Line 9: Through extensive microprogramming, [[microarchitecture]]s of smaller scale and simplicity can [[Emulator\|emulate]] more robust architectures with wider [[Word (computer architecture)\|word]] lengths, additional [[execution unit]]s, and so forth. This approach provides a relatively straightforward method of ensuring software compatibility between different products within a processor family. Some hardware vendors, notably [[IBM]]/ and [[Lenovo]], use the term ''microcode'' interchangeably with ''[[firmware]]''. In this context, all code within a device is termed microcode, whether it is microcode or machine code. For instance, updates to a [[hard disk drive]]'s microcode often encompass updates to both its microcode and firmware.<ref>{{cite web \|title=IBM pSeries Servers - Microcode Update for Ultrastar 73LZX (US73) 18/36 GB \|url=http://download.boulder.ibm.com/ibmdl/pub/software/server/firmware/73lzx.html \|url-status=dead \|archive-url=https://web.archive.org/web/20190419105117/http://download.boulder.ibm.com/ibmdl/pub/software/server/firmware/73lzx.html \|archive-date=April 19, 2019 \|access-date=January 22, 2015 \|website=IBM}}</ref> ==Overview==
