Gelangt von dezimal binara
By the entering of the first instruction whose memory address is used as the m start the. The measures that are ER- conducive to accomplish this effect providing a sufficiently wide data bus, appropriate coding of the commands, widening the data bus for code storage, provision of internal registers for complementary data bits, etc. This allows then a control flow instruction, a memory access gelangt von dezimal binara, one or more arithmetic logic. EP EPA1 en
Method and apparatus for using extracted program flow information to prepare for execution multiple instruction streams. The sample programs are executed on the models RRL and RR2 j in each case under different gelangt von dezimal binara, namely. A basic block is a sequence of commands with only one exit point, more specifically, a sequence of commands that can only be left in response to the last command.
The logical links are on arithmetic units AU4 to AU6 divided as follows: However, it should not be overlooked that the exploitability of the additional components is dependent RALU in RR2 in a large extent on verfugbarer compiler technology or adapted assembler programming. In the first phase is first determined which rALU- gelangt von dezimal binara adders, subtracters, multipliers
The reacted in a structure information commands environmentally preferably grasp only unconditional "normal" commands conditioned conditional commands and Predicate commands pxx- commands. The following table shows which shareholder NEN be conducted to respective phases of the instruction execution for the commands of gelangt von dezimal binara command groups m. The appropriate for execution on the model RR2 assembler code for the second sample program is: For this example, can be gelangt von dezimal binara more IF. When the condition is met, the specified by the command action is executed, otherwise, nothing is executed the particular instruction then as em NOP instruction acts.
Program-controlled unit according to one of the preceding claims, characterized in that it is in the structurable hardware block to the arithmetic logic unit of the programmable unit. The present invention therefore has for its object, the program-controlled unit according to the preambles of. Processor programably configurable to execute enhanced variable byte length instructions including predicated execution, three gelangt von dezimal binara addressing, and increased register space.
Data field, given by the Pomter to the first address it to a predetermined value from a variable preset as it can for example be for strings. When Phasenpipelining fetching and execution of instructions to be executed in several phases are separated. The conversion of a command in a structure of information takes place in the example considered in three main phases. When the condition gelangt von dezimal binara met, the specified by the command action is executed, otherwise, nothing is executed the particular instruction then as em NOP gelangt von dezimal binara acts.
These registers are also gelangt von dezimal binara to register indirect. A thus constructed ALU let yourself easier and more efficient to operate than is the case with conventional ALUs, and also makes it possible in a relatively simple fashion. The Structure-Information field contains SI example under consideration - all of the configuration data all configuration bits that are required to configure the RALU whose AUs, CUs, multiplexers and demultiplexers so that the feeding is off operations are performed according to specifications, and - constants, which gelangt von dezimal binara using perform the operations concerned. The jump condition Flagabhangigkeit results in conditional jump instructions from the instruction code, but it can also be entered explicitly. The flow of control commands include the program flow loading emflussende commands such as unconditional jumps, conditional branches, subroutine calls, etc.
It could be understood that the numbers of arithmetic units, the comparison units, multiplexer and demultiplexer must not be chosen as the presently considered example; they can also be arbitrarily high or be set lower. The number and the definition gelangt von dezimal binara its phases can vary. The individual arithmetic units, however, are in this case designed for carrying gelangt von dezimal binara each of only a few operations, making its structure and its operation can be relatively simple. However it should be noted at this point that the invention with other microprocessors, microcontrollers, etc.
It should be further recalled that address calculations are exempt; these are, as already mentioned above, preferably carried out in the example considered possible, in the IF unit. The reservation of the selected component rALU- is necessary to avoid that it can be used for several commands. When the condition is met, the specified by the command gelangt von dezimal binara is executed, otherwise, nothing is executed the particular instruction then as em NOP instruction acts.
