表示回路。[Claims for Utility Model Registration] Ultrasonic diagnosis equipped with an image display memory formed by combining a plurality of one memory block composed of a dual port memory having a RAM section for random access and a SAM section for serial access. In the image display circuit of the device, each of the memory blocks is connected in common by an address bus, and a transfer that allows data transfer from the RAM section of each of the memory blocks to the SAM section during the blanking period of the TV horizontal synchronization signal. transfer permission signal generation means for sequentially applying a permission signal to each memory block in time division; and SAM of each memory block in synchronization with the transfer permission signal from the transfer permission signal generation means.
1. An image display circuit for an ultrasonic diagnostic apparatus, comprising: readout start address selection means for sequentially selecting and outputting a readout start address for each memory block when reading out data set in a memory block.
