Title: Pineapple ONE: homemade 32 bit RISC-V CPU made only out of basic logic components and memories – no FPGA or microcontrollers
Presenter: Filip Szkandera | Higher School and Secondary School of Electrotechnical Engineering in Olomouc, Czech Republic
Bio: Filip Szkandera is a student of Higher Vocational and High School of electrotechnical engineering in Olomouc, Czech Republic. He is interested in electronics, especially in building his own CPU(s).
Filip Szkandera has spent two years creating RISC-V with only individual parts without using FPGA / microcomputer. He piled up eight custom printed circuit boards. He attends the Higher Vocational Electrical Engineering School in Olomouc, Czech Republic. I named it “Pineapple One”.
Inside it’s slick 3D printed case, the Pineapple ONE is packing a home-built RISC-V CPU.
In the early 1980s, I debugged the breadboard of the DMA controller chip for the 68000 by myself. It is an ancient minicomputer with 40 TTL-packed custom boards mounted on a rack. A person who does logic simulation comes about once every three days to correct the logic, so my job is to reflect it on the breadboard by wire wrapping and soldering and think about the test method. When the jumper wire became about 1 cm thick and looked like hair, I decided to make a tip. Three years had passed when I noticed.mDesigning a “Pineapple One” requires talent, independence and guts.
