Assembler Code Content of ROMMOV @R10+,0(R11) MOV @R10+,0(R11) Length: One or two words Operation: Move the contents of the source address (contents of R10) to the destination address (contents of R11). Register R10 is incremented by 1 for a byte o…
Byte and word issues The MSP430 is byte-addressed, and little-endian. Word operands must be located at even addresses 1 Appending “.b” to an instruction makes it a byte operation. A byte instruction with a register destination clears the high 8 bits…

The status register (SR/R2), used as a source or destination register, can be used in the register mode only addressed with word instructions. The remaining combinations of addressing modes are used to support the constant generator.…
Introduction One of the revolutionary features of C++ over traditional languages is its support for exception handling. It provides a very good alternative to traditional techniques of error handling which are often inadequate and error-prone. The cl…
ref:http://www.coranac.com/tonc/text/asm.htm 23.1. Introduction Very broadly speaking, you can divide programming languages into 4 classes. At the lowest level is machine code: raw numbers that the CPU decodes into instructions to execute. One step u…
Intro to the LLVM MC Project The LLVM Machine Code (aka MC) sub-project of LLVM was created to solve a number of problems in the realm of assembly, disassembly, object file format handling, and a number of other related areas that CPU instruction-set…

Processor operations mostly involve processing data. This data can be stored in memory and accessed from thereon. However, reading data from and storing data into memory slows down the processor, as it involves complicated processes of sending the da…
By brant-ruan Yeah, I feel very happy When you want to give up, think why you have held on so long. Just fight. Somebody may ask you: Why would you want to do that? Yeah, because I want to know how it works. Assembly language programming is about mem…
