IP Core Design of 8253 Based on Quartus II

Provided by ALTERA FPGA/CPLD Quartus II development software development platform. programmable timer/counter 8253s functions and internal circuitry as the basis, combined with programmable gate array (FPGA) products FLEX10KE characteristics, using VHDL hardware description language and schematic Figure two ways 8253 for hierarchical, modular, parameterized logic design. The completed design will be configured to the chip of FLEX10KE,and Proved to be correct.
