Custom Fpga Cryptographic Blocks for Reconfigurable Embedded Nios Processor

This paper introduces two custom blocks for Nios reconfigurable embedded processor implemented on Altera Field Programmable Gate Arrays (FPGAs). When operations like modular multiplication and modular exponentiation of long integers or other complex algebraic functions are performed on a general-purpose processor they usually consume a lot of processor resources and execution times are not sati...

A Real-Time Marker-Based Visual Sensor Based on a FPGA and a Soft Core Processor

This paper introduces a real-time marker-based visual sensor architecture for mobile robot localization and navigation. A hardware acceleration architecture for post video processing system was implemented on a field-programmable gate array (FPGA). The pose calculation algorithm was implemented in a System on Chip (SoC) with an Altera Nios II soft-core processor. For every frame, single pass im...
