Color game using Tkinter in Python
For developing GUI applications tkinter is very popular and easy. Using tkinter easily develop GUI games. Here also we are trying to develop color game. In this game the player has to enter color of the word that appears on the screen and hence the score increases by one, the total time to play this game is 30 seconds and colors used in this game are Red, Blue, Green, Pink, Black, Yellow, Orange, White, Purple and Brown. The interface will display name of different colors in different colors. User has to identify the color and enter the correct color name ...
Read MorePython program maximum of three.
Given three number a b and c, our task is that we have to find the maximum element in among in given number. Example Input: a = 2, b = 4, c = 3 Output: 4 Algorithm Step 1: input three user input number. Step2: Add three numbers to list. Step 3: Using max() function to find the greatest number max(lst). Step 4: And finally we will print maximum number. Example Code def maximum(a, b, c): list = [a, b, c] return max(list) # ...
Read MoreInstruction type SUB R in 8085 Microprocessor
In 8085 Instruction, SUB is a mnemonic that stands for ‘SUBtract contents of R from Accumulator. Here 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 Mnemonics, Operand Opcode(in HEX) Bytes SUB A 97 1 SUB B 90 1 SUB C 91 1 SUB D 92 1 SUB E 93 1 SUB H 94 1 SUB L 95 1 SUB M ...
Read MoreInstruction type DCR R in 8085 Microprocessor
In 8085 Instruction set, DCR is a mnemonic, which stands for ‘DeCRement’ 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 decrease the content of register R. Also we can say it will subtract 1 from the register R content. And the decremented value will be stored on to the register R itself. As it is an arithmetic instruction, so all flags, except Cy flag, are affected depending on the result. In those assembly ...
Read MoreInstruction type DCX rp in 8085 Microprocessor
In 8085 Instruction set, DCX is a mnemonic that stands for “DeCrementeXtended register” and rp stands for register pair. And it can be any one of the following register pairs − rp = BC, DE, or HL This instruction will be used to subtract 1 from the present content of the rp. And thus the result of the decremented content will remain stored in rp itself. Though, it is an arithmetic instruction, note that flags are not at all affected by the execution of this instruction. A register pair is generally used to store 16-bit memory address. If ...
Read MoreInstruction type ANA R in 8085 Microprocessor
In 8085 Instruction set, ANA is a mnemonic, which stands for “ANd Accumulator” and “R” stands for any one 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 AND contents of R with Accumulator’s content. The result thus produced for this AND operation will be stored back in to the Accumulator over writing its previous content. As R can have any of the eight values, there are eight opcodes for this type of instruction. It occupies only 1-Byte in ...
Read MoreInstruction type ORA R in 8085 Microprocessor
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 MoreInstruction type XRA R in 8085 Microprocessor
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 MoreInstruction type CMC in 8085 Microprocessor
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.
Read MoreInstruction type CMP R in 8085 Microprocessor
In 8085 Instruction set, CMP is a mnemonic that stands for “CoMPareAccumulator” and hereR 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 compare contents of the Accumulator with given register R. The result of compare operation will be stored in the Temp register. Temp is not a GPR (General Purpose Register) but an internal register that is not accessible to the programmer. Actually R register’s content will get subtracted from Accumulators content and difference value ...
