Abstract

A compressor circuit C serves as a common data channel for individually selected storage registers SR-1 and SR-2. Each idler cell compressor circuit C is occupied by a magnetic domain, supplied each cycle of rotation of an in-plane orientation field H to the input of compressor circuit C by a magnetic domain generator C. As field H rotates through a complete cycle, when all idler positions are filled, a domain is propagated from the output of compressor circuit C where it is detected and sensed by a sensor S, and ultimately destroyed at annihilator A-1. Data is communicated through the compressor circuit C selectively from storage registers SR-1 and SR-2, through their respective register interfaces RI-1 and RI-2 to individual idler cells IC-1 and IC-2.

Storage System Using Shared Compressor Circuit

A compressor circuit C serves as a common data channel for individually selected storage registers SR-1 and SR-2. Each idler cell compressor circuit C is occupied by a magnetic domain, supplied each cycle of rotation of an in-plane orientation field H to the input of compressor circuit C by a magnetic domain generator C. As field H rotates through a complete cycle, when all idler positions are filled, a domain is propagated from the output of compressor circuit C where it is detected and sensed by a sensor S, and ultimately destroyed at annihilator A-1. Data is communicated through the compressor circuit C selectively from storage registers SR-1 and SR-2, through their respective register interfaces RI-1 and RI-2 to individual idler cells IC-1 and IC-2. Domains in SR-1 and SR-2 are circulated via field H propagation through the interfaces RI-1 and RI-2, causing domains in idler cells IC-1 and IC-2 to be displaced into displacement channels SC-1 and DC-2, whereupon they ultimately are destroyed by annihilators A-2 and A-3.

Fig. 1 shows the condition of compressor circuit C at phase 1 of orientation field H. At that time, a 1-bit represented by domain D(0) is in position 1 at T-bar
20. At phase 2 of field H, as seen in Fig. 2, domain D(0) is at position 2 of Y-bar 21 at interface RI-1. At this time also, a new domain D(1) is generated by generator G. Since all idler cells are occupied by domains, a domain D(2) is advanced to output position 1" to be detected by sensor S. Fig. 3...
