Abstract

PURPOSE:To reduce the size of an arithmetic device which is controlled by one microprogram and shorten a processing time by parallel of processing by performing one operation partially by plural microprograms. CONSTITUTION:The sart of an operation is indicated to microprogram controllers 1 and 6 at the same time. The microprogram controller 1 while controlling a program sequence by itself indicates an arithmetic device 3 to read data out of a register group and store it memory. The microprogram controller 6 while controlling the program sequence by itself indicates an arithmetic device 8 to read memory for old time control information on a task and a timer and generate and store new time control information on the task in the memory. Consequently, the operation is carried out by performing said processes in parallel.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of the Invention] The present invention relates to a microprogram control system having a plurality of microprogram control devices.

[Prior art]

In recent years in the field of information processing equipment, arithmetic units have become larger due to demands for improved performance, and controlling them with a single microprogram is difficult due to the physical location of the control signal wiring. This will increase the control signal propagation time, so
Machine cycle time has become long.1 Furthermore, in the field of information processing equipment, there is a great demand for improved functionality, and the operations that must be executed in one operation are becoming more complex. Processing using a program increases the number of processing steps of the microprogram due to conditional branching, etc., resulting in a decrease in performance.

[Purpose of the invention]

The purpose of the present invention is 1. By dividing and executing one operation by multiple microprograms, the arithmetic unit controlled by one microprogram can be made smaller, the physical distance between them can be shortened, and the processing An object of the present invention is to provide a microprogram control system in which processing time is shortened by parallel execution of .

[School of invention]

A microprogram control system according to the present invention includes a plurality of microprogram control devices capable of independently controlling each microinstruction sequence, and a plurality of operations provided correspondingly to these devices and controlled by the corresponding microprograms. and a configuration for starting each microprogram control device at the same time so that each performance and device can operate simultaneously, and controlling the activated microprogram control devices so that they operate synchronously. It has become.

[Example of invention]

Hereinafter, the features of the present invention will be explained in detail with reference to the drawings.

The figure is a block diagram showing one embodiment of the present invention. In this figure, a microprogram control device @1 sends microinstructions read from a control memory (not shown) in the device 1 via a control line 2. The data is then sent to the arithmetic device 3 and the device 3 is controlled. Arithmetic device 3 has register group 4 and memory 5
The microprogram control device 6 is connected to the control line 7 and executes the operation instructed by the microprogram control device 1.
The performance circuit 8 is controlled via the control circuit 8. Arithmetic circuit 8 is memory 5
and timer 9, and executes operations instructed by microprogram control device 6. The microprogram control device 6 receives a synchronization signal from the microprogram control device 1 via a signal line 10, and operates in synchronization with the microprogram control device 1.

Here, let's take as an example a case where the storage of registers in memory that occurs when switching tasks, etc., and the generation of time management information for managing task processing time, etc. are defined to be executed as one operation unit. Then, this operation can be recognized by being broken down into the following six operations at the microprogram level. That is, α) Read the register group 2) Store the read register group in the memory (3) Read the old riJI management information of the task from the memory
Output 4) Read out the timer 5) Generate time-out management information for the task (6) Store time-out management information in memo ν In conventional information processing devices, the above operations are (1) to (6). It was executed in the following order. However, since the operations (1) to (2) and the operations (3) to (6) can be executed independently of each other, the present invention first starts this operation by controlling the microprogram controllers 1 and 6. , the microprogram control device 1 manages the microprogram sequence itself and executes the above (1).
~0) is requested to the arithmetic unit 3.

In addition, the microprogram control device 6 also manages the microprogram sequence by itself and
) and instructs the arithmetic unit 8 to follow the addition. In addition to this, the above operations are (1) to C) and (3) to
(6) is executed in parallel, resulting in a significant reduction in processing time.

Furthermore, since there are control signals between the microprogram control device 1 and the arithmetic device 8 and between the microprogram control device 6 and the arithmetic device 3, it is assumed that they are physically separated from each other. does not increase machine cycle time.

As explained above, according to the present invention, since one operation is divided into multiple microprograms and executed in parallel, a system that can shorten machine cycle time and reduce the number of processing cycles can be realized. , an excellent effect can be obtained in that the performance of the information processing device can be significantly improved.
