Mobile users frequently want mobile devices as powerful as desk top PCs, but still in a small and light form factor. The level of users' demand is yet too high to satisfy with current technology. Available resources such as CPU, memory, and battery power are still insufficient for current mobile devices. One way to overcome these limitations is to offload(More)
In many computer systems with large data computations, the delay of memory access is one of the major performance bottlenecks. In this paper, we propose an enhanced field remapping scheme for dynamically allocated structures in order to provide better locality than conventional field layouts. Our proposed scheme reduces cache miss rates drastically by(More)
— Mobile consumer devices take increasingly important roles, more closely and personally interacting with users. As users get used to mobile devices, they often want the same level of computing experience as they can have from desktop PCs, but still in small and light form factors. Considering current technology, we find the limitations of the processor and(More)
Aggressive embedded processors are often equipped with general purpose cores and special purpose acceleration logics. In our paper, we consider a reconfigurable processor that consists of very long instruction word (VLIW) cores and coarse grained reconfigurable arrays (CGRAs). CGRAs are particularly used to enhance the performance by exploiting loop(More)
Recent electronic devices are equipped with processors extended with multicore accelerators to take advantage of the powerful performance from acceleration co-processors. Applications on such high-end electronic products require capability to run graphic-rich applications. Scalable acceleration co-processors are frequently designed as multicores with(More)
In imperative synchronous languages, a statement is called schizophrenic if it is executed more than once in a single clock. When a schizophrenic statement is translated into a circuit, the circuit can behave abnormally because of the multiple executions. To solve the problems caused by schizophrenic statements, compilers duplicate the statements to avoid(More)
