MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202617066334 A) filed by Apple Inc. on May 26, 2026, for Processor Instruction For Secure Pointer Arithmetic.
Inventors include Habouzit, Pierre; Snyder, Michael D.; and Gonion, Jeff.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: An apparatus includes a processor circuit with an execution pipeline circuit configured to execute instructions within an instruction stream, including a first instance of an instruction executable to compute an address to access a data array. The first instance of the instruction may specify a set of operands that includes a pointer to a base address of the data array, an index into the data array, and a size of data elements within the data array. In response to receiving the first instance of the instruction, the execution pipeline circuit may be configured to perform an arithmetic operation that includes a multiplication of the index and the size to generate a result for the address. In response to the arithmetic operation generating an overflow condition, the execution pipeline circuit may be further configured to cause a first corrective action that prevents access to the data array.
