Instruction Set
T he ADSP-2104/ADSP-2109 assembly language uses an algebraic
syntax for ease of coding and readability. T he 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. T he instructions encompass a wide
variety of instruction types along with a high degree of
operational parallelism. T here 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.
T he instruction set is summarized below. T he
