Dual Core (DSP and MCU) - Industrial Control Applications The SH99F100 is a dual-core (DSP and MCU) chip for industrial control applications such as motor speed regulation and variable frequency power supplies. The MCU can be used to handle switching, input and output, and communication, while the DSP only needs to focus on the operation of the control algorithm. The DSP architecture consists of three parallel computing units (ALU, MAC, SHIFTER), two independent address generators (DAGs), and a powerful program sequencer (PSQ). The calculation unit provides the computational functions that all processors can provide, including single-cycle multiply/accumulate, bit operations, shift operations, and more. The dual data address generator allows the processor to simultaneously fetch two data from two data banks (Data Memory and Program Memory) in one cycle. The program sequencer implements single-cycle operation of all instructions, fast interrupt response, and nested cycles of non-CPU intervention. The 16-bit PWM module, Quadrature Coding Interface (QEI) and 14-bit pipelined ADC and op amp (OP) act as internal peripherals for the DSP core, enabling easy implementation of multiple industrial control algorithms. The MCU core is a high-speed and high-efficiency 8051-compatible core. Compared with the traditional 8051 chip, the MCU core has faster running performance and superior performance. Its resources include built-in 256-byte SRAM and external 3840-byte SRAM. Three 16-bit timers and three external interrupts, as well as two enhanced UARTs and one SPI interface.

The cat7 Lan Cable are an eight-core Shield wire. Each pair has a Shield layer (commonly called a Foil Shield), and then a Shield layer (commonly called a Braided screen Shield) outside the eight cores, with the same connection as the RJ-45.The highest transmission frequency of the CAT7 Ethernet Cable S/FTP is 600MHz, and the transmission frequency of the CAT7 Network Cable is 1000MHz.
There are a number of significant differences between the six and seven cabling systems, the most obvious of which is bandwidth.The CAT6 cable of channels provide a comprehensive attenuation to crosspoint ratio of at least 200MHZ and an overall bandwidth of 250MHZ. CAT7 of systems can provide at least 500MHZ of comprehensive attenuation to crosspoking ratio and 600MHZ of overall bandwidth.
The proliferation of broadband applications has created a need for more bandwidth.For example, a typical CAT7 channel can provide a bandwidth of 862MHZ for the transmission of video signals, analog audio signals on another pair, and high-speed LAN information on a third or fourth pair.
Another difference between the CAT6 patch cable and cat7 patch cable systems is their structure.The six types of wiring systems can use either UTP or STP.The seven types of systems are based only on shielded cables.In the cat7 network cables, each pair has a shield layer, and four pairs of wires together have a common shield layer.In terms of physical structure, the additional shielding layer makes the CAT7 Ethernet Cable have a larger diameter.
Another important difference is its ability to connect hardware. The parameters of the cat7 patch cable of systems require that all pairs of wires provide at least 60DB of integrated proximal winding at 600MHZ.The cat6 systems only require 43dB at 100MHZ and 46dB at 250MHZ for the cat6 patch cable.
