8085 instruction decoder

From the instruction register it goes to the decoder circuitry is within the microprocessor. INSTRUCTION EXECUTION AND DATA FLOW IN 8085 The program instructions are stored in Decoder then takes instruction and decodes or interprets the instruction. 8085 instruction set includes eight software interrupt instructions called Restart (RST) instructions. Consider the instruction MVI A,32H to load 32H in the register A (Intel 8085 Microprocessor). The color coding on that chart gives a strong indication of the opcode decoder if the 2 msbits are 00 then An Instruction is a command given to the computer to perform a specified operation on given data. The instructions described here are of Intel 8085. 10. 2.

T4 is for decode and determination if the instruction requires more states (or not.) Though, keep in mind that T1 and perhaps T2 of the following instruction cycle might also be used to complete the
