opcode

The other parts of the instruction are the opcode, and destination.

And a term that probably everybody has heard is opcode, the operation code.

Add it to the given number to obtain the corresponding opcode.

The opcode used indicated the history of that particular branch instruction.

Note that most of the instructions used occupy a single 8-bit opcode.

However, it does not have any special opcode to read values index registers.

Because there were only three bits for the opcode.

And mostly what I loved is, like, well, you don't need an opcode.

The last 3 forms use bit 4 as an additional opcode bit.

The opcode is also present on the 6809.

Often, one group of numbers in the instruction, called the opcode, indicates which operation to perform.

An opcode identifies which basic computer operation in the instruction set is to be performed.

Each machine language instruction typically has both an opcode and operands.

The first three bits of the 12-bit word is the opcode, meaning there's eight of them.

A 7-bit function field follows, which is used in conjunction with the opcode to specify an operation.

Only a 5-bit opcode was used in order to simplify the basic logic and gain an address bit.

The programmer must only remember a mnemonic for each opcode instead of its binary value.

Most instructions have one or more opcode fields.

So if we had an opcode of, say, 5 bits, well, we know how binary works.

I booted from the CD and got an opcode error.

Each instruction is stored on 16 bit's, the first 4 are the Opcode and the other 12 are the address field.

Each instruction is made up of an opcode (operation code) and operand(s).

They are contained in the opcode itself.

And sort of traditionally, the opcode has been on the left of one of these long words.

So, for example, in the case of this computer we're making, we'll dedicate some number of bits to the opcode.
