perform the corresponding cost and performance estimation task that can be utilized directly by system designs or can be called by a hardware/software partitioning optimization program. We designed the experimental software for this estimation method. We also carried out a set of experiments based upon real and synthesized design cases.

Towards An Automated Approach to Hardware/Software DecompositionQin, Shengchao, He, Jifeng, Chin, Wei Ngan 01 1900 (has links)
We propose in this paper an algebraic approach to hard-ware/software partitioning in Verilog Hardware Description Language (HDL). We explore a collection of algebraic laws for Verilog programs, from which we design a set of syntax-based algebraic rules to conduct hardware/software partitioning. The co-specification language and the target hardware and software description languages are specific subsets of Verilog. Through this, we confirm successful verification for the correctness of the partitioning process by an algebra of Verilog. Facilitated by Verilog’s rich features, we have also successfully studied hw/sw partitioning for environment-driven systems. / Singapore-MIT Alliance (SMA)

Design and Implementation of SoC Hardware-Software Co-design PlatformLeong, Mun-kit 14 February 2008 (has links)
Reconfigurable supercomputing has been used by many high-performance computer systems to accelerate the processing speed. Thus, it is the present trend to use the microprocessor to combine with reconfigurable FPGA as the embedded system platform. However, the hardware-software co-design and integration of embedded system become great challenges of the designer. Beside this, the communication between hardware and software is crucial for the system to be operated effectively. Our concept consists of the design of FPGA configuration, described in I-Link hardware/software integration, improve the communication among the hardware and software. Besides, by using command packet method, we put the data to multi-hardware through hardware management unit (HMU). While system is operated, The Boot Loader will set up TCB and HCB data structure through PSP. The PSP can be regarded as the important reference segment of messages switching among system and hardware/software. The HMU has data buffering and management ability which can let the processes more easy and smooth. We successfully accomplish a hardware-software integrated system in HSCP, which is developed in our laboratory. The basic components of our platform include ARM7TDMI CPU, memory and Altera ACEK 1K-100 of FPGA. By using ARM-code, we also preliminary accomplish the Boot Loader, HW Constructor and self-developed embedded system. Finally, we make use of a large amount of multiplication operation and matrix summation to verify the feasibility of this system architecture.

Simulation Framework of embedded systems in armored vehicle design / Simuleringsramverk av inbyggda system i bandvagnsdesignBergström, Christoffer January 2021 (has links)
Embedded systems are a mixture of electric and mechanical hardware along with the software that is controlling them. BAE Systems Hägglunds, which designs and builds armored vehicles, is interested in knowing how to simulate these systems for logic validation and testing different design variations. The goal of this thesis was to create a framework for carrying out these simulations. This was done by analyzing hardware and software design at BAE and Identifying the necessary conditions for creating a model which can be simulated. Matlab Simulink is suggested as the tool for these simulations. The framework suggests dividing the model into smaller modules which reflects design principles at BAE. These modules will be made up of sub-modules containing hardware and software in layers. The hardware foundation will be made up of pre-designed components created in Simulink’s physical simulation library. The software will be imported into specialized sub-modules and integrated into the hardware using proposed bridge functions, converting information between the two systems. The framework is designed to provide a comprehensive solution instead of a deep one that can be adapted to changing circumstances. Tests have been made on small-scale systems, but the framework still needs to be tested on a large-scale system, which was not possible during this thesis. In conclusion, this is a stable foundation that needs to be built upon.

Low-cost Hardware Profiling of Run-time and Energy in FPGA Soft ProcessorsAldham, Mark 11 August 2011 (has links)
Field Programmable Gate Arrays (FPGAs) are a reconfigurable hardware platform which enable the acceleration of software code through the use of custom-hardware circuits. Complex systems combining processors with programmable logic require partitioning to decide which code segments to accelerate. This thesis provides tools to help determine which software code sections would most benefit from hardware acceleration.
A low-overhead profiling architecture, called LEAP, is proposed to attain real-time profiles of an FPGA-based processor. LEAP is designed to be extensible for a variety of profiling tasks, three of which are investigated and implemented to identify candidate software for acceleration. 1) Cycle profiling determines the most time-consuming functions to maximize speedup. 2) Cache stall profiling detects memory-intensive code; large memory overheads reduce the benefits of acceleration. 3) Energy consumption profiling detects energy-inefficient code through the use of an instruction-level power database to minimize the system's energy consumption.
