A memory interface device of the present invention includes: an input buffer including a plurality of input areas; an output buffer including a plurality of output areas; and a control section for controlling the input buffer, the output buffer and a single port memory. The control section controls the input buffer and the single port memory so as to transfer a signal stored in one of the input areas of the input buffer to the single port memory while storing an input signal in another one of the input areas of the input buffer. The control section controls the output buffer and the single port memory so as to output as an output signal a signal stored in one of the output areas of the output buffer while transferring a signal stored in the single port memory to another one of the output areas of the output buffer.

Television receiver, video signal processing device, image processing device and image processing method

A single-instruction multiple-data (SIMD) processor (10) that incorporates features for horizontal scaling of video data. The processor (10) has a data input register (11) that is operable to store input data word in sequential locations in the data input register (11) and transfer the input data words to an array of processing elements. The processor (10) also has an output data register (16) operable to receive data output words from the array of processing elements and to output said data output words from sequential locations of said output data array. An input skip signal input to the processor causes a sequential data write operation to skip a location of the input data register while an output skip signal to the processor causes a sequential data read operation to skip a location of the output data register.

Single-instruction multiple-data processor with input and output

A method of reading a memory cell containing an access transistor, a word line and a memory storage for holding information. The access transistor having a control terminal is connected to the word line. The memory storage is connected to the access transistor and thereby to a sense amplifier through a bit line. The access transistor, operating in a conductive state, is responsive to the word line. The bit line is precharged to an intermediate voltage level greater than a low threshold level and less than an upper limit level. The bit line is discharged from the intermediate voltage level to produce a low voltage level in a prescribed time if the memory storage holds memory information of a first state. The bit line is charged to approximately the upper limit level in the prescribed time if the memory storage holds memory information of a second state. The voltage of the bit line is determined by the sense amplifier after the prescribed time so that the memory information is read.
