- Some other machines that have conditional assignment instructions:
-
- 1- The IBM TJWatson VLIW, developed by K.Ebcioglu. Its instructions
- are best represented as a tree such as
-
- if cc1 then
- R1=R2+R3
- else if cc2
- ` R2=R3+R4
- else
- R3=R4+R5
-
- In other words, it allows for some form of ANDing of condition codes
- to be specified on the (long) instruction.
-
- 2- The SIGNETICS LIFE processor: there, every opcode has a third (boolean)
- input. It also is a VLIW
-
- 3- The Multiflow TRACE has a "conditional assignment" opcode
-
