Abstract
An apparatus architecture is provided which permits an easily programmed apparatus (10) to serve as an equivalent of an integrated circuit chip, and/or as a building block for a large system. The apparatus (10) is connected to a communications bus (40) which receives apparatus parameter, topological, and microinstruction information from a host processor and/or memory (EPROM). The apparatus includes numerous functional blocks (20), a core (30), and a parametric/microinstruction bus (35). The functional blocks include serial (62,66) and parallel ports (68), D/A (54) and A/D (52) converters, and programmable signal processors (300) which serve to process signal data and are connected in any desired manner through a switching matrix (160) located in the core. The topology of the switching matrix (160) is received via the communications bus (40). Parameters and microinstructions for the programmable signal processors (300) are sent via the communications bus (40), the core (30), and the parametric/microinstruction (35) bus. Topological and/or parametric data may be burned into the switch matrix and functional blocks as permanent programmed memory, or held in programmable nonvolatile or…
