摘要： PURPOSE:To convert the coordinate value of virtual two-dimensional space or image information represented in the number of picture elements to the address information of memory efficiently and at high speed when a two-dimensional image stored in the memory is processed. CONSTITUTION:When the coordinate value of the virtual two-dimensional space or the image information of the two-dimensional image represented in the number of picture elements stored in a register 105 is changed, a change information memory device 101 stores information that a content is changed, and an interrupt generator 102 requests interrupt processing when it is changed. A controller 103 converts the image information represented in virtual space to the address information of the memory 106 only when the content of the register 105 is changed based on interruption.

摘要： PURPOSE:To attain high speed transmission of a clock signal and a data signal by sending 1st and 2nd optical signals converted by an electrooptic conversion means while synthesizing them, demultiplexing the result depending on frequencies by a demultiplex means and converting them into electric signals separately. CONSTITUTION:In applying a clock to a clock signal line 101, it is converted into the intensity signal of light by a 2nd electrooptic conversion means 131 and the result is outputted to an optical fiber 161. Similarly, the data is converted into the light intensity signal by a 1st electrooptic conversion means 132 and outputted to the optical fiber 162. The both are synthesized by a synthesizer 150 and the result is outputted to a transmission means 120. Since the stimulated frequency of laser diodes 131, 132 is designed to be different from each other such as f0 and f1, they can be separated even after the mixing. The light signal to be sent is separated by a frequency filter of a demultiplex means 151 and sent to optical fibers 163, 164. The optical signals are converted into electric signals by photodiodes 141, 142 and clock and data signals are obtained.

摘要： PURPOSE:To realize a fast image processing, by dividing image data to be processed into plural parts, processing them separately in parallel, and setting the results of the above processing. CONSTITUTION:A row of image elements read out from an image memory device 255 are read out in series after being stored in an input buffer 251, and are distributed to odd image elements and even image elements by a distributor 252, then, inputted to original image registers 214 and 224. Stored image elements are selected according to the instruction of original image element pointers 213 and 223 decided by the functions of residual registers 210 and 220, and adders 216 and 226, etc., and the density of then are transferred and stored in result image registers 215 and 225. The contents of them are collected to corresponding image elements by a collector 253, and are stored in a result output buffer 254, and are written on the image memory device 255.

摘要： PURPOSE:To simplify the structure of a data processing means by adding boundary information to an address of the boundary of a processing area by an address generating means, transferring to a picture storing means and transferring data and the boundary information synchronously to the data processing means from the picture storing means at the time of reading picture data by the data processing means. CONSTITUTION:A first boundary information means 18 for transferring the boundary information of the processing area between the address generating means 101 and the picture storing means 104, 106, 108, and a second boundary information transferring means 19 for transferring the boundary information of the processing area between the picture storing means 104, 106, 108 and picture processing means 103, 105, 107 are provided. Namely, when the address generating means 101 generates the address of the data to be processed, information indicating whether the data to be processed is the boundary of an area to be processed or not is transferred to the picture storing means 104, 106, 108 synchronously therewith by the address generating means 101 and when the picture processing means 103, 105, 107 read the data to be processed from the picture storing means 104, 106, 108, the information indicating whether the data to be processed is the boundary of the area to be processed or not is transferred to the picture processing means 103, 105, 107 from the picture storing means 104, 106, 108.

摘要： PURPOSE:To reduce stack capacity and to realize a high speed processing in an auxiliary processor which executes the auxiliary processing of a host processor in a computer system. CONSTITUTION:Information supplied from a selection means 14 is interpreted When the information is a command branching to a subroutine, the return address of a counting means 11 is stored in a stack 17 if the content of a third storage means 15 is one, and a previously decided special value, zero, for example, is stored in the stack 17 if the content of the storage means 15 is zero. The content of the storage means 15 is updated to one, and the address is generated from the command supplied from the selection means 14 after the processings, whereby the value is stored in the counting means 11. When information supplied from the selection mans 14 is the command restored from the subroutine, information is fetched from the stack 17. When the information is the specified value '0', the content of the storage means 15 is updated to zero. When it is not the specified value '0', the address information is stored in the counting means 11.
