Apples M1 Processor: The hardware behind the hype

Apples just announced M1 processor makes a lot of bold claims about performance is a big departure from the CISC based Intel x86 platform. This video explores how concepts from computer organization and architecture can be applied to information available to make educated assumptions about initial performance and future prospects of the platform. We look in-depth at what we know about the hardware used in this platform and see if it merits the hype.

This video assumes you have a basic computer science background and understanding of CISC vs RISC architectures, System on a Chip (SoC), CPU pipelining / multiple execution units, instruction cycles and memory caching. It is produced for my undergraduate course: Computer Organization and Architecture, as a way to tie all of these concepts back to Apple's announcement.

We will discuss some of the meaningful data we were able to tease out of the marketing driven announcement and look at what we know from Apples existing mobile "M" series of processors. Some of the concepts we will discuss are Unified Memory Architecture and Ultra-wide Execution Architecture. We will also look at Apple's released information on cache memory and what they have done in this area in the recent past in the mobile space for guidance and predictions.

If you have not seen the Little Man Computer (LMC) series of videos, they explore how a computer works at it most fundamental level. You can find them here:

* A "Hello LMC" video where we do a smaller program and talk more in-depth about the instruction cycle and basic instructions: https://youtu.be/QneVgKf2eVg
* And an intermediate step where we introduce branching and explore recreating conditional statements with LMC: https://youtu.be/fXMCnzdNemc
* Finally we explore iteration, labels and advanced LMC: https://youtu.be/hFg1etP_sFM
