Type of Microprocessor :
Microprocessors fall into 3 categories:
The general purpose microprocessor have ALU with 1 or more then 1 registers which functioned as, a control unit, accumulator ,an instruction decoder which handled a fixed instruction set special and general purpose registers which varied significantly from microprocessor to microprocessor. A microprocessor can have an internal stack of fixed length or use external memory for stack. The general purpose microprocessor is available of word lengths of 16, 32, 16, 8, 4, and 1 bit.
The Bit slice microprocessor divide the functions of ALL, special purpose and general purpose registers and control unit into many ICs. For this ALU and general purpose registers were packed in separately from controls. Each register of ALU (RALU) package was really equivalent to 2 or 4-bit wide slice of registers and the ALU of the microprocessor. Bit slice processor might be cascaded to produce any unconventional or conventional word length of the microprocessor such as 4, 8, 10, 12, 16, 32 or higher bits. The control portion of bit slice processor was constructed from microprocessor sequencer IC and other logics.
The modes are determined by the contents of the control register, whose format is given in Figure These modes are: Mode 0: If a group is in mode 0, it is divided into 2 sets.
a- Trace the following program fragment and find out the content of ax after the the execution of the program. X db 5,7 -3,-9,4,-7,9 Mov
CBW: Convert Signed Byte to Word: This instruction converts a signed byte to a signed word. In other terms, it copies the sign bit of a byte to be converted to all of the bits in
Example : Add the contents of the 2000H: 0500H memory location to contents of 3000H: 0600H and store the result in 5000H: 0700H. Solution : Unlike the past example progra

Program : Write an assembly program to find out the largest number from a given unordered array of 8-bit numbers that stored in the locations starting from a known address. S
Program Translation Sequence Developing a software program to accomplish a particular task, the implementer chooses an appropriate language, develops the algorithm (a sequence
LABEL : The Label directive which is used to assign a name to the current content of the location counter. At the beginning of the assembly process, the assembler start a loca
