Seven basic types are supported. These data types are:
• Bits
• Bits Flieds (String of consecutive bits, 1-32 bits long)
• BCD Digits (Packed: 2 digits/byte, Unpacked: 1 digit/byte)
• Byte Integers (8-bit)
• Word Integers (16-bit)
• Long Word Integers (32-bit)
• Quad Word Integers (64-bit)
In addition, operations on other data types, such as memory addresses, status word
data, etc...., are provided in the instruction set. The co-processor mechanism allows
direct support of floating-point data type with the TS68881 and TS68882 floating-point
co-processors, as well as specialized user-defined data types and functions.
