For example, an instruction might have a one-bit opcode followed by a variable-length operand ... have a complex instruction set computer (CISC) architecture, where they have a large number ...

This method is always used as a source operand ... in the opcode map. This is presumably because the operands are treated as integers during the move operation. The newer manuals from the AVX era ...

Opcode Instruction ... in carry flag and set The index of the selected bit can be given by the immediate constant in the instruction or by a value in a general register. Only an 8-bit immediate value ...

This paper introduces PIM Instruction Set Architecture (ISA) using a DMA descriptor called PISA-DMA to express a PIM opcode and operand in a single descriptor. Our ISA makes PIM programming intuitive ...
