An exercise device for lifting up the lower back by raising a user's knees upward from a resting position. An elongated fixed strut extends upward from the base, and a carriage is placed on the elongated fixed strut, capable of moving on the elongated fixed strut between a lower position and an upper position relative to the elongated fixed strut. Knee supports are attached to the carriage, allowing a user to place their knees on the knee supports. As the carriage moves upward on the elongated fixed strut, the user's knees are lifted upward, thereby causing the hips and pelvis to rise, producing a flexion of the lower back. The upward movement of the hips and pelvis produces the distraction of the lumbar spinal segments.

Exercise device and method of use

Techniques for providing improved data distribution to and collection from multiple memories are described. Such memories are often associated with and local to processing elements (PEs) within an array processor. Improved data transfer control within a data processing system provides support for radix 2, 4 and 8 fast Fourier transform (FFT) algorithms through data reordering or bit-reversed addressing across multiple PEs, carried out concurrently with FFT computation on a digital signal processor (DSP) array by a DMA unit. Parallel data distribution and collection through forms of multicast and packet-gather operations are also supported.

Methods and apparatus for providing bit-reversal and multicast functions utilizing DMA controller

Techniques are described for efficient reordering of data and performing data exchanges within a register file or memory, or in general, any device storing data that is accessible through a set of addressable locations. An address translator is placed in the path of all or a selected set of address busses to a storage device to provide a programmable and selectable means of translating the storage device addresses. An effect of this translation is that the data stored in one pattern may be accessed and stored in another pattern or accessed, processed and stored in another pattern. The address translation operation may be carried out in a single cycle, does not involve the physical movement of data in swap operations, allows data to effectively be ordered more efficiently for algorithmic processing and therefore saves power.

Methods and apparatus for address translation functions

Processor pipeline controlling techniques are described which take advantage of the variation in critical path lengths of different instructions to achieve increased performance. By examining a processor's instruction set and execution unit implementation's critical timing paths, instructions are classified into speed classes. Based on these speed classes, one pipeline is presented where hold signals are used to dynamically control the pipeline based on the instruction class in execution. An alternative pipeline supporting multiple classes of instructions is presented where the pipeline clocking is dynamically changed as a result of decoded instruction class signals. A single pass synthesis methodology for multi-class execution stage logic is also described. For dynamic class variable pipeline processors, the mix of instructions can have a great effect on processor performance and power utilization since both can vary by the program mix of instruction classes. Application code can be given new degrees of optimization freedom where instruction class and the mix of instructions can be chosen based on performance and power requirements.

Methods and apparatus for adapting pipeline stage latency based on instruction type

Hardware and software techniques for interrupt detection and response in a scalable pipelined array processor environment are described. Utilizing these techniques, a sequential program execution model with interrupts can be maintained in a highly parallel scalable pipelined array processing containing multiple processing elements and distributed memories and register files. When an interrupt occurs, interface signals are provided to all PEs to support independent interrupt operations in each PE dependent upon the local PE instruction sequence prior to the interrupt. Processing/element exception interrupts are supported and low latency interrupt processing is also provided for embedded systems where real time signal processing is required. Further, a hierarchical interrupt structure is used allowing a generalized debug approach using debut interrupts and a dynamic debut monitor mechanism.

Methods and apparatus for scalable array processor interrupt detection and response

A control processor is used for fetching and distributing single instruction multiple data (SIMD) instructions to a plurality of processing elements (PEs). One of the SIMD instructions is a thread start (Tstart) instruction, which causes the control processor to pause its instruction fetching. A local PE instruction memory (PE Imem) is associated with each PE and contains local PE instructions for execution on the local PE. Local PE Imem fetch, decode, and execute logic are associated with each PE. Instruction path selection logic in each PE is used to select between control processor distributed instructions and local PE instructions fetched from the local PE Imem. Each PE is also initialized to receive control processor distributed instructions. In addition, local hold generation logic is associated with each PE. A PE receiving a Tstart instruction causes the instruction path selection logic to switch to fetch local PE Imem instructions.

Methods and apparatus for independent processor node operations in a SIMD array processor

Details of a highly cost effective and efficient implementation of a manifold array (ManArray) architecture and instruction syntax for use therewith are described herein. Various aspects of this approach include the regularity of the syntax, the relative ease with which the instruction set can be represented in database form, the ready ability with which tools can be created, the ready generation of self-checking codes and parameterized test cases. Parameterizations can be fairly easily mapped and system maintenance is significantly simplified.

Techniques are described for efficient reordering of data and performing data exchanges within a register tile or memory, or in general, any device storing data that is accessible through a set of addressable locations. In one technique, an address translator is placed in the path of all or a selected set of address busses to a storage device to provide a programmable and selectable means of translating the storage device addresses. An effect of this translation is that the data stored in one pattern may be accessed and stored in another pattern or accessed, processed and stored in another pattern. The address translation operation may be carried out in a single cycle, does not involve the physical movement of data in swap operations, allows data to effectively be ordered more efficiently for algorithmic processing and therefore saves power. Address translation functions are shown to be useful for vector operations and a new type of storage unit using built in address translation functions is presented.
