Image Scaler
The Trilinear Technologies AVP-27 Image Scaler provides high quality results for demanding video applications. The AVP-27 balances complexity and resource usage for an optimal solution capable of generating images suitable for display in large screen applications. Host programmable scaler parameters allows the AVP-27 to be configured once on power up or reconfigured on the fly for input specific optimizations.
Using a multiple tap Finite Impulse Response (FIR) based algorithm provides high quality results using time tested frequency domain analysis of the scaling function. Developed in Matlab, the AVP-27 is provided with a complete range of filter settings including ultra-sharp and movie modes. Custom filters can be generated by customers and loaded into the core for testing. Additional non-linear processing elements may be enabled or disabled as needed.
The AVP-27 is delivered as either a technology specific firm core a technology independent soft core and may be implemented on both FPGA and ASIC platforms. The Trilinear Technologies’ development process allows for the migration if soft cores from FPGA to ASIC for prototyping and production solutions with no core modifications. The AVP-27 core offers an optimal solution for both technologies without the typical limitations of performance in ASIC form and area in FPGA form. This flexibility is achieved through a state of the art internal architecture and best in class design practices.
The AVP-27 core ships with a complete ‘C’ reference driver and a fully documented API. The core is available on the Trilinear Technologies’ Vantage Development platform. This FPGA based reference system provides a complete development environment for core evaluation as well as early software development.
