Log In Sign Up. Basic functional units of a computer. Connections between the processor and the memory. Main Cache memory memory Processor Bus Figure 1. Addition of 1 – bit numbers. Sarath and word Chandran. Sarath A straight-line program for adding n numbers. Using a loop to add n numbers. Use of indirect addressing in the program of Figure 2.

ccs2253 A list of students’ marks. After accessing the operand, the contents of this register are automatically incremented to point to the next item in a list. The increment is 1 for byte-sized operands, 2 for bit operands, and 4 for bit operands.

The Autoincrement addressing K. Sarath mode used in the program of Figure 2. It then sends the second character. Input is sent from the keyboard in a similar way. No special instructions are needed. Also use device status registers. Also, increment the pointer to store the next character. A program that reads a line of characters and displays it.


A stack of words in the memory. Effect of stack operations on the stack in Figure 2. If it does,the stack is empty. If it does, the stack is full. Checking for empty and full errors in pop and push operations. Subroutine linkage using a link notse. Program of Figure 2.

Add 8,SP Restoretop of stack top of stack at level 1. Clear R0 Initialize sum to 0. Page 76 K. Such space is called a stack frame. LShiftL 4,R1 Shift left by 4 bit positions. A routine that packs two BCD digits. Move N,R3 R3 serves as a counter. Clear R0 R0 accumulates the dot product. Add R4,R0 Add to previoussum. Decrement R3 Decrement thecounter. A program for computing the dot product of two vectors. The first bit is 0. A subroutine for deleting a record from a linked list.
