What does the VPBROADCASTB instruction do?

Output

# VPBROADCASTB Instruction VPBROADCASTB is an x86 SIMD instruction that broadcasts (replicates) a single byte value to all elements of a vector register. ## Operation - Takes a single byte from the source operand - Copies this byte value to every byte position in the destination vector register ## Syntax

VPBROADCASTB xmm1, xmm2/m8    ; AVX2 - 128-bit destination
VPBROADCASTB ymm1, xmm2/m8    ; AVX2 - 256-bit destination
VPBROADCASTB zmm1, xmm2/m8    ; AVX-512 - 512-bit destination
## Example If the source byte contains the value 0x42: - With XMM (128-bit) destination: fills all 16 bytes with 0x42 - With YMM (256-bit) destination: fills all 32 bytes with 0x42 - With ZMM (512-bit) destination: fills all 64 bytes with 0x42 ## Usage This instruction is particularly useful in SIMD programming when you need to compare multiple data elements against the same value or perform the same operation with a constant across an entire vector.

Below is a student's answer to a question about what a particular instruction does: # VPBROADCASTB Instruction VPBROADCASTB is an x86 SIMD instruction that broadcasts (replicates) a single byte value to all elements of a vector register. ## Operation - Takes a single byte from the source operand - Copies this byte value to every byte position in the destination vector register ## Syntax

VPBROADCASTB xmm1, xmm2/m8    ; AVX2 - 128-bit destination
VPBROADCASTB ymm1, xmm2/m8    ; AVX2 - 256-bit destination
VPBROADCASTB zmm1, xmm2/m8    ; AVX-512 - 512-bit destination
## Example If the source byte contains the value 0x42: - With XMM (128-bit) destination: fills all 16 bytes with 0x42 - With YMM (256-bit) destination: fills all 32 bytes with 0x42 - With ZMM (512-bit) destination: fills all 64 bytes with 0x42 ## Usage This instruction is particularly useful in SIMD programming when you need to compare multiple data elements against the same value or perform the same operation with a constant across an entire vector. Does the student's say something similar to "Load integer data from the source operand (the second operand) and broadcast to all elements of the destination operand (the first operand)."? If the answer is correct say "The student passes" otherwise "The student fails".

Output

The student's explanation does convey the idea that the instruction takes a single byte from the source operand and broadcasts it to all elements of the destination vector register. This aligns with the concept of loading integer data from the source operand and broadcasting it to all elements of the destination operand. Therefore, the student's answer is consistent with the statement provided. The student passes.

# VPBROADCASTB Instruction The VPBROADCASTB instruction is an AVX (Advanced Vector Extensions) instruction that broadcasts a single byte value to all elements of a destination vector register. ## Functionality - Takes a single byte (8 bits) from the source operand - Replicates (broadcasts) that byte to all byte positions in the destination vector register ## Syntax

VPBROADCASTB xmm1, xmm2/m8    ; 128-bit destination
VPBROADCASTB ymm1, xmm2/m8    ; 256-bit destination 
VPBROADCASTB zmm1, xmm2/m8    ; 512-bit destination (AVX-512)
## Example If the source byte is `0x5A`: - In a 128-bit XMM register: All 16 bytes become `0x5A` - In a 256-bit YMM register: All 32 bytes become `0x5A` - In a 512-bit ZMM register: All 64 bytes become `0x5A` ## Use Cases This instruction is particularly useful in SIMD programming when you need to: - Compare vectors against a constant value - Initialize vectors with the same value in each element - Perform operations requiring the same value across multiple data elements The instruction was introduced with AVX2 and extended with AVX-512.

The student's explanation does convey the idea that the VPBROADCASTB instruction takes a single byte from the source operand and broadcasts it to all elements of the destination vector register. This is similar to saying "Load integer data from the source operand (the second operand) and broadcast to all elements of the destination operand (the first operand)." Therefore, the student's answer aligns with the intended functionality of the instruction. The student passes.
