该论文介绍了一款支持2G/3G/4G多标准及载波聚合的蜂窝调制解调器,采用28nm CMOS工艺实现。通过可编程DSP架构和SIMD操作,解决了多标准兼容与高吞吐量需求之间的矛盾。

This high throughput is the result of executing multiple single-instruction-multiple-data (SIMD) operations (256b wide), as well as multiple scalar operations in a very-long instruction word (VLIW) fashion, as illustrated in Fig. 10.8.3. Compared to [3], the current EVP not only operates on fixed-point data, but also on floating-point data. The 32+4 floating-point multipliers support 8+1 complex multiply-accumulate operations every clock
