Microcode vs Firmware

[muoibangchu]

This ran through my mind while writing a doc, may be dumb one.



I have seen people using the terms Microcode and Firmware in IBM system p world interchangeably.



Firmware update or microcode update



Is that right? Are they synonyms?

More Information:

1. I've even re-cut the firmware from my windows driver, but to no avail
2. Really, it's simpler just to put the microcode in a separate mtd partition and let our kernel code load it automatically
3. Codeness develops firmware and microcode for a variety of platforms including ARM MIPS ADI TI mobile phone systems GSM GPRS Edge bootstrapping firmware
4. Simple Boot Flag at 0x7a set to 0x1 > cpu0(2) debug files 120 > cpu1(2) debug files 120 > platform microcode: firmware: requesting intel-ucode/06-17-0a >
5. The patch is microcode (firmware for a CPU, so to speak) to help work around or fix some of the bugs that the Core 2 Duo has

Yes, they are synonyms. IBM uses the term "microcode" for all sorts of what is commonly known as firmware, for reasons unknown. It is similar to Sun using the term "disk slices" for what is commonly called partitions, etc..



I hope this helps.

1. 1, there is seen the overall operating environment in which the present system for enhanced downloading of firmware (microcode) is accomplished in a rapid and efficient manner
2. It reports the microcode firmware version on most of the different IBM SCSI controllers used on microchannel (MCA) PS/2s (This page does not cover

4. The BIOS can load the microcode or the OS can
5. looks like the microcode driver got switched to use request_firmware recently

As I understand it IBM use:

Firmware for the system embedded code - system firmware.

Microcode for the adapter and device embedded code - adapter microcode.

But all us normal people use either for either, typically firmware is used more often for both.

More Information:

1. data! microcode: CPU3: patch_level=0x1000086 platform microcode: firmware: requesting amd-ucode/microcode_amd
2. Shouldn't microcode-ctl be installed without any firmware at all, and microcide-data point to the intel website?
3. only that firmware/microcode, upload the firmware/microcode to each individual system, and prepare the system for the firmware/microcode update
4. Dec 2 16:53:47 mail kernel: platform microcode: firmware: requesting intel-ucode/06-1a-05
5. Dec 2 16:53:47 mail kernel: microcode: CPU1 sig=0x106a5, pf=0x2, revision=0xf
6. One of the most difficult administration tasks in an AIX environment is attempting to keep the firmware and microcode up-to-date

Um, yes and no :-) Firmware is a piece of software for different kind of peripherals (routers, switches, ...). Microcode goes into the CPU, providing a slightly higher level or more complex commands based on the CPU's basic ("hard-wired") commands. For example, Digital's (R.I.P) VAX (R.I.P) used to have a microcode command to solve a polynomial.
