Definitions
- the invention relates to a method for memory configuration with I / O support, this configuration realizing the storage of data of a processor unit in a processor memory and their input / output via an i / O unit.
- the invention further relates to an arrangement for performing the above-mentioned method according to the preamble of claim 4.
- DMA direct memory access
- Functional units for the functional unit operating under particularly time-critical conditions for example a processor Unit to ensure the appropriate priority when accessing data.
- Another disadvantage is that with a DMA request there is always a certain time delay before the required memory access is made available.
- the invention is based on the object of a time-critical functional unit, e.g. a processor unit to enable direct memory access, which is largely available without delay, while avoiding data collisions that occur when operating with other functional units, e.g. an l / ⁇ functional unit with direct memory access can occur.
- a time-critical functional unit e.g. a processor unit to enable direct memory access, which is largely available without delay, while avoiding data collisions that occur when operating with other functional units, e.g. an l / ⁇ functional unit with direct memory access can occur.
- the inventive solution of the task provides that an input memory area is agreed in the processor memory, into which the I / ⁇ unit can only write and from which the processor unit can only read and that an output Memory area is agreed from which the I / O unit can only read and into which the processor unit can only write.
- a direct assignment of the memory area to the functional units guarantees a delay-free READ or WRITE memory access. Furthermore, the basic agreement on the possible READ / WRITE accesses for each memory area prevents data collisions by defining the course of the bidirectional data paths of the I / O unit and processor unit.
- An important variant of the procedural solution of the task provides that the data access when reading and writing in or out of the input memory area and in or from the output memory area of the processor memory by means of the I / O unit and by means of the processor unit. This prevents the CPU from being used for address management tasks.
- a special variant of the procedural solution of the task provides that the data access during reading and writing into or from the input memory area and into or from the output memory area of the processor memory by means of the I / O unit and can be realized by means of the processor unit in each case in a block with a block length that corresponds to the line length of the processor memory organization.
- This solution is advantageously used if the functional units are accessed frequently or exclusively with a certain block length. In this way, the number of command instructions that must be transmitted by the CPU is reduced.
- the inventive solution of the task provides that a data port of the processor unit is connected to a first data port of the processor memory and that a data port of the I / O unit is connected to a second data port of the processor memory.
- a corresponding multi-data port of the processor memory is also realized and this multi-data port with the corresponding data ports of the functional units communicates.
- Another arrangement-side solution according to the invention of The task provides that an i / o address generator is arranged in the i / o unit and a processor address generator is arranged in the processor unit.
- This enables the above-mentioned functional units to address data access independently.
- the processor memory is also equipped with a multi-address port and that an address port of the processor unit is connected to a first address port of the processor memory and that an address port of the I / ⁇ unit is connected to a second Address port of the processor memory is connected.
- the READ / WRITE control is also guaranteed by the functional units, in that a multi-READ / WRITE port is also implemented on the processor memory and a READ / WRITE port of the i / O unit with a first READ / WRITE Processor memory port is switched that a READ / WRITE port of the processor unit is switched with a second READ / WRITE port of the processor memory.
- a favorable arrangement-side solution of the task according to the invention provides that a block length port is arranged on the I / O address generator and on the processor address generator. This creates an input option for the block lengths of the data accesses to be processed by the l / ⁇ unit and the processor unit.
- An advantageous solution according to the invention on the arrangement side provides that a FIFO memory is arranged in the processor memory. Since the data path of the processor unit leads directly to the processor memory, a FIFO memory that acts as an intermediate buffer is also sor memory arranged.
- the associated drawing figure shows a schematic representation of the processor memory 1 with the assigned processor functional unit 2 and the associated I / ⁇ functional unit. Furthermore, it can be seen in the drawing figure that an I / O functional unit address port 11 is arranged in the I / O functional unit 3, which is connected to the second processor memory address port 13, which in turn is arranged on the processor memory 1 is.
- the I / O functional unit address port 11 is controlled by the i / O address generator 15, which is given the block length by the i / O block length port 17 when it is initialized, i. the number of consecutive data in the data block in the data access is communicated.
- the I / ⁇ READ / WRITE port 19 arranged on it outputs the WRITE state to the second processor memory READ / WRITE port 21 connected to it, which is arranged on the processor memory 1.
- the addresses of the data blocks to be transferred from the I / O function unit 3 to the processor memory 1 are in the agreed input memory area 4 of the processor memory 1. They are sent from the I / O function unit address port 11 to the one connected to it second processor memory address port 13, which is arranged on the processor memory 1, transmitted.
- the data associated with these addresses arrive from the I / O functional unit data port 7, which is arranged on the I / O functional unit 3, via the second processor connected to it and arranged on the processor memory 1 -Spei- cher data port 9 and via the second FIFO (first-in-first-out) memory 23, which is also arranged on the processor memory 1, into the input memory area 4 of the processor memory 1.
- the data are available for further processing with a READ data access in the processor functional unit 2 ready.
- the READ data access of the processor functional unit 2 can only take place for the agreed address area of the input memory area 4 and the required addresses are provided by the processor address generator 14, which is arranged on the processor functional unit and which is also arranged by the processor Block length port 16 has been initialized. These addresses are output to the processor functional unit address port 10, which is arranged on the processor functional unit 2 and which is connected to the first processor memory address port 12 arranged on the processor memory 1, and thus control the addressed memory cells of the Input memory area 4.
- the processor READ / WRITE port 18 arranged on it outputs the READ state to the first processor memory READ / WRITE port 20 connected to it , which is arranged on the processor memory 1.
- a prerequisite for successful READ data access by the processor functional unit is that the data associated with the addressed addresses is via the first FIFO memory 22 arranged on the processor memory 1 and the first processor memory 1 also arranged on the processor memory 1.
- Data port 8 and the processor functional unit data port 6 connected to it, which is arranged on the processor functional unit 2, are provided for further processing in the processor functional unit 2.
