Abstract:
In a semiconductor device comprising sophisticated high-k metal gate structures formed in accordance with a replacement gate approach, semiconductor-based resistors may be formed above isolation structures (103D) substantially without being influenced by the replacement gate approach. Consequently, enhanced area efficiency may be achieved compared to conventional strategies, in which the resistive structures may have to be provided on the basis of a gate electrode metal, while, nevertheless, a low parasitic capacitance may be accomplished due to providing the resistive structures above the isolation structure.
Abstract:
Encrypting information involving the execution of a first instruction and a second instruction on a processor. The first instruction causes the processor to perform an AddRoundKey transformation followed by a ShiftRows transformation. The second instruction causes the processor to perform a ShiftRows transformation followed by a MixColumns transformation. These instructions are useful for performing AES encryption. The first and second instructions also have inverse modes that may be used to perform AES decryption.

Abstract:
A mechanism for superscalar decode of variable length instructions. A length decode unit may obtain a plurality of instruction bytes based on a scan window of a predetermined size. The instruction bytes may be associated with a plurality of variable length instructions, which are scheduled to be executed by a processing unit. The length decode unit may, for each instruction byte, estimate the start of a next variable length instruction following a current variable length instruction, and store a first pointer. A pre- pick unit may, for each instruction byte, use the first pointer to estimate the start of a subsequent variable length instruction following the next variable length instruction within the scan window, and store a second pointer. A pick unit may use a start pointer and related first and second pointers to determine the actual start of the variable length instructions within the scan window, and generate instruction pointers.
