MicroCore Labs was founded in 2015 and is based in Northern California, USA. Our goal is to develop ultra-small footprint, microsequencer based processor cores which can be implemented in any FPGA or ASIC technology. Our newest product is the MCL51 8051 core which is 100% instruction-set compatible and consumes around 300 Xilinx LUTs. Our MCL86 is a cycle compatible soft IP core of the popular 16-bit 8088/8086 microprocessors which consumes less than one percent of a Kintex-7 FPGA and less than ten percent of a Lattice XO2-7000 FPGA. Future processor cores are in development which will also be ultra-small implementations of popular instruction sets.
