👾 Oh, you designed a CPU in #Verilog for a calculator? How groundbreaking! 🚀 Next, maybe try inventing the wheel in Python while you're at it. 🛞🔄 Spoiler alert: the world already solved this in the 80s. 📟💾

RISC-V: Kiến trúc bộ lệnh RISC mở, đơn giản hóa đe dọa ARM/x86 bằng cách:
• Sử dụng nền tảng modun (RV32I/RV64I) + mở rộng tùy chọn (M,A,F,D,C)
• Linh hoạt cho chip nhỏ đến hệ thống Linux đầy đủ
• Hỗ trợ Linux native, lý tưởng cho IoT & phần cứng tùy chỉnh
• Thành công nhờ tiếp cận từng bước & thiết kế bền vững

🐢🎉 Behold! A blog about building a CPU as slow as molasses in January! They’ve successfully made two programs work (cue applause): a pixelated petri dish and a psychedelic mess. But wait, there's more: 🎇The display explodes into random junk if you dare to send data faster than a snail's pace! Clearly, the future of computing is in very safe, albeit very slow, hands. 🐌💻

After getting a basic ALU design done yesterday & starting a **very** rough start at a microcodeish thing, today the first design of the controlunit & overall cpu design comes together, so it can actually calculate an addition from two arbitary registers and store the result back into a register of choice! :3

Still a lot to go but excited it works already somewhat! #hardware #fantasyconsole #diy #verilog #systemverilog #software #cpudesign #hardwaredesign #fpga #fpgadev

Baby steps in getting my Apple I reproduction PCB up and running. 6502 CPU booting with just RAM and ROM attached. It grabs the reset address from ROM and starts executing code...until it tries to do something with IO, which is not attached yet...

I'm monitoring the bus with an Arduino MEGA attached to my MacBook Pro.

Does anyone know if little-endian has any technical advantages? Big-endian machines are all but extinct these days (outside of IBM mainframes).
Or is is just a case of having to pick one and stick with it, like how all life on Earth is made out of L-chiral amino acids and D-chiral carbohydrates?
