摘要:
A filter processor provides improved capabilities and reduced complexity by inputting and processing lower resolution signals and by generating higher resolution filtered signals. In a preferred embodiment; an incremental filter processor generates incremental input signals, performs incremental processing, and generates multi-bit filtered signals. Input signals are received from radar, sonar, seismic, or other sources; are processed by the filter processor to generate filtered signals; and can be post processed by a post processor. In a preferred embodiment, the input circuit is a serial input and parallel output circuit, such as a delay line or a CCD; the filter processor is an incremental fast Fourier transform processor; and the post processor is an incremental frequency domain correlator. Other post processors include a frequency domain integrator and an RSS post processor to convert coherent signal samples to noncoherent signal samples.

A machine control system employs a general purpose digital computer to directly interact with a machine, providing increased versatility and capability with reduced system cost. Machine control operations are performed under program control by the computer in real time and communicated to the machine through a minimal interface. Machine conditions are sampled under program control by the computer in real time through a minimal interface to the computer. Special system partitioning reduces interconnections and cabling to provide an improved machine interface.

An optical system is provided having an analog image memory, an analog refresh circuit, and analog converters. An optical image is projected on a charge transfer array, such as a CCD imaging array, generating analog image charge samples in the array. The analog image charge samples can be shifted in the array and can be processed with an analog to digital converter to generate digital samples. The digital samples can be processed with a digital processor, such as a stored program digital computer; can be processed with an analog processor, such as a stored program analog computer; and can be processed with an analog filter processor, such as a Fourier transform processor. The analog image signal samples can be refreshed to reduce signal degradation, such as with a bias refresh circuit and a scale factor refresh circuit. Adaptive refreshing can be implemented by storing a reference signal in the analog memory and refreshing the analog image signal samples in response to the reference signal.

Memory technologies for storing filter samples include RAMs and CCDs. Adaptive memory capability and memory servo capability improve memory characteristics. In a RAM embodiment, a detector is used to detect a memory address condition and to control the memory and the memory address register in response thereto. In a CCD embodiment, a detector is used to detect a memory reference signal and to refresh the memory signals in response thereto. Improved memory refresh, memory performance, and memory capacity enhance system characteristics. Improved memory architecture provides advantages of increased speed, lower cost, and efficiency of implementation. Information stored in memory can be scanned out at a rate greater than the addressing rate associated with the memories. This permits higher speed operation with lower cost memories. Use of an output buffer, such as a FIFO, permits normalization of memory clock rates.

A computer system having an improved memory architecture uses a variety of memory speed enhancement features that can be used in combination. For example, the memory is scanned out across memory blocks, unnecessary row addressing operations are detected and eliminated, and the memory is organized to reduce row addressing operations for combinations of instruction accesses interspersed by operand accesses. In a DRAM configuration, unnecessary CAS addressing cycles and RAS addressing cycles are detected and eliminated. A memory address detector circuit in the memory controller determines the nature of the memory cycle; chip select, RAS, or CAS; needed to access stored digital information and deletes unnecessary cycles.

A system for operator interaction is provided using a stored program digital data processor and an audio message sub-system to process digital information and to provide audio messages for operator interaction. The system utilizes a digital data processor to execute program routines to process digital information and to communicate with an operator using audio messages. Digital message information is stored in a digital memory. The digital message information is accessed in response to operator generated signals to provide audio messages, in contrast to the prior art visual messages using displays and printers.
