What are x86 opcode bytes?

The x86 opcode bytes are 8-bit equivalents of iii field that we discussed in simplified encoding. This provides for up to 512 different instruction classes, although the x86 does not yet use them all. How many bits are needed for the program counter and the instruction register?

What is an opcode table?

2007 by Taylor & Francis Group, LLC. The asse mbler uses an opcode table to extract opcode inf ormation. The op code table is a table storing each mnemon ic, the correspo nding opcode , and any othe r attribut e of the instru ction useful for the asse mbly proce ss.

What is the difference between x86-64 and x87 opcodes?

So when SIB.baseuses a 16-bit register (such as AX), the address size becomes 16-bit. Using a 32-bit displacement will result in the displacement being truncated. Opcode The x86-64 instruction set defines many opcodes and many ways to encode them, depending on several factors. Legacy opcodes Legacy (and x87) opcodes consist of, in this order:
