An apparatus and method for performing SIMD multiply-accumulate operations includes SIMD data processing circuitry responsive to control signals to perform data processing operations in parallel on multiple data elements. Instruction decoder circuitry is coupled to the SIMD data processing circuitry and is responsive to program instructions to generate the required control signals. The instruction decoder circuitry is responsive to a single instruction (referred to herein as a repeating multiply-accumulate instruction) having as input operands a first vector of input data elements, a second vector of coefficient data elements, and a scalar value indicative of a plurality of iterations required, to generate control signals to control the SIMD processing circuitry. In response to those control signals, the SIMD data processing circuitry performs the plurality of iterations of a multiply-accumulate process, each iteration involving performance of N multiply-accumulate operations in parallel in order to produce N multiply-accumulate data elements. For each iteration, the SIMD data processing circuitry determines N input data elements from said first vector and a single coefficient data element from the second vector to be multiplied with each of the N input data elements. The N multiply-accumulate data elements produced in a final iteration of the multiply-accumulate process are then used to produce N multiply-accumulate results. This mechanism provides a particularly energy efficient mechanism for performing SIMD multiply-accumulate operations, as for example are required for FIR filter processes.

A data processing apparatus is provided wherein processing circuitry executes multiple program threads including at least one high priority thread and at least one lower priority thread. Instructions required by the threads are retrieved from a cache memory hierarchy comprising multiple cache levels. The cache memory hierarchy includes a bypass path for omitting a predetermined level of the cache memory hierarchy when performing a lookup procedure for a required instruction and for bypassing said predetermined level of the cache memory hierarchy when returning said required instruction to said processing circuitry. The bypass path is used by default when the requested instruction is for a lower priority thread.

Structures based upon periodic cellular materials that provide a potential for defeating combinations of both air blast loading and ballistic attack either sequentially or simultaneously, or combination of both. The cellular structures may also be configured to meet the stiffness and strength support requirements of particular vehicle or other applications, systems or structures. The armor is therefore potentially able to support normal service loads and defeat blast and ballistic threats when necessary. The structure provides for using efficient load support capabilities of the material (without a high armor protection level) in low threat conditions, as well as the ability to modify the system to increase its level protection to a desired or required level. This would reduce the weight of the protection system in normal (low threat) conditions which reduces vehicle wear and tear, as well as cost savings in fabrication of applicable structures or systems.

An optimal thermal seawater desalination process is disclosed, which combines two or more substantially different water pretreatment processes in a unique manner and in a special configuration, hereto unknown to prior desalination arts, to produce a high yield of high quality fresh water, including potable water. In this process a two stage NF membrane pretreatment unit (NF2) with an energy recovery turbo charger (TC) device in between the stages or equipped with an energy recovery pressure exchanger (PX) is synergistically combined with at least one thermal desalination unit to form a dual hybrid of NF2-Thermal (FIG. 4 ), or alternatively the two stage NF2 unit is synergistically combined with a two stage SWRO unit (SWRO2) with an energy recovery TC in between the stages or combined with one stage SWRO (SWRO1) equipped with an energy recovery TC or PX system and the reject from the SWRO2 or SWRO1 unit is made make-up to a thermal unit to form a tri-hybrid of NF2-SWRO2 reject-Thermal (FIG. 5 ). In both the cases of di- or trihybrids the thermal unit is equivalent to a multistage flash distillation (MSFD) or multieffect distillation (MED) or vapor compression distillation (VCD) or thermal reheat (RH) evaporator. Typically a process of this invention using the two stage NF2 initial pretreatment step will perform a semi-desalination step by reducing feed TDS by about 35 to 50%, but most important, especially to the thermal seawater desalination process, it removes the water recovery limiting, scale forming hardness ions of Ca++ and Mg++ by better than 80% and their covalent anions of sulfate to better than 95% and bicarbonate to about 65%. The removal of scale forming hardness ions, especially SO4=, and bicarbonates allowed for the operation of thermal unit in the above hybrids at top brine temperature (TBT) much greater than its present TBT limit by the singular conventional process of 120° C. for MSFD and operation of MED or VCD or RH unit at TBT much higher than their present TBT limit of 65-70° C., with many advantages gained by this process over prior art sweater desalination processes. The process of this invention exceeds all prior thermal seawater desalination arts in efficiency, including water yield, product water recovery ratio and unit water cost as well as in energy consumption per unit product which is equivalent or less than other efficient prior art seawater thermal desalination processes. By this process, an NF product recovery ratio of 75 and 80% or better is achieved from the high salinity Gulf sea (TDS≈45,000 ppm) and about an equal product recovery ratio is also obtained from the SWRO or thermal unit when it is operated on NF product for a total water recovery ratio in excess of 52% for seawater

IEEE 802.11 power management scheme for an ad hoc network is based on the Carrier Sense Multiple Access with Collision Avoidance (CSMA / CA) access procedure to transmit / receive their data frames. CSMA / CA may waste the scarce energy and bandwidth due to frame collisions and lengthen the frame delay due to waiting backoff time. In addition, IEEE 802.11 power management scheme does not specify how to tune the ATIM window size in a beacon interval. However, the ATIM window size affects the power consumption and throughput of a network considerably. The fixed ATIM window size cannot always accommodate the various traffic conditions. To conquer these problems and to improve the performance of networks, we propose a energy efficient MAC protocol for IEEE 802.11 networks by scheduling transmission after the ATIM window and adjusting the ATIM window dynamically to adapt to the traffic status.
