Patent number: 6173419Abstract: An emulator is used to debug software operating on a target micro-controller in a target circuit environment. The emulator contains a field programmable gate array that is programmed to contain an emulated target micro-controller and an emulated monitoring circuit which monitors the operations of the micro-controller. The emulated target micro-controller receives signals from the target circuit environment. The signals from the target circuit environment are communicated to the emulated target micro-controller by one or more channels, such as a data channel and a timing channel. The number of channels is limited so that signals from the target environment do not degrade the performance of the emulator. A host computer contains a software debug program which works with the emulated monitoring circuit to monitor the emulated micro-controller.Type: GrantFiled: May 14, 1998Date of Patent: January 9, 2001Assignee: Advanced Technology Materials, Inc.Inventor: Philip C.

Patent number: 6145020Abstract: The present invention is an enhanced peripheral controller communicating between a microcontroller and multiple peripherals that increases the speed with which configuration data sets are loaded. The enhanced peripheral controller includes a programmable logic array (PLA) and an FeRAM array. A reconfigurable peripheral controller is programmed onto the programmable logic array from a configuration data set for one of multiple peripherals. The reconfigurable peripheral controller is reprogrammed each time a new peripheral is connected to the microcontroller. The FeRAM array contains the configuration data set for programming the reconfigurable peripheral controller onto the programmable logic array. The FeRAM will receive a different configuration data set for each different peripheral to be programmed onto the PLA. Because the FeRAM operates at the speed of RAM, it receives the configuration data set for each peripheral on the fly as the microcontroller operates.Type: GrantFiled: May 14, 1998Date of Patent: November 7, 2000Assignee: Advanced Technology Materials, Inc.Inventor: Philip C.
