摘要： The first, second, and third operating units 441 to 443 each perform a predetermined operation according to an instruction before a point of time partway through a clock cycle. When having performed a comparison operation, each operating unit outputs a result value to the condition flag operating unit 51. The condition flag operating unit 51 calculates a new condition flag value by performing a logical operation on either (a) a value that has been read from the condition flag register 46 and the result value or (b) the result values themselves. The condition flag operating unit 51 outputs, before the clock cycle ends, the new condition flag value to one of the first, second, and third gates 451 to 453 that is related to a conditional instruction so as to control nullification of the conditional new condition flag value.

摘要： Disclosed is a compiler apparatus for generating an instruction code composed of instruction sets each including an instruction that designates an m-bit immediate value indicating a location of a data item in a memory area. The compiler apparatus sequentially selects, based on one data attribute, a data item from a group X composed of a plurality of data items; and judges, each time a data item is selected, whether the selected data item is allocatable to an n-byte memory area (n≦2m). When the judgment is negative, the compiler apparatus specifies, based on a different data attribute, a data item out of all the selected data items and excludes the specified data item from the group X, and repeats the selection until all the data items remaining in the group X after excluding specified data items are judged to be allocatable to the memory area.

摘要： A compiling unit (110) generates indefinite branch information showing that an instruction set to be selected is indefinite, instead of generating a branch instruction. A linking unit (130) generates an appropriate direct addressing branch instruction by judging whether an instruction set used at a branch source and an instruction set used at a branch destination are the same. Also, one reference instruction set is determined. The compiling unit (110) adds a mode adjusting instruction that belongs to the reference instruction set and that is for causing a branch to an instruction placed at a branch destination and for selecting the instruction set that is originally to be selected. The mode adjusting instruction provides an alternative branch destination corresponding to an original branch destination, and the compiling unit (110) generates an indirect addressing branch instruction for causing a branch to the alternative branch destination and for selecting the reference instruction set.

摘要： In order to overcome the problem that conditionally executed instructions are executed as no-operation instructions if their condition is not fulfilled, leading to poor utilization efficiency of the hardware and lowering the effective performance, the processor decodes a number of instructions that is greater than the number of provided computing units and judges their execution conditions with an instruction issue control portion before the execution stage, Instructions for which the condition is false are invalidated, and subsequent valid instructions are assigned so that the computing units (hardware) is used efficiently. A compiler performs scheduling such that the number of instructions whose execution condition is true does not exceed the upper limit of the degree of parallelism of the hardware. The number of instructions arranged in parallel at each cycle may exceed the degree of parallelism of the hardware.

摘要： A compiler device includes a conditional-executable-instruction generation unit and a branch instruction insertion unit. The conditional-executable-instruction generation unit generates a conditional executable instruction that is executed when a condition that the conditional executable instruction refers to is satisfied. In the case where there is a section containing a non-executive condition under which no instruction is executed in one cycle or a plurality of cycles in series, the branch instruction insertion unit inserts a conditional branch instruction that refers to the non-executive condition and instructs to branch to a cycle immediately after a last cycle of the section, to after an instruction of a cycle immediately before a start of the section. Thus, a compiler device employing conditional executable instructions is provided that is capable of generating an assembler code that does not degrade the performance when the instructions are executed, even if a source program includes a branch instruction that causes a then part and an else part to be executed through unbalanced numbers of cycles, respectively.

摘要： When a branch instruction is decoded by the instruction decoders 409a-409c, the upper 29 bits of the PC relative value included in the branch instruction are sent to the upper PC calculator 411 and the lower 3 bits are sent to the lower PC calculator 405. The lower PC calculator 405 adds the lower 3 bits of the PC relative value and the lower 3 bits of the present lower PC 404 and sends the result to the lower PC 404 as the updated lower PC. The upper PC calculator 411 adds the upper 29 bits of the PC relative value, the upper 29 bits of the present upper PC 403, and a carry that may be received from the lower PC calculator 405, and sends the result to the upper PC 403 as the updated upper PC.
