This work presents the custom-made design of a 32-bit fixed-point trigonometric computer based on the CORDIC (Coordinate Rotation Digital Computer) algorithm and embedded in an AT94K40 system-on-chip device. This platform –composed of a 8-bit MCU that handles the program flow and a dynamically reconfigurable FPGA that synthesizes an evolvable slave(More)
Complex algorithms usually require several computation stages. Many embedded microprocessors have not enough computational performance to resolve these algorithms in a reasonable time, so dedicated coprocessors accelerate them although the main drawback is the area devoted to them. A reconfigurable coprocessor can drastically reduce the area, since it(More)
This work aims to pave the way for an efficient open system architecture applied to embedded electronic applications to manage the processing of computationally complex algorithms at real-time and low-cost. The target is to define a standard architecture able to enhance the performance-cost trade-off delivered by other alternatives nowadays in the market(More)
