This paper explores Verilog design for various blocks in Zigbee Transmitter architecture for an acknowledgement frame. The word digital has made a dramatic impact on our society. Developments of digital solutions have been possible due to good digital system design and modeling techniques. Further developments have been made and introduced VLSI in order to reduce size of the architecture, to improve speed of operation, improvements in predictability of the circuit behavior. Digital Zigbee Transmitter comprises of Cyclic Redundancy Check, Bit-to-Symbol block, Symbol-to-chip block, Modulator and Pulse shaping block. The work here is to show how we can design Zigbee transmitter with its specifications by using Verilog with less number of slices and Look up tables (LUTs).
Wirelessnetworks mohit mehra
Wireless networks operate using radio waves to connect devices within a building or campus without cables. There are three main types of wireless network connections: point-to-point links between two devices, point-to-multipoint connecting multiple devices to a central access point, and multipoint-to-multipoint allowing any device to connect to any other. While wireless networks provide mobility and convenience, security measures must be implemented like changing default passwords, filtering devices, and enabling firewalls to prevent unauthorized access to the network.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
