Specifications
This section contains specifications for the TMSST1
775-Pin Socket
hardware
support.
Circuit Description
The TMSST1 probe adapter hardware uses a custom ASIC to preprocess all
signals on the microprocessor before the signals are captured by the logic
analyzer. The custom ASIC performs the following functions:
H
Latches signals within a narrow valid window
H
Demultiplexes double-pumped, source-synchronous signals
H
Deterministically synchronizes source-synchronous signals to BCLK
The ASIC latches all signals on the microprocessor. The latched signals are
processed in the ASIC according to their type. Following is a description of each
type:
4x Quad-Pumped Signals.
These signals include D[63:00]# and DBI[3:0]#. The
ASIC latches these signals using their dedicated strobes, STBP[3:0] and
STBN[3:0], and then performs four-way demultiplexing on these signals. The
ASIC also inverts the appropriate signals when the DBI[3:0] signals are active.
2x Double-Pumped Signals.
These signals include A[35:03]#and REQ[4:0]#. The
ASIC latches these signals using their dedicated strobes, ASTB[1:0], and then
performs two-way demultiplexing on these signals.
1x Common-Clock Signals.
These signals include all of the remaining front-side
bus signals. The ASIC latches these signals using the rising edge of BCLK.
