Abstract
A programmable signal processing circuit has an instruction processing circuit (), which has an instruction set that comprises a demapping instruction. The instruction processing circuit () has an operand input () for receiving a complex number operand of the demapping instruction from a register file () and a result output () for writing a demapping result of the demapping instruction to the register file (). The instruction processing circuit () determines at least four bit metrics in response to the demapping instruction, each indicating a relative position of the complex number relative to respective border line in a complex plane. The instruction processing circuit () writes a combination of the at least four bit metrics together to the result output () in the demapping result.
