- Intel released the powerful Pentium processor in 1993, establishing a long-running brand of processors. Earlier, I wrote about the ROM in the Pentium’s floating point unit that holds constants such as π. In this post, I’ll look at some interesting circuits associated with this ROM. In particular, the circuitry is implemented in BiCMOS, a process that combines bipolar transistors with standard CMOS logic.
- My collection of Intel 8080 microprocessors (demin.ws)
I started programming twenty year ago coding in machine codes for Intel 8080. This microprocessor was my lucky pass to the fascinating world of bits and bytes. Years later developing various emulators of i8080 and tackling with undocumented and partially documented features of this processor I decided to collect real chips from different manufacturers and examine them using the 8080 CPU Exerciser.
