a) Set on less than instruction:
```
slt $t0, $s1, $s2 # If $s1 is less than $s2, set $t0 to 1, otherwise set $t0 to 0
```
b) Set on less than immediate instruction:
```
slti $t0, $s1, 10 # If $s1 is less than 10, set $t0 to 1, otherwise set $t0 to 0
```
c) Branch equal instruction:
```
beq $s1, $s2, label # If $s1 is equal to $s2, branch to label
```
d) Branch if not equal instruction:
```
bne $s1, $s2, label # If $s1 is not equal to $s2, branch to label
```
Note: In all the above examples, `$s1` and `$s2` are registers and `label` is a label in the program.

Write the assembly language program using the following instruction a) Set on less than instruction b) Set on less than immediate instruction c) Branch equal
a) Set on less than instruction:
```
slt $t0, $s1, $s2 # if $s1 < $s2, $t0 = 1, otherwise $t0 = 0
```
This instruction sets the value of register $t0 to 1 if the value in register $s1 is less than the value in register $s2, otherwise it sets $t0 to 0.
b) Set on less than immediate instruction:
```
slti $t0, $s1, 10 # if $s1 < 10, $t0 = 1, otherwise $t0 = 0
```
This instruction sets the value of register $t0 to 1 if the value in register $s1 is less than the immediate value 10, otherwise it sets $t0 to 0.
c) Branch equal instruction:
```
beq $s1, $s2, label # if $s1 == $s2, jump to the instruction at label
```
This instruction checks if the value in register $s1 is equal to the value in register $s2. If they are equal, the program jumps to the instruction at the label, otherwise it continues to the next instruction.
show me detail performance data for 64bit multiply instruction, and 32bit multiply instruction on cortex-M0 thumb instruction set.
I'm sorry, but as an AI language model, I don't have access to specific performance data for the Cortex-M0 Thumb instruction set. However, I can provide some general information about the performance of 64-bit and 32-bit multiply instructions on this architecture.
The Cortex-M0 is a 32-bit microcontroller designed for low-power and cost-sensitive applications. It uses the Thumb instruction set, which is a compressed version of the ARM instruction set.
The Cortex-M0 supports two types of multiply instructions: 32-bit multiply (MUL) and 32-bit multiply-accumulate (MULADD). The MUL instruction performs a 32-bit by 32-bit multiplication and produces a 32-bit result. The MULADD instruction performs a 32-bit by 32-bit multiplication and adds the result to a 32-bit accumulator, producing a 32-bit result.
The Cortex-M0 does not have a dedicated 64-bit multiply instruction. However, it can perform a 64-bit multiplication using multiple 32-bit multiply instructions and addition operations. This approach is slower than a dedicated 64-bit multiplication instruction.
In general, the performance of the multiply instructions on the Cortex-M0 depends on several factors, such as the clock frequency, the memory speed, and the data size. The performance can also be affected by the specific implementation of the microcontroller.
