Design of Low-Power Coarse-Grained Reconfigurable by Yoonjin Kim

By Yoonjin Kim

Coarse-grained reconfigurable structure (CGRA) has emerged as an answer for versatile, application-specific optimization of embedded platforms. supporting you realize the problems eager about designing and developing embedded structures, layout of Low-Power Coarse-Grained Reconfigurable Architectures deals new frameworks for optimizing the structure of parts in embedded structures which will lessen quarter and retailer energy. genuine program benchmarks and gate-level simulations substantiate those frameworks. the 1st 1/2 the e-book explains tips on how to lessen strength within the configuration cache. The authors current a low-power reconfiguration process according to reusable context pipelining that merges the idea that of context reuse into context pipelining. additionally they suggest dynamic context compression in a position to assisting required bits of the context phrases set to permit and the redundant bits set to disable. additionally, they speak about dynamic context administration for lowering energy intake within the configuration cache by way of controlling a read/write operation of the redundant context phrases. targeting the layout of an economical processing point array to lessen region and tool intake, the second one half the textual content offers a cheap array textile that uniquely rearranges processing components and their interconnection designs. The publication additionally describes hierarchical reconfigurable computing arrays together with reconfigurable computing blocks with sorts of verbal exchange constitution. the 2 computing blocks proportion serious assets, supplying a good conversation interface among them and lowering the final region. the ultimate bankruptcy takes an built-in method of optimization that attracts at the layout schemes offered in past chapters. utilizing a case research, the authors reveal the synergy impact of mixing a number of layout schemes.

However, each nano processor does not directly control the instructions it executes. Every cycle the nano processor receives a PC value, “nano PC”, from the global control unit. All nano processors use the same nano PC and execute the instructions indexed by the nano PC in their nano instruction RAM. 9 shows the architecture of the nano processor. 8: Block diagram of REMARC. (From T. Miyamori and K. ” In Proceedings of IEEE Symposium on FPGAs for Custom Computing Machines, c 1998 IEEE. 9: Block diagram of REMARC.

The chip has 132 pins, which includes a 72-pin data interface, 5-bit test interface and 53 pins for power and ground. 8V supplies for the I/Os and core, respectively. The core area is divided into two areas: (1) the fabric, and (2) the virtualization and interface logic.

Because the width of the HBUS and the VBUS is 32 bits, data on the HBUS or the VBUS are stored into a DIR register pair, DIR0 and DIR1, or DIR2 © 2011 by Taylor and Francis Group, LLC Trends in CGRA 17 and DIR3. Using the DIR registers, data can be transferred between nano processors during ALU operations. It takes a half cycle to transfer data using the VBUSs or HBUSs. It should not be a critical path of the design. Other operations, except for data inputs from nearest neighbors, are done within the nano processor.
