    摘要: A monolithic integrated circuit as may be used in combination with a plurality of sensors for generating respective sensor output signals, which monolithic integrated circuit includes means for converting each sensor output signal to bit-serial digital format, together with some initial processing circuitry comprising a bit-serial multiply-add processor. This processor includes a bit-serial digital multiplier for multiplying a first digital processor input signal in bit-serial form by a second digital processor input signal to generate a digital product signal, a digital adder for adding a third digital processor input signal to the digital product signal to generate a digital sum signal, and means for supplying a digital processor output signal with bits correspond-ing to those of said digital sum signal. A memory system provides memory for storing program instructions, memory for storing successive values of the second digital processor input signal, memory for storing successive values of the third digital processor input signal, and memory for storing successive values of the digital processor output signal as written into the memory system. The first digital processor input signal can be selected from among the sensor output signals as converted to bit-serial digital format. The second digital processor input signals applied to the bit-serial multiply-add processor are at least at selected times read from the memory system, as are the third digital processor input signals applied to the bit-serial multiply-add processor. A controller retrieves stored program instructions in a prescribed order from the memory for storing program instructions and generates control signals for controlling at least the reading and writing of the memory system, as well as the selecting of the first digital processor input signal.

    摘要: Methods and apparatus are disclosed for interfacing a processor bus or CPU to a computation engine to carry out selected tasks with improved efficiency in the computation engine. The computation engine is controlled by an MCC memory-centric controller that provides microcoded operation of the engine independently of the CPU. Essential interfacing between the processor bus and the computation engine includes storing microcode in a separate memory accessible to the MCC controller, or downloading microcode from the CPU/processor bus as needed for a specific task. The MCC controller can reconfigure the computation engine, such as memory block allocation, word size, etc. under microcode control, so that new or user-proprietary algorithms such as those used in dsp can be implemented using a standard computation engine without redesign. Execution of selected tasks on the computation engine is triggered automatically by decoding instructions that appear on the processor bus. Such tasks can include dsp, compression, decompression, encryption or other complex computations, and further can include downloading new or updated microcode into the computation engine desired.

    摘要: Architectures and circuits are described for various implementations of a memory-centric computing system for DSP and other compute-intensive applications. A shared, reconfigurable memory system is accessible to both a host processor or controller and to one or more execution units such as a DSP execution unit. By swapping memory space between the processor and the execution unit so as to support continuous execution and I/O, improved performance is achieved while cost is reduced. The shared memory system includes multiple reconfigurable memory segments to allow allocation of various amounts of memory to respective execution units or I/O or DMA channels as needed to optimize performance. A "virtual two-port" solution also is described for using single-port memory in the shared configuration with multiple address sources.
