Honestly as someone who spent last year studying different CPUs and ISAs, for me it looks more like old CISC rather than RISC. From my experience, it's normal for RISC to have lots of register (usually between 16 and 32), no direct stack or memory manipulation, only with load/store. Also RISC CPUs (again from my experience) literally always have fixed size instructions. So it looks more like MISC ISA. Still very cool and educational project though!
@direct3d2 ай бұрын
just to let you know, there are actually RISC architectures that have variable instruction lengths, like RISC-V, ARC and blackfin! it's not really a true requirement to label something as RISC or not, just a design choice that happens to work out well for a lot of RISC architectures nonetheless. but i agree, the lots of registers is very traditionally RISC
@kala-telo2 ай бұрын
@@direct3d I forgot about compressed extension, even though I've specifically deeply looked into RISC-V 😅 If that's what you meant. Still, in my opinion, compressed ISA has same size no matter what's instruction it is, while this Excel ISA, and CISC instructions can have differently sized instruction depending on argument size. Also I don't really know about strict definitions, my comments are based on how I felt rather than formal rules.
@GRAYgauss2 ай бұрын
@@direct3d Personally, it's an old intuition from building toy CPUs, but I practically categorize CISC and RISC based on fabrication cost & complexity. VLA greatly complicates control hardware, for example in branch prediction and cache management given it necessitates decoding to determine instruction bounds. It's my intuition that RISC generally simplifies the core pipeline as much as possible, and you see that reflected in chips costs. Looking up RISC-V's C extension, feeling the same as kala-telo, the manual itself says implementers can simply expand compressed instructions to full length form before execution - which is exactly what I would expect to keep hardware as simple as possible. (Also found some FOSS RISC impls with expansion logic) Having many registers to make up for the otherwise simplified core ISA makes perfect sense to me, it's less of a given spec and more of a natural requirement.

I've noticed several youtubers making very simple computers tend to still have ALU flags. This is actually not even necessary! You can perform simple comparison operations instead. For example, in RISC-V you have branch instructions for equals, not equals, etc., and you have an ALU operation to set a register to the boolean value of a less than comparison. You can actually make things like overflow checking using these simple instructions. Keep in mind that there is actually only one opcode for ALU and one for branching, all the rest is done via a few extra bits. There are even a bunch of convenience pseudoinstructions like SEQZ or BEQZ (to check if a register is zero for example), so that it still feels as if you have all the comparison operators

I have an interesting ultra-reduced instruction set, the MCPU instruction set! I've built in in LogiSim, Digital, and recently in Minecraft. Fundamentally, it has only 2 instruction types, and 3 fundamental instructions: (conditional) move(MOV/CMOV) and shift/load immediate value(IMM). It's basically a simple TTA-like design, in the sense that the program counter is just like every other register on the bus, so is the current RAM address, the ALU, and the immediate register. It requires no general-purpose registers(but has space for up to 3 in it's instruction set). One cool feature of my design is that this 8-bit fixed-size instruction set works with any bus-width, even with the same program, by using the IMM instruction to shift in a larger immediate value 7 bits at a time. It's convenient to program as well, the assembler still feels familiar and not like a turing tarpit! The complete instruction set is so simple, it fits in the remainder of this comment: If the highest bit is set, the instruction is an IMM instruction. Remaining bytes are loaded into SRG_IMM register on first instruction, or shifted in on successive instructions. Otherwise, if the second highest bit is set, the instruction is a conditional move(CMOV) and only runs if the ALU flag output is set, if not set it's a regular move(MOV) and always runs. Remaining bits are a 3-bit source and a 3-bit target. Sources: PC, ADDR, RAM, IMM, ALU, I, J, K. Targets: PC, ADDR, RAM, ALU_A, ALU_B, I, J, K. I,J,K are optional general-purpose registers. ALU_A and ALU_B are ALU registers(can only be read as ALU result). IMM is the last decoded immediate value, RAM reads/writes at address provided by ADDR. (It's so simple, I actually can decode/encode/run instructions in my head :P) I would really like any feedback, I have little experience and no formal training :P

@@ALG397 Oh, and I've also got a video where I design and build a simple CPU in LogiSim that is somewhat similar to the MCPU instruction set. It has no audio narration, but I explained what I did in text on the right side. The original recording was about an hour, but the video is speed up 2x(30min), but contains otherwise no editing. It contains some mistakes and debugging, but the basic design is fine and very similar. Technically my architecture can be considered TTA-like(transport-triggered architecture), but it's very much not VLIW, and suports only a single source and target(untypical for TTAs) at a time, and the IMM instruction also doesn't fit the TTA description. MCPU architecture is not my first iteration on a design like this, I've played around with LogiSim and Digital a lot to figure out what architecture features I want/need. I've also played with Minecraft redstone a bit, discovering that basically a stacking height of 2 is always enough, because you can "cross" wires in 2 high, which is somewhat like the WireWorld cellular automata(which has a really cool CPU design for it! My favorite in any CA! Look up WireWorld Computer!), which I also played around with earlier, which lead me to realize that I could build an instruction set that could work on any word width, and that could be created in layers that only need to be connected to the previous/next layer(important for building compactly in Minecraft; This basically means the data path is completely 2D in Minecraft), but also means this is probably easier to implement serially(important for WireWorld) or in other creative ways like shaders etc.
