Description
Converts the signed integer in register rA to floating-point and puts the result in register rD. This is a
32-bit rounding signed conversion that will produce a 32-bit floating-point result.
Pseudocode
(rD) ← float ((rA))
Registers Altered
•rD
Latency
• 4 cycles with C_AREA_OPTIMIZED=0
• 6 cycles with
C_AREA_OPTIMIZED=1
• 1 cycle with
C_AREA_OPTIMIZED=2
Note
This instruction is only available when the MicroBlaze parameter C_USE_FPU is set to 2 (Extended).
