Jr is followed by a register name rather than a label. S 2 → mips(s 1) mips(s 2). This gives 26 bits to say where we are jumping to.

Lo ← r [$rs] 24: As @jester pointed out, routines (functions in c jargon) must be careful to preserve their return address present in $ra. Managing resources is an important part of function calls. Jr is followed by a register name rather than a label.

On the hydra and tesla machines, each register is at least 64 bits, so our hydra and tesla labs machines are 64 bits. Online it says this boundary is 256mb but 2^28 bits is 32mb and not 256mb. —to keep important data from being overwritten, registers are saved This gives 26 bits to say where we are jumping to. Here.

The difference is that the target address for jr comes from a register specified in the instruction. The classification below refines the classification according to coding format, taking into account the way that the various instruction fields are used in the instruction. Today we focused on implementing function calls in mips. Undefined if $rs = $rd: Mips has several registers.

J is stored in memory, i.e. Unless the routine is a leaf routine (one that doesn't do any call) $ra must be saved somewhere anyway. Online it says this boundary is 256mb but 2^28 bits is 32mb and not 256mb. To divide by 4, you shift right by 2 bits because shifting right n bits divides a number by (2^n)..

The address stored in a j instruction is 26 bits of the address associated with the specified label. M{i}is a value (contents) of the byte at the memory address i i. This gives 26 bits to say where we are jumping to. On the hydra and tesla machines, each register is at least 64 bits, so our hydra and tesla.
