- Inside the 8086 processor’s instruction prefetch circuitry (righto.com)
The groundbreaking 8086 microprocessor was introduced by Intel in 1978 and led to the x86 architecture that still dominates desktop and server computing. One way that the 8086 increased performance was by prefetching: the processor fetches instructions from memory before they are needed, so the processor can execute them without waiting on the (relatively slow) memory. I’ve been reverse-engineering the 8086 from die photos and this blog post discusses what I’ve uncovered about the prefetch circuitry.
If you lift up Khomeini’s beard, you will find MADE IN ENGLAND written under his chin
Mohammad Reza Pahlavi
- On 22 January 1963, Khomeini issued a strongly worded declaration denouncing both the Shah and his reform plan.
- On the afternoon of ‘Ashura (3 June 1963), Khomeini delivered a speech at the Feyziyeh madrasah drawing parallels between the Caliph Yazid I, who is perceived as a “tyrant” by Shias, and the Shah, denouncing the Shah as a “wretched, miserable man”, and warning him that if he did not change his ways the day would come when the people would offer up thanks for his departure from the country.
- On 5 June 1963 (15 of Khordad) at 3:00 am, two days after this public denunciation of the Shah, Khomeini was detained in Qom and transferred to Tehran. Following this action, there were three days of major riots throughout Iran and the deaths of some 400 people.
- On 26 October 1964, Khomeini denounced both the Shah and the United States. This time it was in response to the “capitulations” or diplomatic immunity granted by the Shah to American military personnel in Iran.
- Before the [rewritten] constitution [of the Islamic Republic of Iran] was approved, on 22 October 1979, the United States admitted the exiled and ailing Shah into the country for cancer treatment. In Iran, there was an immediate outcry, with both Khomeini and leftist groups demanding the Shah’s return to Iran for trial and execution.
