- The Methow Unit is located in the foothills on the east side of the Methow Valley. A narrow strip of land about 18 miles long, it varies in width from 0.5 mile to 2 miles, stretching from Falls Creek on the north end to Frazer Creek and Highway 20 on the south end. Habitats vary from Ponderosa pine and Douglas-fir forests, to shrubsteppe, to aspen/cottonwood riparian areas along stream courses. This unit was purchased primarily for mule deer winter range, but it hosts a variety of wildlife, including nesting golden eagles.
- How the 8086 processor’s microcode engine works (righto.com)
The 8086 microprocessor was a groundbreaking processor introduced by Intel in 1978. It led to the x86 architecture that still dominates desktop and server computing. The 8086 chip uses microcode internally to implement its instruction set. I’ve been reverse-engineering the 8086 from die photos and this blog post discusses how the chip’s microcode engine operated. I’m not going to discuss the contents of the microcode1 or how the microcode controls the rest of the processor here. Instead, I’ll look at how the 8086 decides what microcode to run, steps through the microcode, handles jumps and calls inside the microcode, and physically stores the microcode. It was a challenge to fit the microcode onto the chip with 1978 technology, so Intel used many optimization techniques to reduce the size of the microcode.
