Title: Double buffering in multi-processor
Inventor: BALDWIN DAVID ROBERT
IPC: G06F15/78
Filed: 1988-03-23
Abstract: A dual port memory 430 is used, partitioned in software so that the top half of the memory is allocated to the control processor, (110) and the bottom half to the floating point is processor (130). This allocation is switched when both processors set respective flag bits indicating that they are ready to switch. On accesses to this memory, additional bits tag the access as "physical," "logical," or "preview". A physical access is interpreted as a literal address within the full memory, and the double buffering is ignored. A logical access is supplemented by an additional address bit, determined by the double buffering switch state. A preview access is used for read access only, and goes to the opposite bank of memory from that which would be accessed in a logical access. The use of preview can be particularly advantageous in avoiding data flow inefficiencies at synchronization points in pipelined algorithms. Preferably double buffering is used in a register file at the interface between the numeric processor and the large data cache memory (140) in the multiprocessor system. The partitioning of the register file avoids data collisions in the cache memory. <IMAGE>

Title: Coulometric titration system
Inventor: ROBERTSON GEORGE
IPC: G01N27/44
Filed: 1989-09-25
Abstract: A titration system comprises reaction cell 1 containing detection electrodes 2 and electrolysis electrodes 3 immersed in a solution 4 of the substance to be analysed, and a constant current generator 13 which supplies a constant electrolysis current at one of a plurality of levels. An electrolysis current monitor 14 generates a signal S3 when the constant current level fluctuates or becomes unstable, and signal S3 causes the microprocessor 9 to change the level of the constant current signal. A detection means, 6, 7, 8 coupled to the detection electrodes 2 generates a signal corresponding to the polarization of the solution 4 which may also cause alteration of the constant current. The microprocessor 9 includes a counter for integrating the current required for the electrolysis until an end point is reached. The titration system maintains a constant current level and integrates at an appropriate rate even if increases in electrical resistance in the solution prevent maintenance of a higher level of constant current. The system may be used to determine water in crude oil. <IMAGE>
