Getting Started
The HSP-EVAL was designed to operate in conjunction with
daughter boards designed for the HSPXXXXX family of DSP
products. A simple procedure for assembly and operation of
the target daughter board with the HSP-EVAL is described in
the respective daughter board’s User’s Manual. What follows
in this document is a detailed description of the HSP-EVAL
and its operation.
Bus Structure
The HSP-EVAL utilizes a series of 16-bit busses for daughter
board input, output and control as shown in Figure 1. The
input and output busses interface the daughter board to the
outside world through 96 Pin DIN connectors conforming to
the VME J2/P2 connector standard. Daughter board control is
provided by register driven control busses down loaded with
data via the parallel port of a PC. For added flexibility, the
input busses may also be register driven with down loaded
data.
Two input busses, IN1_0-15 and IN2_0-15, bring data from
the 96 Pin DIN connector (P1) to the daughter board through
the 50 position Input Connector (J1). Each input bus is 16
bits wide and the signal mapping for the above connectors is
given in Tables 1 and 3. As an alternative, the input busses
may be driven by registers which have been down loaded
with data through the Parallel Port Bus.
Two output busses, OUT1_0-15 and OUT2_0-15, carry
daughter board output from the 50 Pin Output Connector
(J2) to the 96 Pin DIN connector (P2). Each output bus is 16
bits wide and the signal mapping for the above connectors is
given in Tables 2 and 4. A shift register is provided to
serialize data on the output busses for transmission via the
Parallel Port Bus.
A status bus, STAT0-3, maps four status outputs from the
daughter board Output Connector J2 to the Configuration
Jumper Field (J4). The Configuration Jumper Field is used to
select one of the four status lines for transmission via the
Parallel Port Bus (see Configuration Jumper Field Section).
The two control busses, IN3_0-15 and CTL0-15, connect a
set of registers to the 50 Pin Control Connector (J3). Each
control bus is 16 bits wide and the signal mapping for the J3
Control Connector is shown in Table 5. The four least
significant bits of the CTL0-15 bus are also used to control
the operation of the HSP-EVAL (see Register Structure
Section). As with the registers driving the input busses, the
registers driving the control busses are down loaded with
data via the Parallel Port Bus.
Parallel Port Bus
The Parallel Port Bus carries the data and signals required
to support bidirectional data transfers between the HSP-
EVAL and the parallel port of an IBM PC or compatible. The
port bus contains eight data lines, PCD0-7, two control lines,
PCWR0-1, and three serial output lines, PCRD0-2. The con-
trol and data lines are used to down load data into the HSP-
EVAL's on board registers via the Parallel Port Interface. The
serial output lines carry daughter board status and output
serialized by the On Board Shift Register.
