One embodiment provides a processor comprising first circuitry to decode an instruction into a decoded instruction, the instruction to indicate a first source operand and a second source operand and second circuitry including a processing resource to execute the decoded instruction, wherein responsive to the decoded instruction, the processing resource is to output a result of first source operand data minus second source operand data in response to a determination by the processing resource that the first source operand data is greater than or equal to the second source operand data, otherwise the processing resource is to output the first source operand data.

Conditional modular subtraction instruction

An example private processing pipeline may include: a masked decryption unit to perform a masked decryption operation transforming input data into masked decrypted data; a masked functional unit to produce a masked result by performing a masked operation on the masked decrypted data; and a masked encryption unit to perform a masked encryption operation transforming the masked result into an encrypted result.
