In 8085 Instruction set, ANI is a mnemonic, which stands for “ANd Immediate with Accumulator” and “d8” stands for any 8-bit or 1-Bytedata. This instruction is used to AND 8-bit immediate data with the Accumulator’s content. The result of this ANDingoperation will be stored in the Accumulator itself over writing its previous content. As it is an arithmetic operation do S, P, and Z flags are affected based on the result. Cy is reset to 0, and AC is set to 1. It occupies 2-Bytes in the memory. Mnemonics, Operand Opcode(in HEX) Bytes ANI Data E6 ... Read More
In 8085 Instruction set, ORA is a mnemonic, which stands for “OR Accumulator” and “R” stands for any of the following registers, or memory location M pointed by HL pair. R = A, B, C, D, E, H, L, or M This instruction is used to OR contents of R with the Accumulator. The result of OR operation will be stored back in the Accumulator. As R can have any of the eight values, there are eight opcodes for this type of instruction. It occupies only 1-Byte in memory. Mnemonics, Operand Opcode(in HEX) Bytes ... Read More
The Template matching is a technique, by which a patch or template can be matched from an actual image. This is basically a pattern matching mechanism. In Python there is OpenCV module. Using openCV, we can easily find the match. So in this problem, the OpenVC template matching techniques are used. To use the OpenCV functionality, we need to download them using pip. sudo pip3 install opencv-python For template matching task, there is an accuracy factor, this factor is known as threshold. As an example, we can say that we can easily create face recognizing scheme using this ... Read More
In 8085 Instruction set, ORI is a mnemonic that stands for “OR Immediate with Accumulator” and “d8” stands for any 8-bit data. This instruction is used to OR 8-bit immediate data with the Accumulator. The result of ORing will be stored in the Accumulator itself. As it is a logical instruction, the S, P, and Z flags are affected based on the result. Cy and AC are reset to 0. It occupies 2-Bytes in memory. Mnemonics, Operand Opcode(in HEX) Bytes ORI Data F6 2 Let us consider ORI CDH as an example instruction ... Read More
In 8085 Instruction, XRA is a mnemonic that stands for “eXclusive OR Accumulator” and “R” stands for any of the following registers, or memory location M pointed by HL pair. R = A, B, C, D, E, H, L, or M This instruction is used to Ex-OR contents of R with the Accumulator. The result of Ex-OR operation will be stored in the Accumulator. As R can have any of the eight values, there are eight opcodes for this type of instruction. It occupies only 1-Byte in memory. Mnemonics, Operand Opcode(in HEX) Bytes ... Read More
All arrays consist of contiguous memory locations. The lowest address corresponds to the first element and the highest address to the last element. To initialize an array, first you need to declare it. int[] marks; Here, int is the datatype [] specifies the size of the array Marks is the name of the array Now let us initialize the array using the new keyword. int[] marks = new int[10]; Now let us assign elements to it. marks[0] = 96; marks[1] = 90 You can also assign elements like this − int [] marks = new int[10] { 78, 67, 88, 56, 90, 77, 76, 70, 60, 70};
In 8085 Instruction set, XRI is a mnemonic that stands for “eXclusive OR Immediate with Accumulator” and “d8” stands for any 8-bit data. This instruction is used to Ex-OR 8-bit immediate data with the Accumulator. The result of Ex-ORing will be stored in the Accumulator overwriting its previous content. As it is a Logical instruction, so S, P, and Z flags are affected based on the result thus produced. Cy and AC are reset to 0. It occupies 2-Bytes in memory during execution. Mnemonics, Operand Opcode(in HEX) Bytes XRI Data EE 2 Let ... Read More
The class method in Python is a method, which is bound to the class but not the object of that class. The static methods are also same but there are some basic differences. For class methods, we need to specify @classmethod decorator, and for static method @staticmethod decorator is used. Syntax for Class Method. class my_class: @classmethod deffunction_name(cls, arguments): #Function Body return value Syntax for Static Method. class my_class: @staticmethod deffunction_name(arguments): ...

In 8085 Instruction set, CMC stands for “CoMplement the Carry flag”. It performs complement operation on the cy flag, and the result is stored back in the cy flag. Mnemonics, Operand Opcode(in HEX) Bytes CMC 3F 1 The result of execution of this instruction has been depicted in the following tracing table − Before After (Cy) 1 0 Address Hex Codes Mnemonic Comment 2001 3F CMC Complement of Cy when Cy=1 The timing diagram against this instruction CMC execution is as follows − Summary − So this instruction CMC requires 1-Byte, 1-Machine Cycle (Opcode Fetch) and 4 T-States for execution as shown in the timing diagram.
In this article, we will see how we can send email with attachments using Python. To send mail, we do not need any external library. There is a module called SMTPlib, which comes with Python. It uses SMTP (Simple Mail Transfer Protocol) to send the mail. It creates SMTP client session objects for mailing. SMTP needs valid source and destination email ids, and port numbers. The port number varies for different sites. As an example, for google the port is 587. At first we need to import the module to send mail. import smtplib Here we are also ... Read More
