摘要： Provided is a processor and method of performing speculative load instructions of the processor in which a load instruction is performed only in the case where the load instruction substantially accesses a memory. A load instruction for canceling operations is performed in other cases except the above case, so that problems occurring by accessing an input/output (I/O) mapped memory area and the like at the time of performing speculative load instructions can be prevented using only a software-like method, thereby improving the performance of a processor.

摘要： A loop coalescing method and a loop coalescing device are disclosed. The loop coalescing method comprises removing an inner-most loop from among nested loops, so that an outer operation provided outside of the inner-most loop is performed when a condition of a conditional statement is satisfied, generating a guard code by applying an if-conversion method to the conditional statement, and converting a guard by using an instruction calculating the guard of the guard code, the instruction calculating the guard using a register where information related to a period of time corresponding to the number of iterations of the inner-most loop is stored.

摘要： Provided are a loop accelerator and a data processing system having the loop accelerator. The data processing system includes a loop accelerator which executes a loop part of a program, a processor core which processes a remaining part of the program except the loop part, and a central register file which transmits data between the processor core and the loop accelerator. The loop accelerator includes a plurality of processing elements (PEs) each of which performs an operation on each word to execute the program, a configuration memory which stores configuration bits indicating operations, states, etc. of the PEs, and a plurality of context memories, installed in a column or row direction of the PEs, which transmit the configuration bits along a direction toward which the PEs are arrayed. Thus, a connection structure between the configuration memory and the PEs can be simplified to easily modify a structure of the loop accelerator so as to extend the loop accelerator.
