It is well known that innermost loop optimizations have a big effect on the total execution time. Although CGRAs is widely used for this type of optimizations, their usage at run-time has been limited due to the overheads introduced by application analysis, code transformation, and reconfiguration. These steps are normally performed during compile time. In this work, we present the first dynamic translation technique for the modulo scheduling approach that can convert binary code on-the-fly to run on a CGRA. The proposed mechanism ensures software compatibility as it supports different source ISAs. As proof of concept of scaling, a change in the memory bandwidth has been evaluated (from one memory access per cycle to two memory accesses per cycle). Moreover, a comparison to the state-of-the-art static compiler-based approaches for inner loop accelerators has been done by using CGRA and VLIW as target architectures. Additionally, to measure area and performance, the proposed CGRA was prototyped on a FPGA. The area comparisons show that crossbar CGRA (with 16 processing elements) is 1.9x larger than the VLIW 4-issue and 1.3x smaller than a VLIW 8-issue softcore processor, respectively. In addition, it reaches an overall speedup factor of 2.17x and 2.0x in comparison to the 4 and 8-issue, respectively. Our results also demonstrate that the runtime algorithm can reach a near-optimal ILP rate, better than an off-line compiler approach for an n-issue VLIW processor.
International Journal of Open Access Otolaryngology Open Access Review ArticleThe evolution of the CI has been notable in the development of the external component -microphone, speech processor, transmitter -with a constant evolution over the years. This same evolution allows us to have speech processors miniaturized and increasingly effective in auditory processing. The inner component is formed by the receiver and the electrode array. The receptor has remained similar over the years, but the electrode array has evolved considerably and we now have several types of electrode bundles available for cochlear implantation [2]. This evolution allowed to extend the surgical indication to patients with anatomical alterations of the cochlea and other associated clinical conditions that previously contraindicated the surgery. Cochlear implantation has thus become the most widely used and consensual therapeutic method in the treatment of severe to profound neurosensory deafness.The widening of clinical indications for cochlear implantation increased not only the number of patients implanted but also the number of new difficulties and complications associated with implantation [3,4].One commonly used division to characterize complications is the separation of major and minor complications. In the group of major complications we have meningitis, immediate postoperative facial paralysis, implant failure, flap dehiscence, surgical removal necessity. In the minor complications we have wound infection, vestibular symptoms, non-immediate facial paralysis and non-auditory electrical stimulation [5,6]. ObjectivesTo evaluate the different causes that led to the need to disconnect electrodes in the patients implanted in the Functional Unit of Cochlear Implants and to verify if there were alterations in the auditory performance comparing with the patients in whom it was not necessary to disconnect electrodes. MethodsReview of all cases of adult patients implanted in the Unit for Cochlear Implantation in Coimbra Hospital and University Center Abstract Introduction: With the evolution of cochlear implantation techniques and the results achieved, the implantion indications increased. The increase of implanted patients also increases the possibility of complications related to surgical technique and the proper performance of the implanted material. The solution regarding some of these complications may be to switch off electrodes.
Background: Using the telephone for everyday communication and social interaction allows the profoundly deaf patient who uses a cochlear implant to increase their independence and self-esteem. Being able to use the telephone presupposes the ability to perceive speech without the aid of lipreading or any other visual cue.Objective: This paper aims to evaluate speech perception performance through the telephone in adult users of cochlear implants.Study sample: 200 adult patients who had used a cochlear implant for a minimum of 1 year were evaluated with speech perception tests (words and sentences) in free-field and through the telephone. They were divided into two groups: group I, composed of individuals who used the telephone in everyday life, and group II, individuals who did not use it. Results:The results showed statistically significant differences in free-field tonal and vocal thresholds between both groups, with better performance from group I. When the speech perception test results in free-field and through the telephone were compared, for both groups the performance was better in free-field. Conclusions:The results showed a statistically significant difference between the two groups, with better performance from group I in all tests.
