Rounding injection scheme for floating-point to integer conversion

摘要

According to one general aspect, an apparatus may include a memory, a normalization engine, a lookup table, and an adder. The memory may be configured to store a floating-point number formatted in a floating-point format. The normalization engine may be configured to normalize at least a portion of the floating-point number to create a normalized number. The lookup table may be configured to generate an injection constant based upon a predefined set of rounding values specifically for converting a floating-point number to an integer number. The adder may be configured to create an integer result by adding the normalized number and the injection constant.

1. An apparatus comprising:
a memory configured to store a floating point number formatted in a floating point format; a normalization engine configured to normalize at least a portion of the floating point number to create a normalized number; a lookup table configured to generate an injection constant based upon a rounding mode for converting a floating-point number to an integer number; and an adder configured to create an integer result by adding the normalized number and the injection constant.
