ABSTRACT:
A programmable integrated signal processor ("SPROC") is provided having a multiported central memory unit (RAM), a program memory, at least one, and preferably a plurality of digital processors coupled to the multiported RAM and to the program memory, a data flow manager which controls external data flowing into the SPROC and processed data flowing out of the SPROC by acting as an interface of such data with the multiported RAM, input and output ports coupled to the DFM and acting as serial interfaces for the SPROC, and a host port permitting the programming of the SPROC and acting as a parallel interface to the SPROC. SPROCs may be coupled via the input and output ports to provide a system. The SPROC architecture permits the SPROC system to be computationally expandable, to have low latency and parasitic overhead for real time I/O, to efficiently execute a multiple of asynchronous processes, and to easily interface with microprocessors of various formats. The SPROC architecture in conjunction with a compiler and user interface system permits a user to "sketch and realize" complex circuits in the SPROC. An access port coupled to the multiported data RAM and the program RAM is provided for debugging purposes and permits reading and writing to data and program RAM memory locations. A probe permits monitoring of a memory location and provides an analog signal indicative thereof. The SPROC accomplishes for signal processing that which a microprocessor accomplishes for logic processing, and is further also easily realized in silicon.
