    Abstract: Apparatus for fetching instructions to an instruction register of a central processing unit, including instruction buffers for storing instructions prior to their execution in the CPU (lookahead) and apparatus for storing instructions which have been executed in the CPU (look-behind) in anticipation of their further use in, for example, programming loops. The look-behind apparatus comprises a multi-word buffer with its associated data register. The buffer data register, in addition to its function as part of the look-behind apparatus, also provides an additional level of look-ahead.

    Abstract: 1,070,426. Electric digital calculators. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 22, 1964 [Dec. 23, 1963], No. 52007/64. Heading G4A. Data processing apparatus comprises means to derive cyclic clock pulses from timing signals supplied thereto from a source via means which are responsive to a stop signal from a bi-stable stop circuit to superimpose a steady signal on said timing signals whereby the clock pulse deriving means is stopped in a particular state, and resetting means responsive to said source to reset said stop circuit only when the polarity of the source is the same as the polarity of said steady signal. The subject matter is included in Specification 1,070,423 which is referred to.
