Patent GB-2050659-A (GB)
Title: Data processing apparatus having opcode extension register
IPC: G06F9/318
Filed: 1979-12-06
Abstract: A Central Processing Unit (CPU) includes a hardware op-code extending register (OER) for storing a code for programmable selection of optional CPU features which modify processor operations defined by the op-code in each instruction. A control section in the CPU decodes both the op-code of a current instruction and the code in the OER, effectively combining the two to form an extended op-code capable of defining a larger set of processor operations than the op-code carried in each instruction. The code in the OER is changed only when the CPU executes an instruction for transferring a new code into OER. Thus the code in OER can remain stationary over many instruction cycles.

Title: Compatible transcodeable and hierarchical digital TV system
IPC: H04N7/00
Filed: 1982-02-01
Abstract: A digital television system in which siganls are sampled at 13.5 MHz and produce an integer number of samples during each horizontal line interval whether the signals are based upon PAL/S.E.C.A.M. or NTSC standards. In order to make the digital system hierarchical and to adapt it for simple transcoding from an NTSC signal sampled at 4 times color subcarrier, the number of samples occurring during the active portion of each horizontal line in the digital system is made equal to 704. Transcoding by interpolation from 4XCS-sampled NTSC video to the digital system is accomplished by selecting a particular number of samples per active line namely 748 such that small blocks of samples can be transcoded independently, which allows interpolation to be achieved simply. A similar transcoding scheme is also described for PAL signals. <IMAGE>
