Crosswell C Collins

Title: Crosswell C Collins: Innovator in Network Technology

Introduction

Crosswell C Collins is a notable inventor based in Oakland, CA (US). He has made significant contributions to the field of network technology, holding a total of 4 patents. His work primarily focuses on integrating advanced networking capabilities into compact silicon chip designs.

Latest Patents

One of Collins' latest patents is a network router integrated onto a silicon chip. This innovative router design includes an internal bus that connects multiple data receive and transmit channels to a central processing unit. Each channel features an external interface for connecting to various LAN or WAN networks. The serial channels can be converted into one or more time division multiplexed (TDM) channels. A time slot assigner (TSA) is employed to assemble and disassemble data packets transferred in TDM formats, such as ISDN. The TSA is programmable to accommodate different TDM formats, enhancing the router's versatility. Additionally, a single direct memory access controller (DMAC) is coupled to each serial channel and an Ethernet channel, facilitating data transfers on the internal router bus through a common port. The DMAC utilizes a novel bus protocol that allows for selectable bandwidth allocation for each channel. The router architecture also incorporates various interface circuitry integrated onto the silicon chip, including user-definable input/output (I/O) pins with programmable pulse width detection. This user-definable I/O enables synchronous and asynchronous interfacing with peripheral devices that have different timing constraints. Furthermore, the interface circuitry includes a DRAM controller with a programmable timing control circuit that operates with memory devices of varying timing and memory block sizes.
