SSE4a

SSE4a is a set of 4 SIMD instructions introduced in AMD K10 microarchitecture:

  • EXTRQ - extracts a set of bits from a register.
  • INSERTQ - inserts a set of bits located in source register into a destination register.
  • MOVNTSS - writes register's lower 32 bits into memory using non-temporal hint (cache is not updated and data is written directly to memory).
  • MOVNTSD - writes register's lower 64 bits into memory using non-temporal hint (cache is not updated and data is written directly to memory).
