Abstract: ABSTRACT    A PC program editing system for editing a sequence program of a PC (programmable controller).  The symbols of signals from the sequence program are dividedly stored in a first symbol table (5a) and a second symbol table (5b) by a programming apparatus (1).  The sequence program and the symbols stored in the first symbol table (5a) are transferred to the PC (PMC), and the sequence program is edited by the PC (PMC).  In this case, the execution of the editing is centered around the signals of the symbols stored in the first symbol table (5a).  If necessary, the sequence program is returned to the programming apparatus (1), the symbols in the first symbol table (5a) are replaced with the symbols of signals to be edited next, and the sequence program, together with this symbol table, is again transferred to the PC (PMC) to be edited.  Accordingly, the sequence program can be edited by a PC (PMC) with a small symbol storage area.
Patent CA-2031112-A1 (CA)
Inventor: KING STEPHEN E
IPC: G06F9/45
Filed: 1990-11-29
Abstract: A compiler module is disclosed which minimizes pipeline breaks  by  reordering  object  code  instructions  to  avoid conflicts between closely grouped instructions to the extent possible.  Representation of each object code instruction in a small sequential group is temporarily held in a buffer and is assigned a pair of Attribute Words.  Potential conflicts which  a  newly  called instruction  may  have  with  those instructions  already  in  the  buffer  are  ascertained  by logically AND-ing  its Attribute Words with those of  the other instructions and examining the result.  If a conflict does exist, an attempt is made to resolve it by determining if the conflicting instruction already in the buffer can be moved ahead of one or more other instructions in the buffer such that the conflict is eliminated or minimized.   This procedure involves a comparison of the Attribute Words of the candidate instruction to be moved, Im, with the other instructions in the buffer.  If movement of the conflicting instruction is possible and will resolve or minimize the conflict, the instructions in the buffer are reordered as appropriate.
