Inevitable Use of TAP Domains in SOCs
نویسنده
چکیده
The 1149.1 TAP controller has proven to be an effective test interface for ICs on boards using its standard 4 pin interface (TCK, TMS, TDI, TDO). One of the most important features of the TAP is its Protocol, which provides an easy to follow Plug & Play IC test interface. This Protocol defines and enforces; (1) a Test Reset Mode, (2) a Run/Test Idle Mode, (3) an Instruction Scan Mode, and (4) a Data Scan Mode. IC level IEEE standards that currently use the TAP Protocol include; IEEE 1149.1 (the Boundary Scan Standard), IEEE 1149.4 (the Mixed Signal Test Bus Standard), IEEE P1149.6 (a proposed Advanced Digital Interconnect Test Standard), IEEE 1532 (an In-System Programming Standard), and IEEE 5001 (a Silicon Debug Standard) . Further, numerous companies/consortiums use the TAP protocol at IC level to support various silicon debug, emulation, and code development strategies. As these users of TAPs migrate their products from individual ICs to reusable IP Cores, it appears inevitable that Systems-on-Chip (SOC) will include more and more embedded TAP domains.

Floodwater spreading (FWS) has an important role in floodwater control, groundwater recharge, restoration and enhancement of vegetation and desertification control. Since the flood causes the transporting of soil particles including organic materials, the floodwater spreading project can be a suitable place to sequestration of organic carbon in sediment yielded by flood. The knowledge of soil o...

SOCS-1 (suppressor of cytokine signaling-1) is a representative of a family of negative regulators of cytokine signaling (SOCS-1 to SOCS-7 and CIS) characterized by a highly conserved C-terminal SOCS box preceded by an SH2 domain. This study comprehensively examined the ability of several SOCS family members to negatively regulate the gp130 signaling pathway. SOCS-1 and SOCS-3 inhibited both in...

0272-1732/02/$17.00 2002 IEEE The advent of the core-based system-on-a-chip (SOC) and reuse methodologies enables integration of cores from different sources into a single chip. Compared with the traditional multichip system on a board, SOCs offer benefits including higher performance, lower power consumption, smaller size, and so on. Different types of cores are usually incorporated into a s...
متن کاملThe SOCS proteins: a new family of negative regulators of signal transduction.
The negative regulation of cytokine signaling, with the exception of the tyrosine phosphatases, is not widely understood. We recently identified a new family of negative regulators by retroviral expression of hematopoietic cDNA library in the monocytic leukemic cell line, M1. This was coupled with selection for cells that were no longer able to differentiate in response to interleukin-6. From t...
