Introduction μP on FPGAs? Today’s FPGAs will not be able to implement such a top-of-the-range μP (Intel) with a single FPGA. But there are many applications where a less- powerful μP can be quite helpful. In software, or when designed as an FSM, an algorithm like an FFT may ran slower, but usually needs much less resources. So the μP we build with FPGAs are more of the microcontroller type than a fully featured modern Intel. You may argue that this can be done with an FSM.
Introduction μP on FPGAs? The early version of Xilinx PicoBlaze processor = (KCPSM) Ken Chapman programmable state machine
Introduction A complete μP design usually involves several steps, such as the architecture exploration phase, the instruction set design, and the development tools.
Types of Microprocessors Usually microprocessor are classified into three major classes: General-Purpose Microprocessors or CISC RISC Microprocessors PDSPs
General-Purpose Microprocessors Usually based on CISC (Complex Instruction Set Computer)
