Development of a Computing System by a Functional Memory Type Parallel Processor.

一种加法功能存储器的研制我们研制了一种专门用于加法的功能存储器。它的存储单元由一个DRAM组成，其面积大约是SRAM的十分之一。PE由两个字和一个位顺序ALU组成。我们设计和制造了LSI来评估其功能和性能。(B)使用功能存储器进行低比特率图像压缩这里，我们开发了一种专门用于矢量量化的功能存储器。它被称为“FMPP-VQ”，代表用于矢量量化的功能存储器型并行处理器。我们已经设计并制造了两个LSI。一种是用于评估的LSI，它由四个PE组成。另一位是。该算法适用于低码率图像压缩。我们开发了一种算法，可以通过29.2kbps的线路以每秒10帧的速度发送QCIF(176*144)视频序列。

(a)Development of a Functional Memory for AdditionWe develop a functional memory specialized for addtion. Its memory cell consists of a DRAM,which area is about 10 times smaller than that of an SRAM.A PE consists of two words and a bit-scrial ALU.We have designed and fabricated LSIs to evaluate is functionality and performance.(b)Low Bit-rate Image Compression Using a Functional MemoryHere, we develop a functional memory specialized for vector quantization. It is called "FMPP-VQ", which stands for Functional Memory Type Parallel Processor for Vector Quantization. We have designed and fabricated two LSIs. One is an LSI for evaluation which consists of four PEs. The other has 64 PEs. It can be applied for low bit-rate image compression. We have developed an algorithm to send a QCIF (176*144) video sequence at 10 frames per second via a 29.2kbps line.
