Abstract: A direct memory access system consists of a direct memory access controller establishing a direct memory access data channel and including a first interface for coupling to a memory. A second interface is for coupling to a plurality of nodes. And a processor is coupled to the direct memory access controller and coupled to the second interface, wherein the processor configures the direct memory access data channel to transfer data between a programmably selectable respective one or more of the plurality of nodes and the memory. In some embodiments, the plurality of nodes are a digital signal processor memory and a host processor memory of a multi-media processor platform to be implemented in a wireless multi-media handheld telephone.

Abstract: A Wallace tree structure such as that used in a digital signal processor (DSP) is arranged to sum vectors. The structure has a number of adder stages, each of which may have half adders with two input nodes, and full adders with three input nodes. The structure is designed with reference to the vectors to be summed. The number of full- and half-adders in each stage and the arrangement of vector inputs depends upon their characteristics. An algorithm calculates the possible tree structures and input arrangements, and selects an optimum design having a small final stage ripple adder after the last stage of the Wallace tree structure, the design being based upon the characteristics of the vector inputs. This leads to reduced propagation delay and a reduced amount of semiconductor material for implementation of the DSP.

Abstract: A Wallace tree structure such as that used in a DSP is arranged to sum vectors. The structure has a number of adder stages (365, 370, 375), each of which may have half adders (300) with two input nodes, and full adders (310) with three input nodes. The structure is designed with reference to the vectors to be summed. The number of full- and half-adders in each stage and the arrangement of vector inputs depends upon their characteristics. An algorithm calculates the possible tree structures and input arrangements, and selects an optimum design having a small final stage ripple adder (380), the design being based upon the characteristics of the vector inputs. This leads to reduced propagation delay and a reduced amount of semiconductor material for implementation of the DSP.

Abstract: A method for executing instructions on an application-specific microprocessor having a machine language is described. Microcontroller-like instructions are provided in a virtual language for execution on the processor. High-level DSP-like functions are compiled into DSP-like instructions in the machine language for execution on the processor. The microcontroller-like instructions are combined with the DSP-like instructions to produce a program, the program having a virtual language portion and a machine language portion respectively. When the program is executed, the virtual language portion of the program is translated into machine language instructions, and the machine language portion of the program is directly executed, such that the application-specific microprocessor executes both the DSP-like instructions and the microcontroller-like instructions.

Abstract: An interface circuit (14) that allows for a flexible three-way interface between a microprocessor (12), an ASIC cell block (16), and the external world has been provided wherein the microprocessor and the ASIC cell block are fabricated within a gate array (10). The interface circuit provides circuitry for each I/O pin (22, 23, 24) of the microprocessor to allow it to readily interface with the customer designed ASIC cell block or external devices via the ASIC I/O pads (20). The interface circuit also allows isolated testing of only the microprocessor, of only the ASIC cell block, or of both the microprocessor and the ASIC cell block. The interface circuit and the microprocessor are fully diffused and fixed-placed within the gate array while the ASIC cell block may be utilized by a customer to design a circuit to perform a customer defined function.
