Description: VHDL实现SPI功能源代码
-- The SPI bus is a 3 wire bus that in effect links a serial shift
-- register between the "master" and the "slave". Typically both the
-- master and slave have an 8 bit shift register so the combined
-- register is 16 bits. When an SPI transfer takes place, the master and
-- slave shift their shift registers 8 bits and thus exchange their 8
-- bit register values.-SPI realize the functional VHDL source code The SPI bus is a 3 wire bus that in effect links a serial shift register between the

Description: 一个4比特移位寄存器,活跃在不断上升的边缘的时钟。登记应能转移左、右移,接受连续剧和平行(负荷)输入,而有一个异步预设(“1111”)和清晰的(“0000”)的能力。-a 4-bit shift register which is active on the rising edge of the clock. The register should be able to shift left, shift right, accept a serial and parallel (load) input, and have an asynchronous preset (“1111”) and clear(“0000”) capability.
