<p>A processor (100) is provided that is a programmable digital signal processor (DSP) with variable instruction length, offering both high code density and easy programming. Architecture and instruction set are optimized for low power consumption and high efficiency execution of DSP algorithms, such as for wireless telephones, as well as pure control tasks. An instruction (1003) is decoded and accesses a data item in accordance with an address field (1003a). Another instruction (1002) is decoded and accesses a data item in accordance with an address field (1002a); but in a different manner due to an instruction qualifier (1002b). The instruction qualifier is executed in an implicitly parallel manner with the qualified instruction (1002).</p> |
