Abstract:
The feed for the subject receiver-on-chip is a 30 Mhz to 18 Mhz Rf input (42), which is coupled to an RF pre-select and attenuation or notch filter circuit (44), which is off-chip. The out put of this circuit is amplified by a low noise amplifier LNA (46) and is either switched between a low band pass filter (48) or mixer (50) is used in a single down conversion stage, with the mixer (50) being driven by either 8, 10 or 12 GHz local oscillators on line (52) from a clock and local oscillator (54).
Abstract:
A multi-level framework that allows an application to be developed independent of the chip or board, and any dependency is built in as part of the framework of the field programmable device (FPD). A shell configuration called a 'wrapper' has a standard look, feel and form factor that provides the interface between the high density language (HDL) application and a standardized and board independent HDL shell, thus isolating the HDL core. A second wrapper is a board specific HDL shell that interacts with the standardized shell. Any application that has the same look, feel and form factor has a common interface that allows various system boards to communicate, providing a mechanism for creating a HDL application component independent of the hardware. An outer shell binds the system to some board and talks to the application program interface (API) layer and the code layer to the outside world, such as the operating system.
Abstract:
A layered mechanism (Fig. 1) for integrating programmable devices into software based frameworks for distributed processing wherein the software framework (16) interfaces with an adaptation layer (10), which in turn interfaces with a programmable device (12), such as a field programmable gate array (FPGA). The adaptation layer (10) specifies and enforces compatible electrical, physical and logical interfaces between the programmable device (12) and the software-based framework (16) of which the device (12), the application running on it, and the adaptation layer (10) form a component.
