assembly - How are ARM Registers referred to in binary -

I know that there are a lot of registers in the ARM and I was thinking that the mapping register (r0 - r15, cpsr, etc. ) For their binary representation to be used in the final binary (Basically, the values ​​that go to RN and RD areas in the instruction) For example, this is r0 0b0000 and r1 bus 0b0001 ? If so, what is it when it comes to specific CPU mode or does the CPU mode do not affect the register's identifier (I think it should be a separate code).

Thank you.

Obtain the ARM architecture reference manual from infocenter.arm.com. Everything you want to know is right.

Encoder on r15 = 4'b1111 for instructions r0 = 4'b0000 and r1 4'b0001, etc. Some registers were banked based on mode, supervisor mode, user mode interrupt mode, etc. The instruction is not able to change the encoding R13, 13 in the encoding, but somewhere in the processor, if there is some taste in the real register, it is not visible to us in order to get it His argument is buried.

The instructions of thumb are generally limited to R-R7 for most instructions, some are used specifically to go for more number of registers, R8-R15 , But the encoding is the same r0 = 0 r1 = 1, r2 = 2 and so on. r0, r0, r1 add r0, r0, r2 add r0, r0, r3 add r0,

R0, r4 ... r0, r1, r0 add r0, r2, r0 add r0, r3, r0 ...

and see what bits change after it is connected again Go ...
