A comparison of microcontrollers targeted to FPGA-based embeddedapplications

摘要

There is available today a large amount of microcontroller coresto the embedded market, ranging from classical architectures like the8051 to RISC or DSP machines. The choice among different architecturesdepends of parameters like speed, power installed base, amount ofpossible reuse and other technical issues. This paper will make acomparison of 3 different architectures targeted to FPGA-based systems.Our main contribution is the development of a Java ASIP microcontroller,which allows good area-speed compromise, while maintaining low softwaredevelopment costs, which are ever increasing for embedded systems
