A second, more successful attempt to subset the AVR instruction set is the "AVR tiny" core. The most significant change is that the AVRtiny core omits registers R0–R15. The registers are also not memory-mapped, with I/O ports from 0–63 and general-purpose RAM beginning at address 64.

User manuals and user guides for most non-trivial PC and browser software applications are book-like documents with contents similar to the above list. They may be distributed either in print or electronically. Some documents have a more fluid structure with many internal links. The Google Earth User Guide [4] is an example of this format.
Nevertheless for the most common targets the LLVM MC (machine code) project provides an assembler both as an integrated component of the compilers and as an external tool. Some other self-hosted native-targeted language implementations (like Go , Free Pascal , SBCL ) have their own assemblers with multiple targets.
The PIC18 has a 12-bit RAM address space, divided into 16 pages of 256 bytes. The 8-bit f field determines the address in combination with the a bit and the 4-bit bank select register ( BSR ). If a =0, the BSR is ignored and the f field is sign-extended to the range 0x000–0x07F (global RAM) or 0xF80–0xFFF (special function registers).
Project ButtLoad offers free plans to convert the Butterfly into a portable AVR-ISP for programming other AVR devices. [4] Several plans are available on the web to convert a Butterfly into an MP3 player. [5] C Programming for Microcontrollers, a book for learning to program AVRs using C, was written for the Butterfly as development platform ...
The first of these, the Basic Assembly Language (BAL), is an extremely restricted assembly language, introduced in 1964 and used on 360 systems with only 8 KB of main memory, and only a card reader, a card punch, and a printer for input/output, as part of IBM Basic Programming Support (BPS/360).
AVR32 is a 32-bit RISC microcontroller architecture produced by Atmel.The microcontroller architecture was designed by a handful of people educated at the Norwegian University of Science and Technology, including lead designer Øyvind Strøm and CPU architect Erik Renno in Atmel's Norwegian design center.
