Dynamically Reconfigurable Processor (DRP) developed by NEC Electronics is a coarse grain re-configurable processor that selects a data path from the on-chip repository of sixteen circuit configurations , or contexts, to implement different logic on one single DRP chip. Several stream applications have been implemented on the DRP-1, the first prototype(More)
Virtual hardware is difficult to be implemented even on recent dynamic reconfigurable processors when the loop body of the target application cannot be stored in the set of quickly switch-able contexts. Here, techniques for such tough cases are proposed. Differential configuration which changes only different part of similar context can drastically reduce(More)
JPEG2000 is a new standard that was developed to take over the widely used JPEG standard. In JPEG2000, the use of wavelet transform and EBCOT greatly improves the quality of the image and the compression ratio. They do, however, take up a lot of processing time. We therefore implemented the processing intensive tasks, namely the reversible discrete wavelet(More)
— For a class of networked systems consisting of heterogeneous multi-dimensional subsystems, this paper proposes a novel knockout based method to identify the strength of the interaction between specified two nodes based on the input-output data of the networked systems, under the condition that the dynamics of the corresponding nodes is known. Our method(More)
Multicontext reconfigurable processors can switch its configuration in a single clock cycle by providing a context memory in each of the processing elements. Although these processors have proven to be powerful in many applications, the number of contexts is often not enough. The context translation table which translates the global instruction pointer, or(More)
BACKGROUND Vesicourethral anastomotic stricture (VAS) is a rare but serious complication following radical prostatectomy (RP), and various types of managements for VAS have been proposed. We investigated the efficacy of transurethral balloon dilation in the management of VAS after RP. METHODS A total of 128 consecutive patients underwent open RP at our(More)
