specific Embodiment

[0089] The specific embodiment uses the JTAG state machine to realize the simulation of the GPIO port of the DSP to the JTAG port, as attached Image 6 As shown, the various states and jump conditions of the JTAG state machine are briefly introduced as follows:

[0090] (1) Test-Logic-Reset test logic reset state

[0091] In this state, the test logic is disabled to allow the chip to operate normally, and reading the IDCODE register will disable the test logic. No matter what state the TAP controller is in, as long as the TMS signal is kept high at the rising edge of 5 consecutive TCK signals, TAP will enter the Test-Logic-Reset state. If the TMS signal is always high, then TAP It will remain in the Test-Logic-Reset state, and the TRST signal can also force the TAP to enter the Test-Logic-Reset state. If the TAP is in the Test-Logic-Reset state, if the TMS signal is low at the next rising edge of TCK, then the TAP will be switched to the Run-Test-Idle state.

Abstract

The invention discloses a remote update system and method for a programmable logic device. The system comprises a computer, a processor, a programmable logic device and a configuration unit, wherein the processor, the programmable logic device and the configuration unit are mutually connected; the computer sends configuration file data to the processor; and the processor simulates the programmable logic device to configure the time sequence and the behavior of a JTAG (Joint Test Action Group) port of the configuration unit through a GPIO (General Purpose Input / Output) port according to the configuration file data so as to realize an ISP (In System Programming) operation that the processor configures the configuration unit. The technical problem that a traditional dedicated simulator programming loading way cannot meet requirements since on-site logic programming is not suitable for workers under complex application conditions, especially under the environment with high confidentiality requirements, can be solved.

Description

Technical field [0001] The present invention relates to the technical field of electronic circuits, in particular to a remote update system and method applied to programmable logic devices. Background technique [0002] Programmable logic device FPGA is a kind of logic circuit device, which is characterized by static repeatable programming or online dynamic reconfiguration. The hardware functions of this circuit can be modified by programming like software, which makes circuit design and product upgrades very convenient, and greatly improves the flexibility and universal capabilities of the electronic system. At present, many chip suppliers, such as XILINX or ALTERA, can provide various types of FPGA or CPLD. [0003] Programmable logic devices are more and more widely used in embedded systems. In the design stage and various stages after on-site operation, problems such as design upgrades, modifications, and tests may be encountered. The logic device with in-system programmable...
