Maybe I missed something, but does ARM have a "zero" register like MIPS that always returns 0 bits?
@joetheprofessor6260

No, the ARM 7M architecture does not have a zero register.

@@joetheprofessor6260 thanks, its making more sense aa I get further down the video list. I guess with 32 GPRs on MIPS 32 they could afford to "waste" one for the zero register for some neat tricks. I know MIPS from many years back, but I am learning ARM because it seems to have basically replaced it everywhere.

@@joetheprofessor6260 just got caught up with more recent ARMv8/aarch64 and it seems like they took a page out of MIPS' book. So there are now 32 GPR and register #0 functions as a constant 0 filled.

What is a Gibi byte?
@joetheprofessor6260
@joetheprofessor6260 5 жыл бұрын
A gibibyte is 2^30 bytes. On the other hand, a gigabyte is 10^9 bytes. The name comes from "GIga BInary". Similarly, a mebibyte is 2^20 byte while a megabyte is 10^6 bytes. These are internationally standardized definitions; I didn't make them up.

7:45 isnt processor access 4 byte alignment of memory?
@joetheprofessor6260
@joetheprofessor6260 5 жыл бұрын
From an architectural point of view, there is no general requirement for 4-byte alignment. Instruction fetches must be half-word aligned. Data load/stores can use byte addresses, such as LDRB and STRB.

Stop saying "gibibyte". It's GIGABYTE and you know it. Stop trying to sound special.
@joetheprofessor6260
@joetheprofessor6260 7 жыл бұрын
Sorry, but international standards and style guides for professional engineering publishing say that 2^30 is a gibibyte. The heart of engineering communication is clarity, and it is very important that we distinguish between 10^9 (giga) and 2^30 (gibi). See, for example, IEEE-Std-1541...I'm not just making this up.

JEDEC sais gigabyte, while IEC says gibibyte. The important thing is that they are both talking about 1024*1024*1024 bytes.

A gigabyte is a 1000 megabytes just as a gigawatt is 1000 megawatts. Unless you think that a gigawatt is 1024 megawatts, in which case you are stupid.
