摘要:
Provided is an apparatus and method for generating code overlay capable of minimizing the number of memory copies. A static temporal relationship graph (STRG) is generated in which each of functions of a program corresponds to a node of the STRG and a conflict miss value corresponds to an edge of the STRG. The conflict miss value is the maximum number of possible conflict misses between functions. Overlay is generated by selecting at least one function from the STRG, calculating an allocation cost for each region of a memory to be given when the at least one selected function is allocated, and allocating the at least one selected function to a region that has the smallest allocation cost.
摘要:
A multiprocessor using a shared virtual memory (SVM) is provided. The multiprocessor includes a plurality of processing cores and a memory manager configured to transform a virtual address into a physical address to allow a processing core to access a memory region corresponding to the physical address.

An apparatus for processing an invalid operation in a prologue and/or an epilogue of a loop includes a register file including a first region for storing a data validity value indicating whether data is valid or invalid, and a second region for storing the data; and a functional unit configured to determine whether an operation is valid or invalid based on a value of a first region of each of one or more input sources received from the register file, and output a destination including a value based on the value of the first region of each of the input sources
摘要:
Provided is a reconfigurable processor that may process a first type of operation in first mode using a first group of functional units, and process a second type of operation in second mode using a second group of functional units. The reconfigurable processor may selectively supply power to either the first group or the second group, in response to a mode-switch signal or a mode-switch instruction.
摘要:
Provided is a reconfigurable processor capable of reducing the routing processing time of routing nodes by driving the routing nodes at a greater frequency than a driving frequency of the processing elements. The reconfigurable processor includes one or more processing elements configured to be driven at a first driving frequency, and one or more routing nodes configured to be provided on paths that are formed between the processing elements, and to be driven at a second driving frequency that is greater than the first driving frequency.
摘要:
A scheduler of a reconfigurable array, a method of scheduling commands, and a computing apparatus are provided. To perform a loop operation in a reconfigurable array, a recurrence node, a producer node, and a predecessor node are detected from a data flow graph of the loop operation such that resources are assigned to such nodes so as to increase the loop operating speed. Also, a dedicated path having a fixed delay may be added to the assigned resources.
