After years of speculation and months of anticipation, Apple launched their first desktop and laptop computers powered by their own chip design - M1 SoC.After years of speculation and months of anticipation, Apple launched their first desktop and laptop computers powered by their own in-house chip design вЂ” M1 SoC. I make a skype-out call, and the call works, but then I I've got a user who is trying to make calls using skype for business on a MacBook but when they do, the mic doesn't seem to be working. All of the audio settings are turned up full on the skype settings and the strange things is that in the system preferences I can see that the mic is picking up sound and working fine.How to turn off System Integrity Protection in macOSWorking at Apple.

What we need to know about is the M1 itself.Keysight World 2021 вЂ“ Everyone and Everything, ConnectedIf there was anything vanilla among the three products Apple announced, it was the Mac Mini. But I doubt there is anything terribly new to see on the system level. With the announcement of the newest Cupertino Chip and the lineup of supported computers, Apple assured us that the M1 would be a new design.Like everyone from Shanghai to Chicago to Shlisselburg in this game, a new product, particularly one from Apple, can mean only one thing вЂ“ TEARDOWN. For a long time, pundits theorized that the design using ARM cores would see Apple more or less moving an A-series design from mobile over to (at least low end) Macs. Buzz is their business.The speculation for many years was what shape this new design would take.

If you like it, great, but thatвЂ™s just not my thing. A lot of вЂњtechвЂќ coverage addresses this, often in nauseating detail. Sorry, but I didnвЂ™t take videos. There was a bigger one, but that comes later.After product purchase, the next phase of teardown is the unboxing. Getting the M1 in the least expensive way possible was one goal.

Cell phones are always more fun вЂ“ heat, sharp tools, glue, fumes, and occasionally pyrotechnics from soft lithium power packs. It was distinctively Apple.Getting the logic board out of a Mac Mini presents little challenge. AppleвЂ™s origamists did a great job with the paper card used to contain the power cord under the unit.

This is the type with the recessed center to accommodate the small pillars in the center of the assembly screws. The вЂњHвЂќ is what tripped me up. The вЂњtamper proofвЂќ driver required to open the box is designated Torx T6H.

With screws removed, logic board slid right out of the case. I guess the drivers themselves are not tamper proof.Back to the M1. Tricky set up aside (thanks Mohamed), a few minutes on the milling machine and voila! A regular T6 driver was quickly converted. вЂњTantalizingly close, isnвЂ™t it?вЂќFortunately, I analyzed the M1 with the support of my good friends at MuAnalysis. I can hear the designers at Apple.

There are two side-by-side LPDDR4 DRAM chips co-located on the BGA substrate next to the M1 processor (DRAM placed end-to-end beside the processor silicon). The two DRAM packages do not benefit from a heat sink.Further to the point about Apple marketing material, several features of the image of the package were accurate. As you may have seen from Apple marketing material, the M1 processor is co-located on a package substrate (ball grid array вЂ“ BGA). Both the processor and PMIC make use of the finned heat sink that is in turn cooled by the internal fan.

Looking at the final assembled packaged would give you the backside view of the silicon. That means that the circuitry side is face down. This is obviously inaccurate for a number of reasons, but this was only mild artistic license.First, the device is flip chip attached to the BGA.

The original internet posts of M1 teardowns were from 16G computers which showed a pair of DRAM packages. Apple made it unique.One more quick note about device arrangement for anyone wondering about the 8G versus 16G RAM versions of the computers. Usually, these heat spreaders cover the entire top package surface.Even in this subtlety, Apple found a way to вЂњthink different.вЂќ This type of system-in-package (SiP) with 2D arrangement of processor and DRAM is uncommon. This thin metal (probably aluminum) covered only the side of the BGA substrate containing the M1 silicon.

No thought was given to the idea of creating two package designs for one computer platform. Other images I have seen on blogs or Twitter were also Hynix devices.Naturally, Apple needed to maintain the symmetry and signal paths for the high-speed RAM chips by using two components regardless of system memory size. My Mac Mini contained Hynix LPDDR4 chips. It is simply a matter of packaging half the die in each package for the 8G models. There are still two for 8G systems, but each package contains half the density of the 16G components.

Keeping the DRAM physically close and shared between CPU and GPU cores allows the SoC design to shed some on-chip SRAM cache and reduce the chip footprint.This is not to say that the proximity is a milestone. It allows all the processing cores вЂ“ both CPU and GPU вЂ“ to share one large pool of memory. UMA is the model of efficiency. Apple highlighted the new вЂњUniversal Memory ArchitectureвЂќ or UMA in the launch (and now on the website).

(For more on thermal design power, consider performance differences between the M1 Macbook Air and the more powerful M1 Macbook Pro which adds a fan for heat extraction.)The M1 package inspection has so far been superficial. The M1 die needs to have a large surface available to contact a heatsink. The non-mobile computing platforms need to have higher performance where the processor is going to generate more heat. Phone and tablet processors are designed to run cooler and allow for the extra thermal resistance of the PoP reducing heat transfer out of the chip. Whether itвЂ™s a Qualcomm Snapdragon processor or one of AppleвЂ™s own A-series chips, an LPDDR4 memory component is stacked over it in a 3D packaging concept known as package-on-package (PoP).It may seem like the M1вЂ™s memory placement takes a step back, but the next-door location (as opposed to the apartment on the next floor in PoP) is required for laptop and desktop computer systems.

A functional block illustration included operational details many of which can be attributed to physical IP within the SoC:Apple did not identify the die locations of any of these blocks even if it was suggested by the graphics used to describe the CPU, GPU, and neural engine. Apple provided more than a few clues. Much of the anticipation of the M1 focused on the SoC itself and what might come out of the design team. Patience will be rewarded.M1 functionality, many but not all represent physical blocks on the SoC (source: Apple)It took a while, but I managed to meander my way back to the new Apple silicon. I expect there are some very enticing features, perhaps downright innovations, hidden under the hood. But AppleвЂ™s mobile processor packaging and board level integration have been pushing boundaries.

Once the logic board was out and the integrated heat spreader was popped off, it was a quick stop for some backside photos. (Source: Apple, MuAnalysis)This was verified with the assistance of MuAnalysis in Ottawa, Canada. Click the image to enlarge. But it turned out to be a precise version of the SoC physical design. As discussed above, this was an inexact representation in the sense that it was not true to the assembly onto the package substrate. However, Apple did show something that looked very much like a genuine optical image of the SoC die layout on their graphic of the physical product.

This approach netted a detailed die image in a little over a half hour.Now, the real analysis begins. Teardown вЂ“ 20 minutes (not including tool manufacturing)The TTRI (time to real information) is a lot faster than you might expect. A quick flip of that mirror image showed it was a dead ringer (although not color obviously) for the version released by Apple marketing. Silicon is transparent to IR which makes flip chip technology a treat for people in my business.
