- In 1979, Intel introduced the 8088 microprocessor, a variant of the 16-bit 8086 processor. IBM’s decision to use the 8088 processor in the IBM PC (1981) was a critical point in computer history, leading to the dominance of the x86 architecture that continues to the present.1 One way that the 8086 and 8088 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 8088 from die photos and this blog post discusses what I’ve uncovered about the prefetch circuitry.

Syria (Arabic: سُورِيَا or سُورِيَة, romanized: Sūriyā), officially the Syrian Arab Republic (Arabic: الجمهورية العربية السورية, romanized: al-Jumhūrīyah al-ʻArabīyah as-Sūrīyah), is a Western Asian country located in the Eastern Mediterranean and the Levant.
