Microprocessor memory direct accessing system - has buffer interface controlling data addressing and transfer between memory, drive circuit and logic circuitry

摘要

The system comprises a buffer interface (5) which during a period of accessing of the drive circuit from a memory supplies data addresses contained in the memory. It also maintains the continuous circulation of corresponding data between the drive circuit and the memory. This also operates during the rest of the drive circuit accessing period and puts into memory the required data till the termination of the accessing period. It can also operate to break the data circulation towards the memory and the corresp. logic circuitry to control the buffer interface inhibition.
