A multiple clock domain (MCD) microarchitecture uses a globally-asynchronous, locally-synchronous (GALS) clocking style. In an MCD microprocessor each functional block operates with a separately generated clock, and synchronizing circuits ensure reliable inter-domain communication. Thus, fully synchronous design practices are used in the design of each domain.

The poor scalability of existing superscalar processors has been of great concern to the computer engineering community. In particular, the critical-path delays of many components in existing implementations grow quadratically with the issue width and the window size. This patent presents a novel way to reimplement these components and reduce their critical-path delay growth. It then describes an entire processor microarchitecture, called the Ultrascalar processor, that has better critical-path delay growth than existing superscalars. Most of our scalable designs are based on a single circuit, a cyclic segmented parallel prefix (cspp). We observe that processor components typically operate on a wrap-around sequence of instructions, computing some associative property of that sequence. For example, to assign an ALU to the oldest requesting instruction, each instruction in the instruction sequence must be told whether any preceding instructions are requesting an ALU. Similarly, to read an argument register, an instruction must somehow communicate with the most recent preceding instruction that wrote that register. A cspp circuit can implement such functions by computing for each instruction within a wrap-around instruction sequence the accumulative result of applying some associative operator to all the preceding instructions. A cspp circuit has a critical path gate delay logarithmic in the length of the instruction sequence. Depending on its associative operation and its layout, a cspp circuit can have a critical path wire delay sublinear in the length of the instruction sequence.

A parallel object detection method for heterogeneous microarchitectures. The method is designed for increasing the throughput of object detection in a computer system that is equipped with an array of cores including a shared memory, a constant memory, and functional units. Latency reduction is achieved through a multilevel parallelization method that exploits fine-grain data-level parallelism using multithreaded SIMD computations, and coarse-grain parallelism by relying on concurrent kernel execution.

Testcases are run to test the design of an integrated circuit. The coverage of the testcases is evaluated and compared against one or more microarchitecture models that define the behavior of a portion of the integrated circuit. If the coverage of the testcases is not adequate, new testcases are generated to test the previously untested behavior specified in the microarchitecture models.

The microprocessor includes an instruction translator that translates a macroinstruction of a macroinstruction set in its macroarchitecture into exactly three microinstructions to perform a read / modify / write operation on a memory operand. The first microinstruction instructs the microprocessor to load the memory operand into the microprocessor from a memory location and to calculate a destination address of the memory location. The second microinstruction instructs the microprocessor to perform an arithmetic or logical operation on the loaded memory operand to generate a result. The third microinstruction instructs the microprocessor to write the result to the memory location whose destination address is calculated by the first microinstruction. A first execution unit receives the first microinstruction and responsively loads the memory operand into the microprocessor from the memory location, and a second distinct execution unit also receives the first microinstruction and responsively calculates the destination address of the memory location.

To provide hardware protection against timing based side channel attacks, a processor's microarchitecture enables an OS to determine which applications have the privilege to read timestamp and performance counters. Using a white list of applications, and an authentication mechanism to authenticate applications, a legitimate Protection Required Application (PRA) may temporarily prevent other applications from reading timestamp and performance counters while it executes (or excutes sensitive operations).

Reclaiming checkpoints in a system in an order that differs from the order when the checkpoints are created. Reclaiming the checkpoints includes: creating one or more checkpoints, each of which having an initial state using system resources and holding the checkpoints state; identifying the completion of all the instructions associated with the checkpoint; reassigning all the instructions associated with the identified checkpoint to an immediately preceding checkpoint; and freeing the resources associated with the identified checkpoint. The checkpoint is created when the instruction that is checked is a conditional branch having a direction that cannot be predicted with a predetermined confidence level.

Various novel block cationomers comprising polyisobutylene (PIB) and poly(2-dimethylamino)ethyl methacrylate) (PDMAEMA) segments have been synthesized and characterized. The specific targets were various molecular weight diblocks (PDMAEMA+) and triblocks (PDMAEMA+-b-PIB-b-PDMAEMA+) with the PIB blocks in the DPn=50-200 (Mn=3,000-9,000 g / mol) range connected to blocks of PDMAEMA+ cations in the DPn=5-20 range. The overall synthetic strategy for the preparation of these block cationomers comprised four steps: 1) Synthesis by living cationic polymerization of mono- and di-allyltelechelic polyisobutylenes, 2) End group transformation to obtain PIBs fitted with termini capable of mediating the atom transfer radical polymerization (ATRP) of DMAEMA, 3) ATRP of DMAEMA and 4) Quaternization of PDMAEMA to PDMAEMA+I− by CH3I. Kinetic and model experiments provided guidance to develop convenient synthesis methods. The microarchitecture of PIB-PDMAEMA di-and triblock and the corresponding block cationomers were confirmed by 1H NMR and FTIR spectroscopy and solubility studies.

A microarchitecture and instruction set that supports multiple, simultaneously executing threads. The approach is disclosed in regard to its applicability in connection with a recently developed microarchitecture called “WaveScalar.” WaveScalar is a compiler that breaks a control flow graph for a program into pieces called waves having instructions that are partially ordered (i.e., a wave contains no back-edges), and for which control enters at a single point. Certain aspects of the present approach are also generally applicable to executing multiple threads on a more conventional microarchitecture. In one aspect of this approach, instructions are provided that enable and disable wave-ordered memory. Additional memory access instructions bypass wave-ordered memory, exposing additional parallelism. Also, a lightweight, interthread synchronization is employed that models hardware queue locks. Finally, a simple fence instruction is used to allow applications to handle relaxed memory consistency.
