A Review of System-On-Chip Bus Protocols

Abstract

This paper gives a brief description of various on-chip bus protocols such as the Advanced Microcontroller Bus Architecture (AMBA) Advanced High-Performance bus (AHB) and Advanced Extensible Interface (AXI), Wishbone Bus, Open Core Protocol (OCP) and CoreConnect Bus. It gives a brief introduction of high performance system-on-chip bus protocol termed as the master-slave bus (MSBUS). By taking into consideration the inevitable trade-off among area, throughput and energy efficiency, the control bus is developed as low-cost and lowpower bus whereas the data bus is created as a high-throughput full-duplex bus. This on-chip bus protocol is differentiated from other on-chip bus protocols with feature of efficient block data transfer. This MSBUS is an effective bus protocol in many applications such as image processing, computer vision, and wireless communication where it requires less hardware resources and achieves higher performance, especially in block transfer mode. The comparison is made between different protocols with respect to various parameters.

A novel Ethernet based processing system for remote source harmonic detection

“…Figure 1 shows the block diagram of the designed embedded processor system with Ethernetlite IP core that acts as a media access controller (MAC) operating with interrupt active mode [6]. The designed system uses a processor local bus (PLB) interconnect module that acts as a system bus [22], multi-port memory controller (MPMC) [23] to control a 128 M byte dual data rate memory (DDR-SDRAM) read/ write operations, an interrupt controller (INTC) [15] to deal with the Ethernetlite IP core and timer interrupt signals and timers [17]. The system hardware also includes the necessary peripherals for proper operation.…”

Voice Biometric Systems for User Identification and Authentication – A Literature Review

“…Apart from adoption, more importantly, the maintenance budgets should be planned properly. This is always a key challenge that should be clarified from the customer's and dealer's side [46]. (c) Functioning Hurdles: Many issues affect the function and authentication of voice biometric systems such as multiple voices during data collection, short utterness and bandwidth usage and availability of the used app.…”
