TIS Advanced
TIS Advanced features include two new modules, and several new instructions for the Execution Module.
New Modules
New Instructions for Execution Module
Floating Point Arithmetic Instructions
ADDF
, SUBF
, MULF
, and DIVF
behave like their integer counterparts, however, they operate on ACC
as though the data contained within represents an IEEE-754 compliant half-precision floating point number.
Note that it is possible to store an integer value in ACC
and attempt floating point calculations on it, and vice versa. This is likely to produce incorrect values. It is the user's responsibility to ensure that operations are only performed on the correct data representation.
Floating Point Flow Control Instructions
The JEZF
, JNZF
, JGZF
, and JLZF
instructions behave like their integer counterparts JEZ
, JNZ
, JGZ
, and JLZ
, however, like the floating point arithmetic operations above, they operate on ACC
as though the value contained within is an IEEE-754 half-precision float.
Floating Point Conversion Instructions
The FLT
instruction will convert an integer value stored in ACC
to a IEEE-754 half-precision floating point representation. The INT
instruction will convert a floating point value stored in ACC
to a 16-bit signed two's complement integer representation; the same representation used by standard TIS-3D arithmetic operations. Converting to integer representation will round the floating point value to the nearest whole number, with ties rounding upwards.
MOV
Instruction Changes
The MOV
instruction has been extended to support handling floating point literals. For example, the instruction MOV 0.25 ACC
will no longer be a compiler error, and will now load the floating point value 0.25
into the ACC
register as expected.
