The decompressors are to use a bigger version of the microcontroller. static HTML files for embedded web servers. tiny in ROM, but the benefits of compression means you reclaim more space in your device for the features n Decompressing and Processing Data Compression Mode you're trying to add. emCompress features two decompression functions.

The tailored for RAM use, you can decompress static complete data is decompressed and stored in a content early in your application and not devote RAM user-provided memory buffer. Although the buffer to decompression buffers. can be temporary, this requires to have enough free n Performance and Memory Footprint yield good compression ratios, but even without temporary memory for the complete uncompressed data and RAM, good compression ratios can be achieved in many n Typical example – the workspace.

The amount of ROM that emCompress uses for 512 bytes. For instance, configuring an FPGA is one of the first The second function is decompression in streamed decompression varies with the codec selected between 0.5 things that an application will do, decompressing a mode. emCompress will use a small temporary buffer kByte and 2.1 kByte.

SEGGER Microcontroller is a full-range supplier of hardware and software development tools as well as middleware for embedded systems – in brief: The Embedded Experts.
The company offers support throughout the whole development process with affordable, high quality, flexible and easy-to-use tools and components: Starting with its own IDE SEGGER Embedded Studio, debugging with the industry-leading J-Link, tying in Microcontroller peripherals via its Middleware, and finally implementing the software on the target through its own Flasher programmers.
SEGGER relies on closed-loop development: Its products have to prove their worth in daily use by the developers. That’s why: It simply works!
Software products include, among others: embOS (RTOS), emWin (GUI), emFile (File System), emUSB (USB host and device stack) and embOS/IP (TCP/IP stack). With emSSL and emSecure, a unique software to generate and verify digital signatures, SEGGER is offering solutions for secure communication as well as data and product security, meeting the needs of the rapidly evolving IoT.
The highly integrated, cost-effective tools comprise the Flasher flash programmer and the J-Link/ J-Trace debug probe.
