Devices and methods for determining analyte levels are described. The devices and methods allow for the implantation of analyte-monitoring devices, such as glucose monitoring devices, that result in the delivery of a dependable flow of blood to deliver sample to the implanted device. The devices comprise a unique microarchitectural arrangement in the sensor region that allows accurate data to be obtained over long periods of time.

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 processor framework includes a compiler which compiles a computer program, the compiler extracting speculative static information about memory accesses during compilation, and a microarchitecture which performs a memory access using the speculative static information extracted during compiling. An instruction set architecture encodes information about accessing the memory at run time and selects access mechanisms to perform an individual memory access.

Described are drug delivery systems incorporating electrospun fibers that comprise and deliver physicochemically diverse drug compounds. Such fibers provide significant advantages in drug agent release, such as adaptability for solid dosage delivery to mucosal tissues. This is in addition to allowing for controlled drug release. Systems and methods for large-scale electrospinning productivity are described, including novel microarchitectures allowing for variable pharmacokinetics in drug release.

The microarchitecture of the arithmetic unit includes two cascaded N bit adders to provide an N bits result in an accumulator. The arithmetic unit also includes a carry save adder, followed by an adder, which, along with the accumulator, are extended to N+1 bits. A circuit for determining the output carry value associated with the result is also provided.

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.

A computer-implemented method and a system for managing power in a multi-core microprocessor are provided. A power management control microarchitecture in a chiplet translates a first command comprising a power setting. A chiplet comprises a processor core and associated memory cache. The power management control microarchitecture comprises power mode registers, power mode adjusters, translators, and microarchitectural power management techniques. The power management control microarchitecture sets microarchitectural power management techniques according to the power setting. The global power management controller issues the first command. The global power management controller may reside either on or off of the microprocessor. The global power management controller issues commands either directly for a specific chiplet out of the plurality of chiplets or to the plurality of chiplets and the control slave bus translates the command into sub-commands dedicated to specific chiplets within the plurality of chiplets. Each chiplet may be set to separate power levels.

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.

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).

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.

By the system and the method, the microarchitecture data indexes of the computing nodes and the data indexes of the processes of the running applications are acquired, so that intelligent big data analysis is realized, the faulted computing nodes are positioned automatically, and fault causes are provided.

Microarchitecture policies and structures partition execution resource clusters. In disclosed microarchitecture embodiments, micro-operations representing a sequential instruction ordering are partitioned into a two sets. To one set of micro-operations execution resources are allocated from a cluster of execution resources that can perform memory access operations but not branching operations. To the other set of micro-operations execution resources are allocated from a cluster of execution resources that can perform branching operations but not memory access operations. The first and second sets of micro-operations may be executed out of sequential order but are retired to represent their sequential instruction ordering.
