IPC: G06F3/05
Filed: 1989-05-30
Abstract: A data demodulator assigns a binary value to the signal recorded in a transition cell based on the amplitude of the signal in the transition cell, the amplitudes of the signal in adjacent transition cells and system experience in categorizing how recording non-linearities and system noise effect the signals. The recorded analog signal in the transition cell for which a binary value is to be determined, and the recorded analog signal in a selected number of transition cells adjacent to that cell are each sampled a selected number of times. The amplitude of each of the signal samples is then converted to a digital signal symbol. Portions of the digital signal symbol are concatenated to form an interpretation vector. The vector is then used to enter a stored look-up table, addressing a particular memory location, and the binary value stored in that location is assigned to the transition cell. The look-up table is created based on system experience and the demodulating of known signals. The assigned values for a number of cells may be combined to form a code word which may be decoded using soft decoding techniques. Thus corrections may be made to the estimate assigned to a particular cell using parody checks or other known decoding techniques.

Title: Processor architecture with decoupled instruction fetching
Inventor: POPESCU VALERI
IPC: G06F9/38
Filed: 1990-12-13
Abstract: A processor architecture is described which operates with improved computational efficiency using instruction fetching functions that are decoupled from instruction execution functions by a dynamic register file. The instruction fetching function operates in free-running mode which does not stop if a fetched instruction cannot be executed due to data being unavailable or due to other instruction dependencies. Branch instructions are taken in a predicted direction and the results of execution of all instructions are provisionally stored pending validation or invalidation on the basis of the dependencies becoming available later. For branches of executed instructions that are later invalidated, the results of the executed instructions are flushed from provisional storage and the initial instruction which previously executed at the beginning of a branch on predicted dependencies is re-executed on the actual data that subsequently became available, and all subsequent instructions in such branch are also re-executed on the basis of dependencies actually available from execution of previous instructions in such branch.
