  2. Instruction set architecture - Wikipedia

    en.wikipedia.org/wiki/Instruction_set_architecture

    Some instructions give one or both operands implicitly, such as by being stored on top of the stack or in an implicit register. If some of the operands are given implicitly, fewer operands need be specified in the instruction. When a "destination operand" explicitly specifies the destination, an additional operand must be supplied.

  3. Comparison of instruction set architectures - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_instruction...

    The number of operands is one of the factors that may give an indication about the performance of the instruction set. A three-operand architecture (2-in, 1-out) will allow A := B + C to be computed in one instruction ADD B, C, A A two-operand architecture (1-in, 1-in-and-out) will allow A := A + B to be computed in one instruction ADD B, A

    For example, Nikolai Durov defines his generalized rings as monoid objects in the monoidal category of endofunctors on that commute with filtered colimits. [10] This is a generalization of a ring since each ordinary ring R defines a monad Σ R : SetSet {\displaystyle \Sigma _{R}:{\textbf {Set}}\to {\textbf {Set}}} that sends a set X to the ...

  5. PDP-11 architecture - Wikipedia

    en.wikipedia.org/wiki/PDP-11_architecture

    A branch instruction is typically preceded by a two-operand CMP (compare) or BIT (bit test) or a one-operand TST (test) instruction. Arithmetic and logic instructions also set the condition codes. In contrast to Intel processors in the x86 architecture , MOV instructions set them too, so a branch instruction could be used to branch depending on ...

  6. Orthogonal instruction set - Wikipedia

    en.wikipedia.org/wiki/Orthogonal_instruction_set

    Instructions included an address for the operand. For instance, an ADD address instruction would cause the CPU to retrieve the number in memory found at that address and then add it to the value already in the accumulator. This very simple example ISA has a "one-address format" because each instruction includes the address of the data. [4]

  7. Out-of-order execution - Wikipedia

    en.wikipedia.org/wiki/Out-of-order_execution

    The first machine to use out-of-order execution was the CDC 6600 (1964), designed by James E. Thornton, which uses a scoreboard to avoid conflicts. It permits an instruction to execute if its source operand (read) registers aren't to be written to by any unexecuted earlier instruction (true dependency) and the destination (write) register not be a register used by any unexecuted earlier ...

    For example, if you’ve already set aside $25,000 in a savings account, you could open a six-month CD with an annual percentage yield (APY) of 4.50 percent and withdraw $556.31 in interest ...

  9. Compressed instruction set - Wikipedia

    en.wikipedia.org/wiki/Compressed_instruction_set

    The resulting instruction set has real-world limitations; for instance, it can only perform two-operand math of the form A = A + B, whereas most processors of the era used the three-operand format, A = B + C. By removing one operand, four bits are removed from the instruction (there are 16 registers, needing 4 bits), although this is at the ...
