The CC1100 is a second-generation digital multimedia processor with the appearance shown in Figure 1. The CC1100 is designed with a programmable multi-core processor SoC architecture. The main CPU is a superscalar RISC processor with a frequency of 350MHz. It runs the Linux operating system. It can execute 4 instructions per instruction cycle and supports hardware dual-threading technology. Video codec work is done in stages by three programmable but different architecture sub-processors (256-bit vector processor, MoTIon EsTImaTIon engine and Entropy engine). The heterogeneous multi-DSP architecture decomposes the processing process of complex moving images into multiple relatively independent processes according to its function and computational complexity characteristics, and then uses different architectures of processors to adapt and process the motion image in the encoding and decoding process. Complexity changes, balance performance, flexibility and power consumption. Figure 2 is a block diagram of the internal structure of the CC1100. The innovative architecture design allows the CC1100 to handle video CODECs in a variety of formats with high performance at a lower frequency. The post-processing and analog output tasks of the video display are done by the hardware unit, which supports four OSD layer image display overlays, scaling and 2D acceleration. The interconnection of all internal function blocks is done by the high speed DMA channel and the internal bus. The integrated memory controller supports dual-channel DDRII-667 memory, which provides enough storage bandwidth for complex video processing. The CC1100 integrates peripheral interfaces such as PCI-Express, SATA-II, USB2.0 OTG and SDIO, which can be connected to networks, high-speed hard disks, SD cards and portable USB devices. The difference with the T1 product is that the T1 DSP has developed earlier and has higher versatility. It can process audio, video, medical information, scientific computing and other data. TI's DSP video encoding and decoding work is done with a general-purpose processor. . Most general-purpose video SoCs use a general-purpose programmable DSP to process video, and simply increase the frequency to ensure that video processing requires computing resources. The increase in frequency will increase the complexity and cost of PCB design. There are also some low-end video SoCs that process video entirely through hardware modules. At the expense of flexibility in exchange for the performance required for video processing. The CC1100's multimedia chip is a DSP optimized for audio, video and imaging applications. It is highly targeted, efficient and compatible with the latest network technologies (Gigabit Ethernet and 802.11n WiFi). The CC1100's video codec work is coordinated in stages by three programmable but different architecture sub-processors. Compared to general purpose DSP or DSP SoC.
