Abstract

1404664 Data processing systems TEXAS INSTRUMENTS Inc 26 July 1972 [26 Oct 1971] 34963/72 Heading G4A A CPU 34 has a random access central memory, e.g. MOS modules 12-19, and a bulk memory extension 49 which, in one mode, is directly addressable and, in a second mode, transfers variable length data blocks between itself and the central memory using a data channel controller. There are five types of memory in the system of Fig. 1, these being (in ascending order of access time); CPU buffers, random access memory units 12-19, memory extension 49, disc storage units 38, 39 and tape units 27-32. Also provided are a twin CRT keyboard console 23 which is operator controlled for interrupt and hardware/software checkout, a card reader 24, a card punch unit 25 and a printer 26. A memory control unit 20 controls units 12-19 (providing gating mapping and protection), is connected to the disc units 38, 39 by a disc interface unit 37 and a data channel unit (a wired program computer), and is connected to the units 27-32 and 24-26 by a peripheral processing unit 22 including eight virtual processors. The units connected to unit 20 are serviced on a fixed priority basis and there are priorities for the memory extension.
