Die analysis of the 8087 math coprocessor's fast bit shifter

tech

Ken Shirriff examines Intel's eighty eighty-seven, the floating-point coprocessor released in nineteen eighty that accelerated mathematical calculations by up to one hundred times and became the foundation for the I E E E seven fifty-four standard. Through microscopic analysis of the silicon die, he shows how the chip's binary shifter—a critical component—performs complex operations in remarkably minimal space.
