Abstract: Techniques for debugging errors in a processor are disclosed. One or more processors are accessed. Each processor within the one or more processors includes a set of assertion registers. A processor within the one or more processors executes one or more instructions. An assertion logic detects an error condition in the processor. The detecting occurs during the executing. The error condition is recorded. The recording is based on one or more bits in the set of assertion registers. A hardware interface reads the one or more bits in the set of assertion registers. The one or more bits indicate the error condition to the hardware interface. The executing includes a communication protocol between the processor and a slave device. The error condition comprises an incorrect value in a credit buffer. The credit buffer controls a number of transactions allowed between the processor and the slave device.

Abstract: Disclosed embodiments provide techniques for instruction execution with a processor pipeline for data transfer operations. A processor core is accessed. The processor core executes one or more instructions out of order. The processor core supports integer operations and floating-point operations. An instruction in the processor core is decoded. The instruction is a data transfer operation. The data transfer operation necessitates a floating-point operation and an integer operation. The floating-point operation and the integer operation are dispatched to one or more issue queues. The floating-point operation and the integer operation are interlocked. The interlocking is accomplished using at least one entry in the one or more issue queues. A first operation of the floating-point operation and the integer operation is executed. A second operation of the floating-point operation and the integer operation is executed. The execution of the second operation is based on the interlocking.

Abstract: Disclosed embodiments provide techniques for instruction execution in computer processors. A dispatch unit dispatches instructions to one or more issue queues. Instructions from the issue queues feed into execution pipelines. Each execution pipeline includes instruction queue control logic, and two execution engines. A first execution engine is assigned to variable latency instructions while a second execution engine is assigned to fixed latency instructions. While a variable latency instruction executes, fixed latency instructions can be issued, executed, and completed. When the variable latency instruction finishes execution, a request is issued by the first execution engine to the instruction queue control logic. In response, the instruction queue control logic introduces a stall in a common write-back pipeline, allowing the variable latency instruction to complete. The result of the variable latency instruction is provided to a depending fixed latency instruction via a bypass path.

Abstract: Disclosed techniques enable processors that are capable of performing a wide range of vector operations. A processor can support multiple types of instructions. The instructions can include one or more operands, and the one or more operands can include different data types. An A-type instruction can have dependencies on a B-type instruction. An A-type instruction includes a vector instruction. A B-type instruction includes an integer instruction or a floating-point instruction. A datapath is provided to enable intermediate results from a B-type instruction to be supplied to the A-type instruction on which it depends, without utilizing register file resources, such as general-purpose register (GPR) register resources. Vector instruction performance is thereby enabled without the additional resources used with GPR register access.

Abstract: Techniques for instruction execution based on processor instruction exception handling are disclosed. A processor core is accessed. The processor core executes at least one instruction thread. The processor core executes one or more instructions out of order. An ordered list of instructions is maintained. The ordered list is based on instructions that are presented to the processor core for execution. The ordered list is organized using one or more pointers. An execution exception is detected in the processor core. The execution exception corresponds to one of the instructions in the ordered list. The execution exception requires initiating an exception handling routine. An effective age of an instruction in the ordered list is determined. The effective age corresponds to the execution exception. The exception handling routine is initiated, based on matching the effective age of an instruction in the ordered list with one of the one or more pointers.

The foam insert assembly may be configured to conformally encapsulate one or more shipping items within the interior portion of the shipping container, e.g., so as to protect the one or more shipping items from mechanical impact damage (e.g., bending) and/or environmental damage (e.g., exposure to moisture) during shipping.

Abstract: The present invention discloses an industrial scale method to obtain 1-kestose by the use of a recombinant fructosyltransferase (FTF), isolated from Festuca arundinacea, expressed constitutively in a non-saccharolytic yeast. In this invention, the recombinant FTF type sucrose:sucrose 1-fructosyltransferase (1-SSTrec) is produced constitutively, stable and at high yield, both in the culture supernatant and in intact cells of the host Pichia pastoris. Hence, the invention additionally provides a method for 1-SST production at industrial scale. The recombinant enzyme is then used for mass production of short-chain fructooligosaccharides (FOS), specifically 1-kestose, from sucrose. The method of the present invention establishes conditions that allow conversion rates where the synthesized FOS constitute above 55% (w/w) of the total sugars in the reaction mixture and the 1-kestose content reaches values higher than 90% (w/w) of the total FOS fraction.
