Chapter 8 Instruction Set
Chapter 8 Instruction Set 80 80 This chapter lists the PowerPC instruction set in alphabetical order by mnemonic. Note that each entry includes the instruction formats and a quick reference ‘legend’ that provides such information as the level(s) of the PowerPC architecture in which the instruction may be found—user instruction set architecture (UISA), virtual environment architecture U (VEA), and operating environment architecture (OEA); and the privilege level of the V instruction—user- or supervisor-level (an instruction is assumed to be user-level unless the O legend specifies that it is supervisor-level); and the instruction formats. The format diagrams show, horizontally, all valid combinations of instruction fields; for a graphical representation of these instruction formats, see Appendix A, “PowerPC Instruction Set Listings.” The legend also indicates if the instruction is 64-bit, , 64-bit bridge, and/or optional. A description of the instruction fields and pseudocode conventions are also provided. For more information on the PowerPC instruction set, refer to Chapter 4, “Addressing Modes and Instruction Set Summary.” Note that the architecture specification refers to user-level and supervisor-level as problem state and privileged state, respectively. 8.1 Instruction Formats Instructions are four bytes long and word-aligned, so when instruction addresses are U presented to the processor (as in branch instructions) the two low-order bits are ignored. Similarly, whenever the processor develops an instruction address, its two low-order bits are zero. Bits 0–5 always specify the primary opcode. Many instructions also have an extended opcode. The remaining bits of the instruction contain one or more fields for the different instruction formats. -

What Do We Mean by Architecture?
Embedded programming: Comparing the performance and development workflows for architectures Embedded programming week FABLAB BRIGHTON 2018 What do we mean by architecture? The architecture of microprocessors and microcontrollers are classified based on the way memory is allocated (memory architecture). There are two main ways of doing this: Von Neumann architecture (also known as Princeton) Von Neumann uses a single unified cache (i.e. the same memory) for both the code (instructions) and the data itself, Under pure von Neumann architecture the CPU can be either reading an instruction or reading/writing data from/to the memory. Both cannot occur at the same time since the instructions and data use the same bus system. Harvard architecture Harvard architecture uses different memory allocations for the code (instructions) and the data, allowing it to be able to read instructions and perform data memory access simultaneously. The best performance is achieved when both instructions and data are supplied by their own caches, with no need to access external memory at all. How does this relate to microcontrollers/microprocessors? We found this page to be a good introduction to the topic of microcontrollers and microprocessors, the architectures they use and the difference between some of the common types. First though, it’s worth looking at the difference between a microprocessor and a microcontroller. Microprocessors (e.g. ARM) generally consist of just the Central Processing Unit (CPU), which performs all the instructions in a computer program, including arithmetic, logic, control and input/output operations. Microcontrollers (e.g. AVR, PIC or 8051) contain one or more CPUs with RAM, ROM and programmable input/output peripherals. -

A Developer's Guide to the POWER Architecture
http://www.ibm.com/developerworks/linux/library/l-powarch/ 7/26/2011 10:53 AM English Sign in (or register) Technical topics Evaluation software Community Events A developer's guide to the POWER architecture POWER programming by the book Brett Olsson , Processor architect, IBM Anthony Marsala , Software engineer, IBM Summary: POWER® processors are found in everything from supercomputers to game consoles and from servers to cell phones -- and they all share a common architecture. This introduction to the PowerPC application-level programming model will give you an overview of the instruction set, important registers, and other details necessary for developing reliable, high performing POWER applications and maintaining code compatibility among processors. Date: 30 Mar 2004 Level: Intermediate Also available in: Japanese Activity: 22383 views Comments: The POWER architecture and the application-level programming model are common across all branches of the POWER architecture family tree. For detailed information, see the product user's manuals available in the IBM® POWER Web site technical library (see Resources for a link). The POWER architecture is a Reduced Instruction Set Computer (RISC) architecture, with over two hundred defined instructions. POWER is RISC in that most instructions execute in a single cycle and typically perform a single operation (such as loading storage to a register, or storing a register to memory). The POWER architecture is broken up into three levels, or "books." By segmenting the architecture in this way, code compatibility can be maintained across implementations while leaving room for implementations to choose levels of complexity for price/performances trade-offs. The levels are: Book I. -
