Cortex Authority Manual - Floating Point Operations

Floating Point Representation The representation of floating-point numbers follows the IEEE 754 standard, including single precision, double precision, and half precision floating-point numbers. Each floating-point number has a sign bit, an exponent, and a fraction part. Single Precision Floating Point (32 bits) Bit 31: Sign bit (0 indicates positive, 1 indicates negative). Bits 30-23: Exponent … Read more

Using Floating Point and Long Division with TLSR8 Chips from TaiLing Micro

1 Introduction The TLSR8 series (including B85, B87, B80) from TaiLing does not support hardware floating point operations. In practical applications, we often encounter customer feedback requesting the use of floating point and 64-bit data for multiplication and division operations. A software floating point library can be added to achieve this. After consulting with the … Read more
