PT13 - Compact microprocessor for Altera FPGAs
A compact microprocessor for Altera (Intel) FPGAs that we designed for use in our products and is available as a free download. The design uses less than 400 logic elements allowing multiple instantiations in the same FPGA. The assembler automatically generates a MIF file which can be compiled after a code change into a small single-port ROM. PT13 is ideal for simple control operations, display control, I2C initialisation of devices etc.
