Instruction Set
The ADSP-21xx assembly language uses an algebraic syntax for
ease of coding and readability. The sources and destinations of
computations and data movements are written explicitly in each
assembly statement, eliminating cryptic assembler mnemonics.
Every instruction assembles into a single 24-bit word and
executes in a single cycle. The instructions encompass a wide
variety of instruction types along with a high degree of
operational parallelism. There are five basic categories of
instructions: data move instructions, computational instruc-
tions, multifunction instructions, program flow control instruc-
tions and miscellaneous instructions. Multifunction instructions
perform one or two data moves and a computation.
The instruction set is summarized below. The ADSP-2100
Family Users Manual contains a complete reference to the
instruction set.
