ieee754-practice

A tool designed for people who wish to practice manual conversion of IEEE-754 floating point numbers and bit band aliasing.

Integer Conversions

Shows integer numbers converted from and to any of

• base 2
• base 10
• base 16.

Float Conversions

file '29-1.m4a' Can be used to practice manual conversion to and from IEEE-754 single precision floats

Offers step-by-step conversions of Decimal Numbers to binary and hexadecimal formats according to the IEEE-754 standard. Also enables conversions of Hexadecimal Coded floats to decimal numbers.

Bit Banding

Can be used to practice finding byte addresses from bit-band alias addresses.

The Cortex-M4 is taken as an example, i.e. there are two bit banding areas

• 0x2000 0000 - 0x200F FFFF -> 0x2200 0000 - 0x23FF FFFF for data
• 0x4000 0000 - 0x400F FFFF -> 0x4200 0000 - 0x42FF FFFF for peripherals
