Also, 64KBytes is equal to the segmentation value in the 186 based systems as well as the page length of the Series 2 memory card. This makes it very attractive to have pages of 64KBytes each. The additional overhead added due to setting up of page is very small compared to the space which is made available for data storage or code execution and page set-up changes would be needed only while going to the next 64KByte boundary. For smoother execution of code, paging may not be the best solution, however, for the data storage, paging is one of the best solutions available. The described add-in board increases the addressable memory space of both existing and future 80C186 platforms, with little modifications in some cases.
Flash memories are non-volatile in nature.
Power saving modes of the Flash memory card allow for power saving features in multiple operating conditions. Flash cards would have the capability of being removed from the field unit and transferred to computer systems for data retrieval and analysis. Develop, test, debug and download of software to embedded systems can be accomplished using Intel Flash memory cards. Figure 1. details the block diagram of the system. The map of memory and IO devices in this system is as shown in Figure 2.
