| Research Abstract |
(a)Development of a Functional Memory for Addition
We 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 Memory
Here, 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.
