摘要:Embedded system design is becoming complex day by day, combined with reduced time-to-market deadlines. Due to the constraints and complexity in the design of embedded systems, it incorporates hardware / software co-design methodology. An embedded system is a combination of hardware and software parts integrated together on a common platform. A soft-core processor which is a hardware description language (HDL) model of a specific processor (CPU) can be customized for any application and can be synthesized for FPGA target. This paper gives a comparative analysis of the development environment for embedded systems using LEON 3 and NIOS II Processor, both soft core processors. LEON3 is an open source processor and NIOS II is a commercial processor. Case study under consideration is Rijindael's Encryption Algorithm (AES). It is a standard encryption algorithm used to encrypt huge bulk of data and for security. Using the co-design methodology the algorithm is implemented on two different platforms. One using the open source and other using the commercial processor and the comparative results of the two different platforms is stated in terms of its performance parameters. The algorithm is partitioned in hardware and software parts and integrated on a common platform.
