SIMD vectorize atan2 using ARM NEON assembly
SIMD vectorize atan2 using ARM NEON assembly
should help you out See math-neon for an existing single valued float implementation. As it has no (or little) conditionals, it should translate well to an SIMD implementation.As the ARM NEON doesn't have an instruction to calculate this directly, th

Inline Assembly Procedure Crash When Accessing Arguments
Inline Assembly Procedure Crash When Accessing Arguments
wish help you to fix your issue As it turns out SEGMENT was defaulting to USE16 instead of USE32/FLAT, which was causing it to be assembled in 16-bit mode, despite little explanation in the documentation.Also as Michael said, the assembly file can be

How do assembly instruction differentiate between register, memory address, immediate value or offset parameter?
How do assembly instruction differentiate between register, memory address, immediate value or offset parameter?
wish help you to fix your issue The instructions are encoded in the hardware. How this is exaclty done is CPU specific. On the x86 architecture, you have some bits which define what the operand adressing modes are. For more detail you should refer to

the why of MOV command restrictions
the why of MOV command restrictions
this one helps. x86 MOV instructions simply do not support both a load and a store in the same instruction. You can either load from memory to a register, or store a register to memory. If you want to copy memory to memory in one instruction you need

Why a Word is 2 bytes and not 4 bytes in x86 Assembly?
Why a Word is 2 bytes and not 4 bytes in x86 Assembly?
Any of those help For historical reasons. The x86 family started as a 16-bit architecture (8086). That was the time when the instruction set was defined, and all further processors have to be backward-compatible.The 80386 was the first 32-bit process

Assembly memory operands clarification
Assembly memory operands clarification
should help you out I understand when for example [BX] is in between brackets it is referring to its memory contents. But at the same time I do not understand that.

Syntax error in assembly when using letter "C"
Syntax error in assembly when using letter "C"
should help you out The name C happens to be one of the language type names used by some of MASM's directives, e.g. .MODEL and PUBLIC - that's why you can't use it as a name for your own symbols. You'll just have to pick another name.

Filling up Delayed Branch slots
Filling up Delayed Branch slots
seems to work fine For (A), J X is an unconditional jump to a single fixed label (presumably within the range provided by the ISA), so it does not have any data dependencies on previous instructions. Since the ADD has a name dependence on the result

Can I read label value in assembly?
To fix the issue you can do What you show will work in e.g. nasm, but the result may not be what you expect.A little more information into what you're writing would help this answer be more specific. (Typical user-mode ELF application? Stand-alone bi

Passing a 1 byte argument to a function?
Passing a 1 byte argument to a function?
To fix this issue The stack must be aligned. If you make 16 bit real mode program, the stack must be aligned on 16 bits. If you make 32 bit, protected mode program the stack must be aligned on 32 bits. But you don't need to pass exactly 1 byte to the

Bootloader - Loading assembly kernel, problems with memory addresses and copying data
Hope that helps int 13/02 expects es:bx as input, but you only set up es, bx is uninitialized. You should set it to point where you want to load your data, careful not to overwrite your own boot sector. As such, mov bx, 512 sounds like a good idea.An
