D.2.1 General
Integer operand sizes are defined as follows:
1.
Byte: 8 bits long
2.
Short word: 16 bits long
3.
Word: 32-bits long
4.
Long word: 64 bits long
The operand size for each instruction is either explicitly encoded in the instruction or implicitly defined by
the instruction.
D.2.2 Integer Storage Format in Memory
The DSP96002 supports four integer memory data formats:
1.
Signed word integer: 32-bits wide, two’s complement representation. This storage format can
be used in either X and/or Y data memory space.
2.
Signed Long Word Integer: 64 bits wide, two’s complement representation. This storage format
can only be used in long (L) data memory space.
3.
Unsigned Word Integer: 32-bits wide with unsigned magnitude representation. This storage for-
mat can be used in either X and/or Y data memory space.
