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...

The serial communication is very commonly used communicat ion protocol between various peripherals and processor. The current trend is all high speed buses are built with serial communicat ion interface. The ALTERA’s NIOS II soft processor and PowerPC hard processor are widely used in FPGA based CSOC (configurable system on chip) applications. These processers don’t have programmable serial lin...

This paper presents a novel directional median filter based deinterlacing algorithm (DMFD). DMFD is a content adaptive spatial deinterlacing algorithm that finds the direction of the edge and applies the median filtering along the edge to interpolate the odd pixels from the 5 pixels from the upper and 5 pixels from the lower even lines of the field. The proposed algorithm gives a significance i...

This study focuses on accelerating the optimization of motion estimation algorithms, which are widely used in video coding standards, by using both the paradigm based on Altera Custom Instructions as well as the efficient combination of SDRAM and On-Chip memory of Nios II processor. Firstly, a complete code profiling is carried out before the optimization in order to detect time leaking affecti...

This contribution focuses on the optimization of matching-based motion estimation algorithms widely used for video coding standards using an Altera custom instruction-based paradigm and a combination of synchronous dynamic random access memory (SDRAM) with on-chip memory in Nios II processors. A complete profile of the algorithms is achieved before the optimization, which locates code leaks, an...

Elliptic Curve Digital Signature Algorithm (ECDSA) is implemented on an Altera Cyclone II EP2C20F484C7 FPGA using a DE1 development and education board. Digital signatures are digital counterparts of handwritten signatures. They provide proof of authorship and authenticity and they are unforgeable. They also provide proof that the document has not been altered after signing. The design includes...

FPGA devices with embedded DSP and memory blocks, and high-speed interfaces are ideal for real-time video processing applications. In this work, a hardware-software co-design approach is proposed to effectively utilize FPGA features for a prototype of an automated video surveillance system. Time-critical steps of the video surveillance algorithm are designed and implemented in the FPGA’s logic ...
