𝗧𝗮𝗯𝗹𝗲 𝗼𝗳 𝗰𝗼𝗻𝘁𝗲𝗻𝘁𝘀 00:00 Topic for today 00:24 Introduction to Instruction Set Architecture (ISA) and Why We Care? 02:08 Relation between CPU and ISA 03:50 CISC vs RISC Architecture - Instruction Decoding 06:32 CPU and Registers 07:18 The need for ISA - The abstraction layer 09:12 Back to CISC vs RISC 09:37 Exploring the relation between architecture and instructions 11:40 Assembly instructions and ISA 13:25 Directives in assembly language 14:03 RISC architecture and effect on instruction count and formatting 15:41 What does "Reduced" in RISC really mean? 17:38 Dev presents his understanding 18:26 Venturing into different types of ISA - x86, ARM, RISC-V 19:34 ARM and RISC-V architecture 20:33 ARM as a company and its business model 23:52 Background of RISC-V, Royalty, and crossing the boundary and drifting... 28:44 Back to the story of the Origin of RISC-V 29:51 Ratification and Idea of ISA Extensions 30:31 Integer Extension - The minimum instructions to be implemented to be called RISC-V 31:01 More about the idea of extensions to the ISA 32:05 Intel x86 ISA 35:00 CISC, Memory Speed and the influence on the CPU design 36:36 ISA and effects on the complexity of Compiler 38:00 Example of CISC instruction - Find substring! 38:45 More on compiler design and abstractions - GCC and Clang 41:42 Detour: MIPS, SPARC etc architecture 43:33 The Story of Origin of ARM 45:57 Apple, ARM, and parts of the Origin Story. 48:39 Why Should an embedded engineer care about ISA? 49:27 Should the C/C++ programmer care? 50:24 When assembly shines - What cannot be done in C/C++ 51:10 Implementing locks and the use of atomic instructions 52:30 Implementing scheduler and special instructions 55:17 Standards and abstraction - memory barrier for example 56:54 TECH GLITCH! (skip) 58:30 Back to architecture and effect on compiler design. 01:02:57 Rajat's work at ATMEL and the source code in Assembly 01:03:09 Assembly and Highspeed I/O 01:04:18 Converting C to assembly and optimizing it. 01:05:47 Accidental detour to wifi firmware...
