VEX V5 is a STEM learning system designed by VEX Robotics and the REC Foundation to help middle and high school students develop problem-solving and computational thinking skills. [9] It was introduced at the VEX Robotics World Championship in April 2019 as a replacement for a previous system called VEX EDR (VEX Cortex).
The REX prefix provides additional space for encoding 64-bit addressing modes and additional registers present in the x86-64 architecture. Bit-field W changes the operand size to 64 bits, R expands reg to 4 bits, B expands r/m (or opreg in the few opcodes that encode the register in the 3 lowest opcode bits, such as "POP reg"), and X and B expand index and base in the SIB byte.
While VEX Robotics, inc. and the REC Foundation closely collaborate on the VEX Robotics competition, they are separate organizations with their own executive and company structures. The REC Foundation also hosts competitions and programs beyond VEX Robotics, such as the Aerial Drone Competition and the International Robotics Honor Society. [5]
FIRST Tech Challenge (FTC), formerly known as FIRST Vex Challenge, is a robotics competition for students in grades 7–12 to compete head to head, by designing, building, and programming a robot to compete in an alliance format against other teams.

The ModR/M byte specifies one operand (always a register) with reg field, and the second operand is encoded with mod and r/m fields, specifying either a register or a location in memory. Base-plus-index and scale-plus-index addressing require the SIB byte, which encodes 2-bit scale factor as well as 3-bit index and 3-bit base registers.

VEX coding is also used for instructions operating on the k0-k7 mask registers that were introduced with AVX-512. The alignment requirement of SIMD memory operands is relaxed. [5] Unlike their non-VEX coded counterparts, most VEX coded vector instructions no longer require their memory operands to be aligned to the vector size.
