Matt VennWant to help build a crowdsourced microcontroller?
You're invited to design peripherals (UARTs, timers, synths, etc.) for a
@risc_v chip that will be fabbed for real!
Take part for free!
✍️ #MorpurgoMedia.nl@matthewvenn But who is we?
@Morpurgo ? Do you mean who is Tiny Tapeout?
@matthewvenn yes, who is bevind all of it.
chrysn@matthewvenn I'm fascinated by this, but never had my hands on HDLs (but plenty MCUs). Maybe it'd be clear from the templates, but what do these modules get except area and their SPI access? Do they get raw outside pins, or pin access muxed onto a GPIO buffer? Do they get a clock signal (other than SCK)? Is SPI easier to do than mapping the peripheral into a memory bus?
@matthewvenn The FAQ of tinytapeout answer some of that, but it sounds more like those relate to building custom chips, while the present RISCV challenge would all wind up in one MCU?
Mike Bell@chrysn @matthewvenn The peripherals in the RISC-V challenge will end up in an MCU that will be one design on the Tiny Tapeout chip.
Each peripheral gets a range of memory addresses, and access to the 8 input and 8 output pins. The interface is here: https://github.com/TinyTapeout/tinyqv-byte-peripheral-template/blob/main/src/peripheral.v#L11L27

Sahil@matthewvenn @risc_v good morning, this is awesome! Does it cost millions to make? I ask as a parent who would love for his childs school and or college to run this kind of collaborative/competition for students to learn about hardware.
@Sahil_n05 Thanks!
We're taping out with ChipFoundry, which is $15k for 100 chips.
As we split the cost between all the projects on the chip, it usually costs about €300 per chip.
But entering the contest is free!
@matthewvenn thanks for replying. I wouldn't know where to start to design a chip, I leaned about processors as part of computer science but that's it. Can't wait to see what you all get.
