- 2001: A Space Odyssey is a 1968 epic science fiction film produced and directed by Stanley Kubrick. The screenplay was written by Kubrick and Arthur C. Clarke, and it was inspired by multiple short stories by Clarke, including “The Sentinel” (1951). Clarke also published a novelisation of the film, in part written concurrently with the screenplay, after the film’s release. 2001: A Space Odyssey stars Keir Dullea, Gary Lockwood, William Sylvester, and Douglas Rain and follows a voyage by astronauts, scientists, and the sentient supercomputer HAL 9000 to Jupiter to investigate an alien monolith.
- Inside the Intel 386 processor die: the clock circuit (righto.com)
Processors are driven by a clock, which controls the timing of each step inside the chip. In this blog post, I’ll examine the clock-generation circuitry inside the Intel 386 processor. Earlier processors such as the 8086 (1978) were simpler, using two clock phases internally. The Intel 386 processor (1985) was a pivotal development for Intel as it moved x86 to CMOS (as well as being the first 32-bit x86 processor). The 386’s CMOS circuitry required four clock signals. An external crystal oscillator provided the 386 with a single clock signal and the 386’s internal circuitry generated four carefully-timed internal clock signals from the external clock.
