- In geometry, an isosceles triangle (/aɪˈsɒsəliːz/) is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case. Examples of isosceles triangles include the isosceles right triangle, the golden triangle, and the faces of bipyramids and certain Catalan solids.
- Silicon reverse engineering: The 8085’s undocumented flags (righto.com)
The 8085 microprocessor has two undocumented status flags: V and K. These flags can be reverse-engineered by looking at the silicon of the chip, and their function turns out to be different from previous explanations. In addition, the implementation of these flags shows that they were deliberately implemented, which raises the question of why they were not documented or supported by Intel. Finally, examining how these flag circuits were implemented in silicon provides an interesting look at how microprocessors are physically implemented.
