The Z80 has several "undocumented" opcodes that were not in the original manual but function perfectly on the silicon.
Let’s look at how a disassembler interprets the byte sequence: DD 36 05 3C z80 disassembler
Despite these, recursive descent is the gold standard for Z80 disassemblers. The Z80 has several "undocumented" opcodes that were
A Z80 disassembler typically performs the following tasks: z80 disassembler
To write a disassembler, one must first understand the encoding of the instructions. Unlike modern RISC architectures with fixed instruction widths, the Z80 is a CISC (Complex Instruction Set Computer) architecture with variable-length instructions.
The disassembler reads the current byte. If the byte corresponds to a standard instruction (unprefixed), it prints the mnemonic and consumes the appropriate number of operand bytes.
