摘要:
DSP architectures having improved performance are described. In an exemplary architecture, a DSP includes two MAC units and two ALUs, where one of the ALUs replaces an adder for one of the two MAC units. This DSP may be configured to operate in a dual-MAC/single-ALU configuration, a single-MAC/dual-ALU configuration, or a dual-MAC/dual-ALU configuration. This flexibility allows the DSP to handle various types of signal processing operations and improves utilization of the available hardware. The DSP architectures further includes pipeline registers that break up critical paths and allow operations at a higher clock speed for greater throughput.
