Understanding the x87 FPU Data Register Stack

A brief introduction to the x87 FPU data registers - The CPU implements these registers as a stack. The operation of the fpu stack is discussed through a simple example that loads two double values on the stack and multiplies them using the fmul instruction. Using the concepts in this video we will write inline assembly code to compute the area of a circle. More details: Chapter 8 (Programming with the x87 FPU) : Vol 1 Intel Software Developers manual.
