In the embedded domain, memory usage and energy consumption are critical constraints. Embedded processors such as the ARM and MIPS provide a 16-bit instruction set (called Thumb in the case of the ARM cpu family) in addition to the 32-bit instruction set to address these concerns. Using 16-bit instructions one can achieve code size reduction and I-cache energy savings at the cost of performance...

This paper presents a new highly-parallel DSP architecture based on a short-vector memory system developed at Analog Devices, Inc. This DSP incorporates for the first time in an embedded processor a number of techniques found in generalpurpose computing, such as branch prediction, deep and fullyinterlocked pipeline, and SIMD instruction execution. By means of its short-vector high-bandwidth mem...

The eeective bandwidth of a bus and external communication ports can be increased by using a variant of data compression techniques that compacts words instead of data streams. The compaction is performed by caching the high order bits into a table and sending the index into the table along with the low order bits. A coherent table at the receiving end expands the word into it original form. Co...

We present several integral attacks on MISTY1 using the FO Relation, which is derived from Sakurai-Zheng Property used in previous attacks. The FO Relation is a more precise form of the Sakurai-Zheng Property such that the functions in the FO Relation depend on 16-bit inputs instead of 32-bit inputs used in previous attacks, and that the functions do not change for different keys while previous...

this study aimed at examining the effects of iranian efl learners’ anxiety, ambiguity tolerance, and gender on their preferences for corrective feedback (cf, henceforth). the effects were sought with regard to the necessity, frequency, and timing of cf, types of errors that need to be treated, types of cf, and choice of correctors. seventy-five iranian efl students, twenty-eight males and forty...

In this paper, we propose the first ARIA block cipher on both MSP430 and Advanced RISC Machines (ARM) microcontrollers. To achieve optimized implementation target embedded processors, core operations of ARIA, such as substitute diffusion layers, are carefully re-designed for (Texas Instruments, Dallas, TX, USA) ARM Cortex-M3 microcontrollers (STMicroelectronics, Geneva, Switzerland). particular...
