The D1088 is a 5-stage pipeline integer processor with integrated DSP offering 130 DSP SIMD (single instruction, multiple data) instructions. Targeting the real time processing requirements of power-constrained multimedia applications, At 90nm low power process, the D1088 delivers 588 DMIPS, 134 percent higher than the competing offerings. When measured with the popular Whetstone floating-point benchmark , the D1088 achieves 92 percent better performance. When running the popular and comprehensive (over 200) DSP libraries, the D1088 is 116 percent faster with half the code size. Even with the above advantages, D1088 still comes with a little smaller die area and power per MHz. The D1088’s optimized DSP libraries and C/C++ compiler make algorithm programming easier.

Tightly integrated Integer and DSP processor architectures are not new, but most were designed for applications where power was not as much a constraint as it is today. The new D1088 was designed with this new reality in mind. It contains functionality to enhance efficiency and reduce code size. For example, to significantly boost the computational performance in matrix, filtering, Fourier Transform, and statistics functions, it can execute 4-way 8-bit, or 2-way 16-bit SIMD instructions in a single latency as well as 8-bit and 16-bit SIMD instructions. In addition, for multimedia applications, the D1088 also supports 64-bit as add, subtract, and multiply mixed computation.
