- Unusual circuits in the Intel 386’s standard cell logic (righto.com)
I’ve been studying the standard cell circuitry in the Intel 386 processor recently. The 386, introduced in 1985, was Intel’s most complex processor at the time, containing 285,000 transistors. Intel’s existing design techniques couldn’t handle this complexity and the chip began to fall behind schedule. To meet the schedule, the 386 team started using a technique called standard cell logic. Instead of laying out each transistor manually, the layout process was performed by a computer.
- Then as to the Analysis of the ancients and the Algebra of the moderns, besides that they embrace only matters highly abstract, and, to appearance, of no use, the former is so exclusively restricted to the consideration of figures, that it can exercise the Understanding only on condition of greatly fatiguing the Imagination;[^1] and, in the latter, there is so complete a subjection to certain rules and formulas, that there results an art full of confusion and obscurity calculated to embarrass, instead of a science fitted to cultivate the mind.
