Soft Cores vs Hard Cores Embedded processor hard-core FPGAs, also known as SoC FPGAs, integrate hard-core processors into the hardware design from the outset, allowing for pure hardware implementation without consuming FPGA logic resources. The hard-core processor and FPGA logic are largely independent of each other. In simple terms, SoC FPGAs combine an ARM processor … Read more
