In an effort to make processors more power efficient scratch pad memory (SPM) have been proposed instead of caches, which can consume majority of processor power. However, application mapping on SPMs remain a challenge. We propose a dynamic SPM management scheme for program stack data for processor power reduction. As opposed to previous efforts, our(More)
Many programmable embedded systems feature low power processorscoupled with fast compiler controlled on-chip scratchpad memories (SPMs) toreduce their energy consumption. SPMs are more efficient than caches in termsof energy consumption, performance, area and timing predictability. However,unlike caches SPMs need explicit management by software, the quality(More)
A dynamic scratch pad memory (SPM) management scheme for program stack data with the objective of processor power reduction is presented. Basic technique does not need the SPM size at compile time, does not mandate any hardware changes, does not need profile information, and seamlessly integrates support for recursive functions. Stack frames are managed(More)
The current literature on femoroacetabular impingement (FAI) is focused on acetabular orientation and femoral head asphericity, with little emphasis on the effect of version of the femoral neck. A biomechanical model was developed to determine the causative effect, if any, of femoral retroversion on hip contact stress and, if present, delineate the type of(More)
Advances in the imaging techniques of the heart have fueled the interest in understanding of right heart pathology. Recently, speckle tracking echocardiography has shown to aid in understanding various right heart diseases and better management. Its role is well established in diagnosing right heart failure, pulmonary artery hypertension, arrhythmogenic(More)
BACKGROUND Femoroacetabular impingement has been postulated as the important cause of primary osteoarthritis in non dysplastic hips. We postulated that the rarity of primary osteoarthritis of hip in Indian population could be attributable to morphological differences, specifically to a lower prevalence of abnormal head-neck morphology. We conducted an(More)
Developmental abnormalities of the thyroid gland are very rare. The most common abnormalities include ectopic thyroid tissues that are commonly seen in lingual or sublingual location, agenesis, and hemiagenesis of the thyroid gland. These developmental defects may or may not be associated with thyroid dysfunction. Our case is an 18-year-old male who(More)
Attainment of a neutral mechanical axis is one of the primary goals in total knee arthroplasty (TKA). The accuracy of the procedure is evaluated by measuring the hip-knee-ankle angle (HKAA) on long leg radiographs. Rotation of the lower limb and knee flexion could possibly affect the HKAA measured on plain radiographs. In this study, a TKA was performed on(More)
BACKGROUND iatrogenic devascularization of the femoral head is as an area of concern following hip resurfacing arthroplasty, with probable implications on short-term failure and long-term survival of the implant. MATERIALS AND METHODS we assessed the vascularity of 25 resurfaced femoral heads in 20 patients by comparison with preoperative and(More)
By 2011, the Integrated Circuit(IC) feature sizes are expected to be reduced to 22nm from present day 45nm, and the soft error rate will increase by 3 to 4 orders of magnitude (from one per year to one per hour). International Technology Roadmap for Semiconduc-tors(ITRS) indicates that techniques for mitigating soft errors are crucial for future generations(More)
