The instruction types are grouped into four categories:
•
•
•
•
The instruction types are numbered; there are 22 types. Some instructions have more
than one syntactical form; for example, Instruction 4 has four distinct forms. The instruc-
tion number itself has no bearing on programming, but corresponds to the opcode
recognized by the TSC21020F device.
Because of the width and orthogonality of the instruction word, there are many possible
instructions. For example, the ALU supports 21 fixed-point operations and 24 floating-
point operations; each of these operations can be the compute portion of an instruction.
The following pages provide an overview and summary of the TSC21020F instruction
set. For complete information, see the ADSP-21020 User's Manual from Analog
Devices. For additional reference information, see the ADSP- 21020 Programmer's
Quick Reference from Analog Devices.
This section also contains several reference tables for using the instruction set.
