Abstract: A relatively compact frozen custard machine is provided. The frozen custard machine includes a housing. The housing is configured to support a first evaporator, a second evaporator, a compressor, and a condenser. The housing is configured to be supported by an elevated surface, such as an existing countertop.

Abstract: A programmable application specific integrated circuit (ASIC) for implementing operations that involve a plurality of computational functions. The programmable ASIC comprises a plurality of fixed functions and programmable switch logic. Each of the plurality of fixed functions is parameterized such that its operational characteristics are programmable using different operating parameters. In addition, each of the plurality of fixed functions inputs and outputs data in accordance with common interface rules. The programmable switch logic is configurable to link two or more of the fixed functions in a sequence to perform desired operations. The fixed functions are implemented using “hard” or fixed digital logic gates such as those in an ASIC.
