Using RV32E + high registers for access to GPIOs and FIFOs is genius.\nAs bunnie says it would be good to get higher CPI, and I think including the B extension would make sense given the kind of work the core will be doing. I might start from FemtoRV, the smallest version can do 2 CPI for most instructions - though I suspect PicoRV has a higher fmax.\nIf I was doing an implementation for gf180, I\u2019d use two SRAM blocks for instruction memory, to give 16 bit access per clock, matching 2 CPI - I already have a wrapper around FemtoRV that does this for my RV4028 project. Only 13 registers are needed (gp and tp can be dropped like TinyQV does) so those can be implemented in latches.", "author": { "id": "691780627338625077", "name": "rebelmike", "discriminator": "0000", "nickname": "RebelMike", "color": null, "isBot": false, "roles": [], "avatarUrl": "2026-03_media/49aaff687e56f04e7bbdedf0077bab75-7DDB4.png" }, "attachments": [], "embeds": [], "stickers": [], "reactions": [], "mentions": [], "inlineEmojis": [] }, { "id": "1485565713992253472", "type": "Default", "timestamp": "2026-03-23T09:07:46.692+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "Would be cool to make a SoC with 2 or 4 of those plus maybe Hazard3 as the big core!", "author": { "id": "691780627338625077", "name": "rebelmike", "discriminator": "0000", "nickname": "RebelMike", "color": null, "isBot": false, "roles": [], "avatarUrl": "2026-03_media/49aaff687e56f04e7bbdedf0077bab75-7DDB4.png" }, "attachments": [], "embeds": [], "stickers": [], "reactions": [], "mentions": [], "inlineEmojis": [] }, { "id": "1485625756062060605", "type": "Default", "timestamp": "2026-03-23T13:06:21.837+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "Does BIO use the top of the instruction memory for the processors stack?\nRegardless, I think that would make sense for this implementation, and would mean ra and sp could be restricted width as they only need to address that small RAM block (and they should always be word aligned).
