Abstract
Certain exemplary embodiments can provide a programmable logic controller, which can comprise a Reduced Instruction Set Computer (RISC) processor. The RISC processor can be adapted to, responsive to a received request to process a Boolean operation, execute a single processor data access instruction addressed to a region of a memory-mapped register corresponding to the Boolean operation.
Claims17
A system comprising:
- a Reduced Instruction Set Computer (RISC) processor adapted to, responsive to a received request to process a Boolean operation, execute a single processor data access instruction addressed to a region of a memory-mapped register corresponding to said Boolean operation.
A method comprising:
- at a programmable logic controller, responsive to a received request to process a Boolean operation, executing a single processor data access instruction addressed to a region of a memory-mapped register corresponding to said Boolean operation.
A machine-readable medium comprising machine-implementable instructions for activities comprising:
- responsive to a received request to process a Boolean operation, executing a single processor data access instruction addressed to a region of a memory-mapped register corresponding to said Boolean operation.
A system comprising:
- an Application Specific Integrated Circuit (ASIC) comprising a Reduced Instruction Set Computer (RISC) processor adapted to, responsive to a received request to process a Boolean operation, execute a single processor data access instruction addressed to a region of a memory-mapped register corresponding to said Boolean operation, said processor comprised by a programmable logic controller.
