Negative displacement Example Since displacement can be negative as represented in 2’s complement form move d3, $FFFC(a0) If a0 = 0000 0008 EA = 0000 0008 (a0) + FFFF FFFC (sign-extended displ) 0000 0004 Therefore, according to the instruction, low-order word of d3 moves to memory location $000004 a0 and d3 remain unchanged. ENG3640 Microcomputer Interfacing - . Machine language is the only language a computer is capable of understanding. (Contd) Readability of assembly language instructions is much better than the machine language instructions Machine language instructions are a sequence of 1s and 0s. Assembly language was developed to overcome some of the many inconveniences of machine language. Some programs really are developed at this low level, but the program-mers use “assembly language”, which lets them use names rather than numbers, and helps in other ways as well. Create stunning presentation online in just 3 steps. AS English Language - . DEVELOPMENT ENVIRONMENT. Such languages are abbreviated as ‘asm’ and there is usually a very close link between the language and the machine code instructions of the architecture.

Machine language a program that consists of 0s and 1’s. • Machine language and Assembly language are both –Microprocessor specific (Machine dependent) so they are called –Low-level languages • Machine independent languages are called –High-level languages –For e.g. This is another low-level but very important language in which operation codes and operands are given in the form of alphanumeric symbols instead of 0’s and l’s. – Assembly language is a symbolic representation of machine code. The instruction in machine language would look something like below: If addresses are explicitly defined as part of the machine language, the instruction becomes too long (2 words instead of 1 word), and accessing the instruction would require more memory accesses. A machine language instruction has two parts. Programmers must know all details of the CPU. but first!. this section of the course is about language ... the vehicle for holding and transmitting, Assemblers and Linkers - .
