AMD anuncia que abandona el juego de instrucciones K6-2 que mejoraban el calculo en punto flotante de los procesadores x86.
Básicamente eran estas instrucciones máquina:
- PI2FD – Packed 32-bit integer to floating-point conversion
- PF2ID – Packed floating-point to 32-bit integer conversion
- PFCMPGE – Packed floating-point comparison, greater or equal
- PFCMPGT – Packed floating-point comparison, greater
- PFCMPEQ – Packed floating-point comparison, equal
- PFACC – Packed floating-point accumulate
- PFADD – Packed floating-point addition
- PFSUB – Packed floating-point subtraction
- PFSUBR – Packed floating-point reverse subtraction
- PFMIN – Packed floating-point minimum
- PFMAX – Packed floating-point maximum
- PFMUL – Packed floating-point multiplication
- PFRCP – Packed floating-point reciprocal approximation
- PFRSQRT – Packed floating-point reciprocal square root approximation
- PFRCPIT1 – Packed floating-point reciprocal, first iteration step
- PFRSQIT1 – Packed floating-point reciprocal square root, first iteration step
- PFRCPIT2 – Packed floating-point reciprocal/reciprocal square root, second iteration step
Qué descansen en paz.
